    Well, the card was extremely easy to install. Literally just put the SSD on the adapter, and put the adapter in a PCIE slot. There wasn't even any windows drivers to install. I just ran a basic benchmark with Samsung Magician software, and I don't see any meaningful performance loss. (That micron drive is rated for 3500 Sequential Read and Write... I got 3465 read and 3355 write)

    I've been benching a lot of M.2 and U.2 NVMe SSDs for work lately. While you'll find M.2 slots (1 or 2, anyway) on many consumer-level desktop motherboards, I haven't found many workstation/server boards with U.2 interfaces, unless they're supposed to be in a 1U or 2U form-factor server chassis.

    So that's where this item comes in. It's decidedly no-frills, but that's not really much for this board to do. It's essentially just taking a PCIe x4 slot and giving you an SFF-8639, along with enough card to screw the actual SSD to. I took this board and put it into a variety of SuperMicro, Tyan, Asus, and HP servers/workstations. Generally, my findings were good. In all cases the drive was usable, and in most cases it could be made the boot drive. Check your OS compatibility. Also, you'll want to make sure your motherboard chipset supports it.

    So, a device like this basically a commodity. It either works, or it doesn't. There aren't really opportunities for differences in performance, from brand to brand. This item worked with several Intel U.2 NVMe SSDs, and there's no reason to think it wouldn't do the same with any other SSDs. In a top-position horizontal riser, there's no interference with the lid of the server cases... and that's about the only thing I think could possibly go wrong. RECOMMENDED.

    Mated this to a Micron 9100 SSD. It works just fine with my Desktop PC. Simply plug and play. However, when I tried installing on my server PC. Dell T420, I didn't have any luck. the PC threw a hardware error. I then tried an alternative solution with a different card that makes use of a cable to connect to the drive with the added benefit of dedicated power. However, that approach also failed to work, the server threw the same error. Looks like some machines will run into a hardware compatibility issue with the drive itself as opposed to the adapter. Would be nice to know how to trouble shoot or address this type of issue.

    I've been running one of these since 2019 and just ordered a second one now. Both are working well. The new revision does have a jumper on it for compatibility?! I'm not sure what that is exactly about but ignoring that change both work well and have identical performance.

    I would recommend spending the little extra for this over the cheaper ones if you care about reliability.

    Using this with an Intel Intel DC P4600 2TB (SSDPE2KE020T7K1) enterprise U.2 drive. It worked perfectly right out of the box with Win10. No drivers needed. Drive was recognized right off the bat. StarTech makes great products. Don't be dissuaded if the StarTech version of something costs a few bucks more. You get what you pay for. This card is built well. Thick PCB, strong bracket, drive mounting holes all line up. Highly recommended.
