Amazon listing details

Marketplace feature text kept for reference. Structured specifications above are the source for scores and comparisons.

PCIe Gen4 performance improves slow boot times and launches apps faster at speeds up to 5,000MB/s. (Based on read speed, unless otherwise stated. 1 MB/s = 1 million bytes per second. Based on internal testing; performance will vary depending on host device, usage conditions, drive capacity, and other factors.)

Storage up to 2TB* keeps your photos, videos and other important files within reach. (1GB = 1 billion bytes and 1 TB = 1 trillion bytes. Actual user capacity may be less, depending on operating environment.)

Slim M.2 SSD design utilizes a single-sided M.2 2280 to be compatible with thin laptops and small PCs.

Multitask with breathtaking responsiveness, transfer files faster, and improve your workflow with NVMe and Western Digital nCache 4.0 Technologies.
