    The SN770 & SN850X series SSD's from WD will work out of the box on a much greater variety of systems without firmware updates or other workarounds.

    I bought two 4TB WD SN850x and these are very fast NVMe drives! They have great random read and write speeds and do not run hot on my motherboard. They average around 42c temps.

    When I needed more storage for my Steam library, this stick fit the bill. M.2 prices continue to fall, definitely worth the upgrade if your machine has a slot.

    Read/write performance is top notch. A little bit cheaper than similar drives due to no heat sink. Most motherboards come with heatsinks with m.2 drives so is usually a non issue.
