      5.0 out of 5 stars Maximus Impact VIII mobo + WD Black SN750
      Reviewed in the United Kingdom on 4 February 2020
      Verified Purchase
      Using this adapter and an appropriate U.2 cable (purchased separately) to house a WD Black SN750 NVMe drive to use as a VR game library.

      When both cables plugged in, detected the drive immediately. After formatting, drive was benchmarked through Crystal Mark - expected read / write speeds for an NVMe drive. The adapter does not appear to impede drive performance at all, much to my relief as it takes the sting out of having an odd motherboard with a U.2, but not M.2 PCIe inputs and allows for much desired NVMe speeds without forking out ludicrous amounts for a dedicated U.2 storage device.

      I would have preferred to see the the side rails at the M.2 standoff end fixed to the PCB as I use this in an ICY DOCK MB111VP-B M.2 to U.2 mobile rack system, but perfectly adequate for a permanent case installation.
      Gives good R/W speed results in my setup.

      Used 6 of these with Samsung 960 Pro and 960 Evo NVMe M.2 drives in an NVMe drive bay extension kit for a HP ProLiant ML350 Gen 9 and they all worked a treat - excellent performance, no compatibility errors or warnings and showed up straight away in DiskMgr. Couldn't be happier.

      5.0 out of 5 stars Full PCIe 4.0 x4 speeds through U.2 slot
      Reviewed in the United States on 12 February 2023
      Verified Purchase
      U.2 may be dead in the consumer space, but using this adapter we're able to convert the port to a standard M.2 port, since both use PCIe protocol natively. Now I can have 3x M.2 drives on my system natively!

      I'm pleasantly surprised to see full PCIe 4.0 x4 speeds through this adapter. My U.2 slot goes through the chipset (AMD WRX80), so 6.4 GB/s is about the max we can get. PCIe 4.0 U.2 ports connected directly to the CPU can get up to 7.5 GB/s. This adapter is simple and gets the job done.

      I do wish some kind of heat sink material was included with this adapter, as PCIe 4.0 M.2 drives tend to run hotter. But probably a non-issue unless you're hammering the M.2 drive with constant IO. Just mount this somewhere near the front of the case so the drive can get some airflow.
