Specifications, Pricing and Availability
At the time of writing the MDSSD BP4 was just a preorder item on MyDigitalDiscount's website. There are three capacity sizes - 60GB, 120GB and 240GB. Today we're testing the 240GB and soon the 120GB review will hit our website. MyDigital has BP4 in mSATA variants as well.
This is the second time we've seen a Bullet Proof product with a Phison S8 controller. Phison increased the performance via new firmware. The main difference between BP3 and BP4 after flashing BP3 to the new firmware is the NAND flash. BP4 uses new 19nm Toshiba Toggle 2 NAND with 16K page sizes. The sequential read performance quoted by MDSSD is 560MB/s, the upper limits of SATA III. Sequential write quoted is 530MB/s. 4K aligned read tops 46K IOPS while 4K write IOPS is 79K.
The 2.5" drives will hit the market soon and with the following prices - 240GB ($179.99), 120GB ($99.99), and the 60GB ($64.99), all prices USD and pending list at Amazon and MyDigitalDiscount.com. The prices are very good for any SSD, but the performance offered is very good as well. BP4 is also MyDigital's first 7mm z-height form-factor drive for easy installation in new ultrabooks that require the reduced size.
