WD Ultrastar NVMe SSD for the Data Center

Designed for enterprise servers and data centers, the Western Digital Ultrastar DC SN640 NVMe SSD offers speed, reliability and low latency for both read and write intensive loads.

The Ultrastar DC SN640 NVMe SSDs are optimised to provide consistent quality of service and low latency for the mixed random read and write operations often generated by leading enterprise applications such as virtualisation, online transactional processing, NoSQL systems, web servers, file servers and email servers. The Ultrastar DC SN640 drive provides a smooth transition from SATA SSDs and offers superior performance for more complex operations, as well as increased processing speed for today's data-intensive applications.

    Very reliable and fast, for professional applications

    Very fast U.2 NVMe SSD - over 3,200 MB/s read and 1,200 MB/s write; very safe - data protected by supercapacity write in case of power failure; and very reliable - specifies 1.4 petabytes of write time, which gives it a few years before it wears out Perfect for large NAS or professional servers. Used in cache on a QNAP TS-h973AX-32G with excellent results: they do the job perfectly and are completely forgotten. The price is high, as is the case with all pro equipment (a Samsung 980 M.2 PCIE with U.2 adapter is 30% cheaper for even better performance, especially in terms of writing, but it has a lifetime limit of 600TB, 60 times less, and does not have the writing security of WD).
