Synology Disk Station DS209Thrifty shoppers are faced with many options when choosing where to store their valuable data: from traditional optical media and drive based storage, to flash drives and even more exotic third party online storage - each with its own advantages and disadvantages. In this article Benchmark Reviews tests the Synology Disk Station DS209 Gigabit SATA Network Attached Storage (NAS) server. The NAS has lately gained popularity as more and more consumers realize the need for a reliable, cost effective, and easy to access centralized way to store their data. However, with so many competing products it's not always possible for buyers to easily compare what's on the market. Read on as Benchmark Reviews puts this "all-in-one" NAS through its paces. Intended for small/medium business (SMB) and small office/home office (SOHO) users, The Synology DS209 offers a relatively inexpensive and easy to use data storage and backup that's sure to appeal to budget-minded users. When money is tight, people find new ways to reduce operating costs wherever they can. As a network administrator for several small and medium businesses, I'm used to seeing pedestal servers with expensive Windows Server edition Operating Systems running for the sole purpose of serving files out to the workgroup computers. These environments have made it necessary to look for money-saving opportunities elsewhere in the working environment. A few years back Network Attached Storage server hit the scene with a price tag comparable to the alternative, but the NAS products offered in today's market are far superior and cost much less than before. Business needs to continue as usual, even in times of financial distress. But the solutions to common problems are forced to move with the changing economic climate and the cost of providing a product or service is adjusted with the times. For many unknowing companies, a Network Attached Storage (NAS) server is the cost-effective answer to dodging the expense of pricy server configurations. All of the same functions are present, whether it's file storage and transfer, web serving, or media streaming.

Compared with PC server products, Synology products consume relatively far less power than their PC counterparts. It not only saves your money, but also saves The Earth. All Synology products are produced with RoHS compliant parts and packed with recyclable packing materials. Synology recognizes its responsibility as a global citizen and is continually working to reduce the environmental impact of the products we create. DS209 SpecificationsSynology Disk Station DS209 is designed to provide users with a flexible solution to share files and increase productivity. Packed with the Synology Disk Station Manager 2.1, it delivers ease of use and variety of features. Furthermore, the optional Synology 2.5" Disk Holder provides an easy way for users to deploy 2.5" hard drives on the DS209, bringing the library quietness, power saving, and higher reliability for the DS209. One unique feature of Synology Disk Station Manager 2.1 that wasn't available on the previous version (or other NAS products we've tested) is the inclusion of the Linux command-line interface (CLI). An apt LAMP admin can now browse through the Network Services section to Terminal, and access the command line interface from that location.
Closer Look: Synology DS209Every IT professional knows that time is money in the SMB and Corporate Enterprise sector, and any product that can cost less and deliver more while saving precious time is sure to be a popular commodity. The Synology Disk Station 2-Bay DS209 SATA NAS is a Gigabit network appliance which offers more features and functionality than most Windows domain controllers... for less than the price of a Windows 2008 Server Operating System alone! On the front of the white Apple Mac-like enclosure is a small collection of LEDs to display immediate status reports. Although the actual 'Status' LED will flash to a specific trouble pattern in the event of problems. the LAN, DISK1, and DISK2 LEDs give straight-forward activity feedback.
The Synology DS209 is geared toward home users as well as SOHO/Small Business environments, and one of the first hints is a HighSpeed USB 2.0 port above a unique 'USB Copy' button. A blue LED rests beside the power button, and can be easily seen from a distance.
The USB Copy feature allows the user to easily initiate content transfer between a USB-attached device and the DS209 NAS. There is a limitation however; since the DS209 does not offer USB Share and any attached device must be formatted with the FAT32 file system. The front USB 2.0 port can be utilized for connecting a flash drive, printer, camera, or external hard drive; and is joined by two more ports in the backside of the chassis.
