    • Full PCIe 4.0 x4 speeds through U.2 slot Full PCIe 4.0 x4 speeds through U.2 slot

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. ... show more

Works perfectly and adds that extra SSD slot that sometimes is needed.

    • Beware of PCI speed
Style: U.2 (SFF-8639)
Not good for PCIe Gen4, in a Tyan motherboard with good grade NVME drives needed to lowered the PCI in mitherboard bios to Gen3 to avoid timing issues.

    • As far as I can tell, a pointless product
Style: U.2 (SFF-8639)
I have a bunch of 250GB NVMe SSDs pulled from Dells. I figured I'd repurpose them for some older computers that don't have NVMe slots, so I bought one of these to test, with the intent to connect the NVMe drives to the older computers' SATA ports. Lo and behold, these don't have standard SATA connectors, they have SFF-8639 connectors, which are typically used by SAS drives (server-oriented). So, forget about connecting these to standard SATA controllers; you need to connect a RAID controller with a SFF-8639 breakout cable. The especially irritating thing is that SATA drives are compatible with SFF-8639 cables, but SFF-8639 drives are not compatible with SATA cables. IE, if this adapter had a SATA connector, you could use it with SFF-8639 cables AND SATA cables, but since it's SFF-8639, it will only work with SFF-8639 cables. Now, to be fair, it is entirely my fault for not being positive that this adapter was the right thing for my needs. My one-star rating is because I can't think of any practical reason to make an adapter that simply doesn't work with SATA cables and only SFF-8639. ... show more

Work as advertised. I put them in a heavily used server and the database team can't tell the difference between them and the U.2 drives next to them.

    • Excellent but be careful to get the right one.
Style: U.2 (SFF-8639)
Here is a fine product...even better if you get the right one. My point here is be careful to buy the correct adapter (and probably the SSD for it). I bought the listed unit before I opened the case on my laptop to check the plug type I had. I bring this up because I am a tech and should have known better ! My own machine, for Pete sakes and I messed up. These adapters are great, replacing the old mechanical drives. Of course it’s gotta be the correct one. The moral to the story ? This is an excellent adapter, nice and fast...a perfect compliment to the SSD assuming you get a nice fast SSD. Look ma ! No moving parts except for the fans. ... show more
