3D V-NAND goes to Warp 10 in Samsung's 950 Pro SSD


— 8:37 AM on September 22, 2015

The next-generation storage wars may be about to heat up. Samsung is firing off a potent opening salvo in the form of the 950 Pro SSD, its first consumer drive to combine 3D V-NAND flash memory and the NVM Express specification.

The 950 Pro uses an M.2 PCIe 3.0 interface to deliver up to 2,500 MB/s sequential reads and sequential writes as fast as 1,500 MB/s in its 512GB form. That same drive can perform random reads at a blistering 300k IOPS and random writes at up to 110k IOPS. Sequential writes aside, those are all healthy increases from the SM951, the last Samsung PCIe SSD we tested.

Samsung builds the 950 Pro using its 32-layer, 128Gb V-NAND flash dies, which are rated for 200TB of writes in the 256GB 950 Pro and 400TB in the 512GB version. As expected from high-end SSDs, the 950 Pros offer hardware encryption support, and they're compatible with Samsung's Magician software (unlike the SM951). The drives will hit the market in October with a $200 suggested price for the 256GB model and $350 for the 512GB drive.