The rounded profile and white plastic chassis of the Synology DS209 NAS follow a design trend made popular by the Apple iPod. Despite this, Synology has given the Disk Station the ability to stand on its own, without the need for gimmicks. Visible from the sides of the unit are the Power and USB Copy LED lights, which allows diverse positioning of the NAS without losing the ability to monitor the unit. In our detailed features section on the next page, the Synology DS209 will be disassembled and inspected for design flaws before we test for performance. Please continue on to learn more about this powerful little NAS product. DS209 Detailed FeaturesAt the rear of the Disk Station DS209 NAS accompanied by two HighSpeed USB 2.0 ports, there is a single RJ45 Gigabit Ethernet port for unrestricted network access. Beside it is a Kensington K-Lock hole, a system 'Reset' button, and the 12V A/C power adapter port. The grill above these components exhausts heated air outside of the inner hard drive chamber by way of a single 70x70mm cooling fan. To gain access to the inside of the DS209 NAS, two screws in the upper-right and lower-right corners must be removed, which allows the unit to slide apart and open. Despite a brute-strength attempt (and prior to reading the manual), the DS209 keeps a firm hold of the opposing half, and will not split apart by force. This translates to rugged durability if the unit should ever be accidentally dropped; and while the unit might suffer damage, it's far from a Fabergé egg.
Because of the compact design of this server, it follows the trend of many previously-tested NAS products here at Benchmark Reviews which use an external A/C power adapter 'brick'. To measure isolated NAS power consumption, Benchmark Reviews uses the Kill-A-Watt EZ (model P4460) power meter made by P3 International during our tests. Using the Kill-A-Watt tool, I was able to determine exactly how much electrical power the Synology DS209 consumes in empty, idle, and active modes. With no drives installed and with the DS209 in standby, the unit consumed a mere 13W of power. Once loaded with two hard drives (500GB Western Digital drives shown in image below, although 1.5TB Seagate ST31500341AS drives were used for performance testing) the idle (not standby) power draw was steady at 19W. Once the drives were formatted and file transfers began, the power demand increased to only 23W. It's evident that going green isn't difficult with these NAS products; something owner and administrators should keep in mind.
At the heart of the Synology Disk Station DS209 is a 1.2GHz CPU paired to 256MB of RAM, which may not be as exciting as the larger NAS servers we've tested which use desktop processors and high capacityDDR2 memory modules, but the performance results will prove that it's enough to get the job done. Even though a RAID-5 array is physically impossible for this two-drive unit, the Synology DS209 still offers excellent performance in RAID-1 or JBOD, and RAID-0 for those willing to risk data safety in lieu of performance. The CPU consists of an integrated (soldiered) Marvell Kirkwood 88F6281 (88F6-B1A2) processor control unit with no passive cooling heatsink. This controller chip includes a 256KB L2 cache, which operates at 400MHz when the unit is clocked to 1.2GHz. The system memory consists of a single Elpida E1116AEBG module. Although Marvell designed their Kirkwood controller to include two Gigabit Ethernet ports, Synology has customized the design to offer only one port.
Synology has included everything you will need to get the Disk Station NAS loaded and ready for duty-use. Although there might be future plans, at this time Synology does not include Hard Disk Drives with their NAS products. I expect that pre-loaded and pre-configured NAS servers with HDDs included will soon be a part of their product lineup, just as other manufacturers have started to offer. In this DS209 NAS kit there is enough hardware to mount all of the drives into their respective trays, along with a power cord and CAT-5e cable. My only gripe is with the enclosed network patch cable, which wasn't very impressive when you consider that most environments now use CAT-6 as a standard. Gigabit Ethernet will still perform well over CAT-5e, especially at short patch-cord lengths, but most IT professionals agree that this is yesteryear's standard and has since been replaced by CAT-6. The manufacturers cost is a difference of about two to three pennies per cord at 100-unit prices, so I really can't find a valid reason as to why every network product Benchmark Reviews has seen still comes with the old cables. I have personally seen all new network construction and retrofits utilize CAT-6 infrastructure and patch cords since 2006, so let's hope the manufactures catch on sooner than later. Network TerminologyBenchmark Reviews has decided to abandon our effort to educate readers on the difference between a Gigabyte, and a Gibibyte. This article will use the common metric terminology for data measurement, instead of the binary units we've used in past articles. Sadly, too many people are more interested in comfortable reading, even if it means being technically inaccurate. But for anyone who might still be interested in learning real technical terms relevant to the industry, I've added a small explanation below: The basic unit data measurement is called a bit (one single binary digit). Computers use these bits, which