The BP4 are 2.5-inch mSATA solid state drives of up to 240 GB capacity
Tablets, ultrabooks, hybrid notebooks, and desktop PCs can all benefit from using a solid state drive, and MyDigitalSSD did its best to make its newest drives in such a way that they are suited for all those types of products.It was a tall order though, so the company settled for releasing two drives with their own specialty, one with a 7mm thickness and the 2.5-inch form factor, one of 50 mm in mSATA form.
Since the capacities for both are of 60 GB, 120 GB and 240 GB, that means that MyDigitalSSD has released a total of six drives.
Other than that, few things set them apart, with the exception of physical size and connectivity standards.
For those that want to know specifics, the newcomers use 19nm Toshiba Type B Toggle NAND Flash memory chips.
They are also backwards-compatible with SATA II ports (SATA 3.0 Gbps) and capable of surviving, unscathed, “extreme shock and vibration.”
As for performance, it differs according to capacity. Unlike with HDDs, the speed of reading and writing actually increases with the capacity, due to the larger number of chips that can be written onto at once.
The 60 GB drives, regardless of interface, were found capable of 411 MB/s when reading and 99 MB/s when writing in CrystalDiskMark 3.0.2 x64.
The 120 GB ones reached 490 MB/s and 217 MB/s, respectively, while the 240 GB models achieved 484 MB/s and 219 MB/s.
The tests were carried out on a Lenovo Thinkpad X220 laptop, using a 2.5" SATA 6G Bay with mSATA to 2.5" adapter, Windows 8 and AHCI mode.
Another thing people might like to know is that MyDigitalSSD's newest drives have TRIM, DDR3 I/O interface support, RAID and SMART support, NCQ command set and a low power consumption (thanks to various power management perks). Shipments are already being carried out online, and will soon start through other retailers worldwide.
