Known as the HG5d Series of Toshiba solid state drives, the cSSD (or client SSD) can be found in PC systems worldwide, however, is not available through retail sales. The HG5d cSSD family is comprised of 2.5? notebook, mSATA and M.2 form factor SSDs with capacities of 60, 128, 256 and 512GB. All speak to low power consumption, three-year warranties applicable only to manufacturing partners, and all take advantage of Toshiba’s newest 19nm Toggle Mode 2.0 MLC memory. The M.2 family of the HG5d cSSD is a SATA M.2 SSD and listed performance is variable, depending on capacity. Our sample 512GB M.2 SSD can reach 534MB/s read and 482MB/s write with 90KIOPS read and 35KIOPS write. 128 and 256GB capacities have the same read performance but write speeds are listed at 471MB/s with read IOPS a bit lower at 80K.