are composed of ones and zeros, to communicate their contents. All files are stored as binary files, and translated into working files by the Operating System. This two number system is called a "binary number system". In comparison, the decimal number system has ten unique digits consisting of zero through nine. Essentially it boils down to differences between binary and metric measurements, because testing is deeply impacted without carefully separating the two. For example, the difference between the transfer time of a one-Gigabyte (1000 Megabytes) file is going to be significantly better than a true binary Gigabyte (referred to as a Gibibyte) that contains 1024 Megabytes. The larger the file used for data transfer, the bigger the difference will be. Have you ever wondered why your 500 GB hard drive only has about 488 GB once it has been formatted? Most Operating Systems utilize the binary number system to express file data size, however the prefixes for the multiples are based on the metric system. So even though a metric "Kilo" equals 1,000, a binary "Kilo" equals 1,024. Are you confused yet? Don't be surprised, because even the most tech savvy people often mistake the two. Plainly put, the Kilobyte is expressed as 1000 bytes, but it is really comprised of 1,024 bytes. Most network engineers (myself included) are not fully aware that the IEC changed the way we calculate and name data chunks when they published the new International Standards back in December 1998. The International Electrotechnical Commission (IEC) removed the old metric prefixes for multiples in binary code with new prefixes for binary multiples made up of only the first two letters of the metric prefixes and adding the first two letters of the word "binary". For example, instead of Megabyte (MB) or Gigabyte (GB), the new terms would be Mebibyte (MiB) or Gibibyte (GiB). While this is the new official IEC International Standard, it has not been widely adopted yet because it is either still unknown by institutions or not commonly used. Personally, I think the IEC took a confusing situation and simply made it more of a mess. As I mentioned earlier, the Kilobyte was previously expressed as 1000 bytes, even though it was really comprised of 1,024 bytes. Now, the Kilobyte really is expressed correctly as 1000 bytes, and the Kibibyte is the item comprised of 1,024 bytes. In essence, the IEC just created a new name for the binary item and left the existing name for the metric item. Hopefully that clears things up, and you can thank Benchmark Reviews for training the next generation of Network Engineers. NAS Testing MethodologyAlthough each of the devices we tested can accommodate several different disk configurations, it was decided that basic (single) disk and RAID-5 configurations were the best way to measure data throughput for our NAS servers. Connected directly to the Realtek RTL8168 Gigabit Ethernet NIC by a three-foot CAT6 patch cable, the NAS products received one test transfer followed by three timed transfers. Each test file was sent to the Seagate 1.5 TB 7200.11 SATA-II HDD installed in the NAS for a timed write test, and that same file was sent back to an identical Seagate 1.5 TB 7200.11 HDD drive (ST31500341AS) in the test system to record the read test. Each test was repeated, and the first three identical results were recorded and charted. The two transfer tests: read and write, were conducted on each NAS appliance using the 100 MB file and then the 1 GB file. Additionally, a second set of tests were conducted with Jumbo Frame enabled. While the Synology Disk Station DS209, DS408, Cube Station CS407, and QNAP TS-409 Pro/TS-209 Pro each offered 9000K MTU Jumbo Frame settings available, the D-Link DNS-323 and QNAP TS-509 Pro do not. In the Jumbo Frame tests the Realtek RTL8168 Gigabit NIC was set to use the 4K MTU value with Jumbo Frame enabled. For the sake of benchmark results, the TS-509 Pro was also tested in the RAID-5 configuration (four disks), and included 10 GiB file transfers. NAS Comparison Products

NAS Testing ResultsWith so many features available to offer a broad range of functionality, NAS server products can be daunting when you try to nail down performance. In this article, Benchmark Reviews will refer to performance as the bandwidth speed results of a file transfer test. The first tests we perform utilizes a single 1GB (1000 megabytes / 1,000,000,000 bytes) file in a transfer to and from the NAS. This test used to take as long as a minute back in 2007, but in the past few years there have been major gains in NAS transfer performance. Now our 1GB Read test ends in as little as seventeen seconds (with the QNAP TS-509 Pro). Using an FTP tool so that exact transfer time could be captured, each NAS was tested for transfer bandwidth. As you can see for yourself in the chart below, QNAP has certainly set itself apart as the dominate force in file transfer speed. The TS-509 Pro doesn't offer Jumbo Frame support so all of our tests use the same result twice; but even without the extra packet size we see that QNAP has designed for optimal transfer performance. At 58.8 MB/s read bandwidth the QNAP TS-509 Pro is our highest 1GB performer, with the QNAP TS-119 and Synology DS408 coming in close behind with a best of 55.6 MB/s each with Jumbo Frame. The Thecus N7700 comes in right behind the top three leaders, with a best of 50.0 MB/s, matching performance with the Synology DS209.
