Western Digital has a new series NVMe SSDs launching today – the WD Red SN700. Built from the ground up to tackle demanding 24/7 workload environments, the new WD Red SSDs will be available with up to 4TB capacity.
The WD Red SN700 family includes a 250GB, 500GB, 1TB, 2TB and 4TB SSD. Unfortunately, the company has not revealed the controller being used, or the number of 3D TLC NAND layers, but we do have sequential read and write performance figures. The 250GB SSD is rated for sequential read/write speeds of 3100MB/s and 1600MB/s respectively. Speeds scale accordingly with capacity, so the 500GB version is capable of 3430MB/s and 2600MB/s, while the 1TB drive is capable of 3430MB/s and 3000MB/s sequential read/write speeds.
The 2TB and 4TB models offer the same sequential read speed, coming in at 3400MB/s, but the sequential write speed differs a bit, with the 2TB model offering up to 2900MB/s and the 4TB up to 3100MB/s.
When it comes to random read performance, the 4TB drive is the fastest at up to 550,000 IOPS, next up is the 1TB drive at up to 515,000 IOPS, the 2TB drive is rated up to 480,000 IOPS, the 500GB drive, 420,000 IOPS and finally the 250GB drive at up to 220,000 IOPS.
The WD Red SN700 NVMe SSDs come with a five year warranty and offer a typical endurance of 2000TBW. For more information and a deep dive into performance, check out our full review, HERE.
