    • Works well and good in enclosures too

I bought 2 of these high storage capacity M2 drives. I used one in enclosure and one in the micro pc. Easy to install and use. It does heat quickly and gets hot but I have placed a small heat sink. It has good read and write speeds. It is very durable. This is a good M-key SSD. Good value.

Capacity: 1TB Style: New Generation - M.2 2280
Review Image by Spencer Curtis Spencer Curtis
Picked this up to replace my main drive and couldn’t be happier. Speeds are blazing fast, system boots instantly, apps load without delay, and cloning my old drive went off without a hitch. Zero issues so far. I’d recommend pairing it with the Thermalright HR-10 2280 PRO heatsink for best thermals. With that combo, temps stay nice and low even under load. If you’re looking for a reliable high-performance NVMe drive, this is an easy choice. ... show more

    • I made this super fast WD M.2 NVME my Win 11 boot drive - fast, WD brand dependable & a good value.
Capacity: 2TB Style: New Generation - M.2 2280
I recently upgraded my computer from Windows 10 to Windows 11. I made this super fast M.2 NVME drive my boot drive and it brings up Windows 11 nice and fast (Windows operating systems have a habit of "dawdling" through lots of startup stuff, but this NVME drive installed in a M.2 slot speeds up the startup process nicely). It was a good value, for a dependable brand (good quality Western Digital), a fast choice compared to typical SATA hard drives or solid state drives other than NVME. I like the way it's performing! ... show more
