  • Not detected on cold boot
    Reviewed by saphire - February 10, 2022

    Drive is not detected on cold boot It is a well known issue by WD and here is how they adress it: https://support-en.wd.com/app/answers/detail/a_id/31851/kw/sn850%20not%20detected ISSUE: WD_BLACK SN850 is not detected by computer on cold boot, but does work after a restart. SOLUTION: Enter your computer BIOS and exit The computer should now detect the drive and boot as normal. In the end boot time will be longer than a boot from an hdd Simply pathetic. Why should anyone buy such a piece of crap

  • SUPER fast and reliable boot drive!
    Verified BuyerReviewed by themaltese - July 9, 2021

    Very happy with this NVMe drive, especially after getting it at a great price on here! I ordered the version without heatsink because my MSI motherboard has a heatsink over the M2 slot. I installed this as the boot drive for my Windows 10 Pro system, along with 2x1T WD Black HDDs as program and media drives. Overall, my system runs great!

  • Stop waiting, buy it. Exceeds expectations.
    Verified BuyerReviewed by T.rK - June 10, 2021

    Exceeds expectations. Blows away my previous Gen 4.0 Nvme m.2 SSD a Sabrent Rocket that couldn't sustain it's performance day to day. My SN850 meets all stated specs, all the time and stays nice and cool. Clean unobtrusive management and firmware upgrade software as well. Truly 5-Star.

  • Perfect for PS5!
    Verified BuyerReviewed by Retro - January 4, 2022

    Worked perfectly for my PS5 and did not compromise in speed at all! Really glad I went with this SSD. Was just what I needed as my space was full on my PS5 internal SSD and I was having to delete and reinstall games just to play.

  • Quality Product
    Verified BuyerReviewed by Ian G - November 11, 2021

    It was easy to install this SSD and get it up and running. This was my first computer build and it seems like a quality product. I have not been running it long, but everything has been smooth.
