This U.2 to PCIe adapter lets you add a high-speed, U.2 (4-lane PCIe) 2.5"" NVMe SSD, such as the Intel 750 Series drive, to a PC with an available x4 PCI Express expansion slot. You can mount the PCIe U.2 drive directly onto the adapter, giving you an easy and convenient way to improve your system performance and expand overall internal storage. Boost your system speed and performance The expansion card lets you take full advantage of the fast performance and compact size of PCIe U.2 internal solid-state drives. The adapter connects directly to your computer motherboard to support an NVMe U.2 PCIe-based SSD through ultra-fast x4 PCIe. With the U.2 PCIe-based drive in place, the adapter gives your computer a significant speed boost. Easy to install The expansion card is equipped with a full-profile bracket and doesn’t require an adapter cable for installation, this helps to reduce clutter and simplifies system builds. The drive connects directly to the SFF-8639 connector on the adapter, and the adapter connects directly to the computer motherboard. The adapter is compatible with PCIe 3.0 motherboards and is also backward compatible with PCIe 2.0 and PCIe 1.0. The PEX4SFF8639 is backed by a StarTech. "

The "go to" adapters when it comes to broad compatibility.Surprisingly works also with PCIe 4.0 drives.Tested on Seagate Nytro 3530S

I installed it on my server, and everything works well. I hope they offer U.3 variants for PCIe 4.0.

Worked great out of the box with my optane drive and windows 11. My only issue is that it did not have thread locker on the 4 screws. Great product. 👍

Adapter card works as it is supposed to. I am using an intel 4TB u.2 nvme ssd with this adapter in my media server. Works great, but under sustained loads, it gets very warm/hot. Adding an additional fan to this area helped keep it under manageable levels.

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.

Item was much pricier than some of the other unbranded options, but at least it works.

Bought this about a year ago. Installed a Intel Optane 905p, 960GB 2.5" SSD. It has successfully run very heavy workloads 24/7, with sustained data rates for 1.0GB/sec since. No hesitation to recommend this product.

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 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.
