Features and Specifications


MyDigitalSSD proudly introduces the BP4 Slim 7 Series, the 4th generation of their critically acclaimed and award-winning Bullet Proof line of solid state drives. BP4 Slim 7 drives are easy to install SATA III (6G) replacement upgrades designed to eliminate the bottle-neck found in stock hard drives to increase user productivity up to 70X.

Unlike their predecessors, BP4 drives have been over provisioned for improved Random Read/Write performance and IOPS, extended performance endurance to reduce sluggishness as the drive fills with data, prolonged drive life, reliability, and low power consumption - all at the unequaled price to performance ratio synonymous with MyDigitalSSD Bullet Proof SSDs.

Backwards compatible with SATA II applications; BP4 Slim 7 drives feature a 9.5mm drive screw hole alignment to upgrade virtually any notebook with a 2.5" SATA port or SATA desktop workstation using a standard mounting adapter bracket, PC or Mac.

About the Controller

MyDigitalSSD BP4 SSDs feature the Phison S-Module III S8 controller to deliver all the advantages of Flash Disk technology with the Serial ATA III interface, fully compliant with standard mSATA form factor. The S-Module III S8 is based on the mSATA form factor which is generated by JEDEC, designed to operate at a maximum operating frequency of 300MHz with 40MHz external crystal.

The S8 can reach 500MB/s throughput based on ONFI/Toggle NAND (with DDR3 cache enabled and measured by CrystalDiskMark) with markedly lower power consumption than that of a traditional Hard Drive.

Note: Solid State Drives DO NOT require defragmentation. It may decrease the lifespan of the drive.

Performance isn't the best, but more than fine considering the price. I'd buy one just because it isn't a ubiquitous Sandforce. Thanks for the review.

Samsung doesn't offer us samples for review, or they would be included. Regardless, all of the most popular SSD controllers are represented in our tests. Which Samsung SSD were you expecting to see?
