Targeted at gamers, the SN750 is WD’s third generation Black NVMe drive. The SN750 uses the same NAND/controller combination as the previous generation Black NVMe drive, but with updated firmware to push up the performance. is it a good SSD to be considering for a new system build in 2019?
The new drive is available in three capacities; 250GB, 500GB and 1TB (the drive we are reviewing here). Coming along very shortly will be another version of the drive with a stylish EKWB solid aluminium heatsink. This version of the drive will also bring with it a larger 2TB model.
The SN750 uses the same combination of WD’s own in-house NVMe controller and SanDisk’s 64-layer BiCS 3D TLC NAND that the previous Black NVMe drive used but with some firmware updates to get some grunt out of the drive.
WD quote Sequential read performance for the 1TB SN750 at up to 3,470MB/s which is 70MB/s faster than the previous drive but the writes get a healthy 200MB/s kick up from the previous drives 2,8000MB/s to 3,000MB/s. Random 4K performance is quoted as up to 515,000 IOPS for reads and up to 560,000 IOPS for writes which again is faster than the previous model, 15,000 IOPS for reads and a massive 160,000 IOPS for writes.
The endurance for the 1TB drive is stated as 600TBW and WD back the drive with a 5-year warranty.
