MyDigitalSSD Is First to Market with Phison E8 NVMe Based SSDs

Posted by at 9:31 am on November 13, 2017

MyDigitalSSD was able to sweep the entry-level NVMe market with the SPX using Phison‘s PS5007-E7 NVMe controller and Toshiba 15nm MLC . The company’s NVMe SSD successor comes under the SBX name and uses the Phison PS5008-E8 controller. The smaller controller was designed to break new ground in pricing and power efficiency. This is Phison’s first true entry-level NVMe part for retail. The PS5007-E7 is targeted to mainstream users upstream.

The new PCI Express 3.0 x2 (lane) controller uses four channels to the flash. MyDigitalSSD was able to place all of the surface mount components on one side of the printed circuit board to reach the single-sided specification while still staying within the M.2 2280 form factor.

The drive comes to market in three capacity sizes: 128GB, 256GB, and 512GB.

The MyDigitalSSD SBX drives are available now exclusively at MyDigitalDiscount.com.