Moving on to the 1 GB write bandwidth test, our results suggest that sometimes it will be faster to read files from a NAS server then it is to write files onto it, and sometimes the opposite is true. The Network Attached Storage servers each have their own strengths, with some being more robust in write-to performance when others conformed to the traditionally impressive read-from performance. QNAP's TS-509 Pro maintained 62.5 MB/s without the comfort of Jumbo Frame support, followed by the Thecus N7700 which produced a best of 62.5 MB/s. The Synology Disk Station DS209 narrowly beat the larger DS408, and scored a swift 43.5 MB/s write performance with Jumbo Frame enabled. A single-drive QNAP TS-119 held a steady 33.3 MB/s speed, scoring the same with and without Jumbo Frame enabled, and was tailed by the Thecus N3300 at 32.3 MB/s.
The lower-end spectrum consists of all the remaining NAS products, with the next closest competitor being the QNAP TS-409 Pro which reached only 20.3 MB/s write performance using Jumbo Frame, and 16.5 MB/s without it. The older Synology CD407 performed at roughly half the speed of its newer predecessor, and the remainder of the bunch trailed distantly behind. Let's move on to the larger file chunk testing, because next up is our 10 GB (1000 metric megabytes / 10,000,000,000 bytes) tests. Using only a single hard drive for testing in each NAS, network throughput would be put to the test.
Fresh out of the gates, QNAP's TS-509 continued to impress us with the high-bandwidth read performance of 55.6 MB/s that lead the pack. QNAP's single-drive TS-119 offered the same performance once Jumbo Frame was enabled, but reduced to 47.6 MB/s at 1500 MTU. The Synology DS209 and DS408 maintained a close relationship with peak performance around 47 MB/s in normal mode, and improved to 49.3 and 48.3 MB/s read performance with Jumbo Frame enabled at both ends (respectively). The Thecus N7700 was able to sustain 44.5 MB/s using Jumbo Frame, and 41.5 MB/s without it, which was very similar to the N3200 Pro. In our 10GB write performance tests, the charts were shuffled a bit. The Thecus N7700 makes up for above-average read performance by offering excellent large-file write performance and sustained 56.2/58.8 MB/s in normal and Jumbo Frame modes. Next was the TS-509 Pro, which has held the top position for most tests, and scored 47.0 MB/s. The Synology DS209 and DS408 have performed in the middle of the pack for our 10GB file transfer tests, and performed at 42.9/40.0 and 36.8/36.3 MB/s in normal and Jumbo Frame modes.
The single-drive QNAP TS-119 and three-drive Thecus N3300PRO both score around 32 MB/s in our large file JBOD tests, and trail behind the leaders by almost 20 MB/s. Taking the entire test section as a whole, one thing becomes abundantly clear: QNAP keeps the bar high for NAS performance with their Turbo Station TS-509 Pro, even when compared against newer products.

NAS Server Final ThoughtsIt's not going to make a lot of sense for resellers and IT professionals to outfit a client with a Windows-based server if it's only going to be used for serving out files, sharing printers, and controlling Active Directory objects; one fairly inexpensive NAS does all this in its most basic form at less than half the cost. It's not until you consider that some manufacturers outfit their NAS series with full LAMP (Linux Apache MySQL and PHP) package for web servers, along with FTP and media tools, that the list of items a NAS product could potentially replace grows very large. So what can you expect from most NAS products? More than you can with some pedestal or rack servers. This is supposed to be my final thoughts, and quite frankly I just barely touched the surface of features NAS products can offer. Most of my NAS reviews focus on performance, and sparingly supply feature lists. So let's recap some feature highlights that most modern NAS products offer:
Obviously the list could go on and on, especially if you noticed the multi-page layout of features and functionality. Taking into consideration that NAS products seem to all offer a feature-set that reads like a chefs shopping list, it's no wonder why these NAS products are quickly replacing Windows Server products. After all, for the price of one RAID-5 capable NAS and three 2.0 TB SATA-II HDDs you'll get four Terabytes of total storage space and still spend well below the cost of one single Windows Server Operating System and the required client access licenses. While it's true that these NAS products will do almost everything a Windows Server platform can, they still fall very short of one important task: Windows software. Many of my clients have servers which require some form of server-side software to manage a database. Some of the most common applications that require almost no processing power but still require installation on a Windows O/S are QuickBooks and AutoCAD licensing server. Imagine the possibilities you could offer clients with a full server-in-the-box solution. I believe that this will be the next evolution in NAS products, as consumer demand more versatility out of their investment. But there are still a few more things you can't do on a NAS, such as utilize the onboard O/S to install applications. Most NAS products utilize a Linux variant ('Nix) with little or no command interface, so even if you knew how to install from YUM or a similar repository the functionality doesn't exist. Even once that obstacle is navigated, I have a feeling that users will then demand a Windows emulator so they can install and utilize Windows-specific software on their NAS (such as license servers and anti-virus command points). It seems that these problems all revolve around side-stepping Microsoft products and licensing, which is not surprising. Synology Disk Station DS209 NASBenchmark Reviews believes that manufacturers should be educating consumers with their product packaging, so they can make the most informed decision possible before they make the purchase. This is why we rate the retail package presentation. in terms of the DS209 NAS this rating is average because Synology has done an excellent job of informing buyers with basic on-the-box specifications and feature information. It doesn't hurt that they've got plenty of room, as the retail package is very large in comparison to most products. The concept of truth in advertising is getting further and further away every year, but for once I can see that not every company is out to cover their product with catch phrases and slogans and instead educate the consumer. If you're a fan of Apple products, such as the iPod or Macbook, then you'll appreciate the design Synology has used for the Disk Station DS209 NAS. The simple white chassis with soft round corners helps to keep this network storage server from appearing like a real square (50's throw-back pun). Whether the DS209 finds itself on the shelves of a home office, or atop the cabinets of a small business, the Disk Station NAS looks like it belongs and fits in well. Synology has built one solid little NAS out of the DS209. The plastic enclosure is thick enough to sustain direct impact without suffering damage, while the rest of the unit inside is constructed of steel. Not that a network appliance will see a lot of careless handling or harsh environments, but the DS209 appears to be built prepared for the worst. Opposite of a gloss black finish, the white exterior doesn't show scratches and is small enough to be flexible with stationary mounting positions. Ever since Gigabit Ethernet found its way into the mainstream, bandwidth throughput has gradually grown for all products involved. The Synology DS209 enjoys these benefits, and performed as well as the best competition we compared it to for our benchmark tests. Single-drive (JBOD) read bandwidth was good compared to the competition, which topped-out at 50 MBps with Jumbo Frame. Write-to performance was more impressive compared to the competition, and measured 43.5 MBps. The list of functionality and features for every Disk Station NAS is practically endless, and this is especially true for the DS209. There's plenty of depth to the different modules, which might be considered too much for one device since it's close to overwhelming for a seasoned IT professional like myself. But as the saying goes: "It's better to have and not need then to need and not have". All that's missing is the ability to install software to emulate a Windows environment. Home and small business environments have never seen so much value in a high-performance multi-function NAS. As of late May 2009, the Synology DS209 is available at NewEgg for $295.99 without drives. Small business IT consultants can fill both drive bays with 2.0 TB SATA HDDs and configure a RAID-1 redundant disk mirrored array for less than $800. Dell and HP offer basic servers that supply only a fraction of the storage space for more than that price, so the value is obvious. Home users not needing the highest-capacity disks or data redundancy can still get 2TB of storage using 1TB Seagate 7200.12 HDDs for only $100 each. The Synology Disk Station DS209 Gigabit 2-Bay SATA NAS server is going to be an excellent alternative to the basic workgroup and domain-level file servers most resellers use for small business networks, and the additional functionality should not go overlooked. Home users can take advantage of RAID-1 data mirroring, but it's functionality and storage capacities that will excite them most. Whether you find yourself positioning the DS209 in a home, SOHO, or business environment, just remember: this little workhorse wears several hats, and does it fairly well. Pros:
