MZHOU M.2 NVME SSD to PCIe 4.0 X4 Adapter, Supports Key-M NGFF PCI-E 3.0, 2.0 or 1.0 Controller Expansion Card (2230 2242 2260 2280 22110 M.2 SSD)

This adapter will let you use a fast NVMe SSD hard drive in the PCI Express slot of an older motherboard that doesn't have an M.2 slot, or add another M.2 slot to a board that already has them. Best of all, it works, and took absolutely no faffing about to use.The adapter uses a x4 form factor so it will plug into an x4 slot or bigger. An M.2 drive only uses four PCIe lanes, so it won't transfer any faster if you put it in the longer slot - but it will work just fine. I've used this adapter on two different motherboards, in both cases with the same M.2 NVMe SSD hard drive, and plugged into a spare PCIe x16 slot.Installing the NVMe drive onto the adapter is easy - it plugs in at one end and is secured at the other with the 'bobbin' that came with the drive. A screw comes with the adapter if you need it. The adapter will only accept an M-keyed SSD. B-Key drives won't fit.The first motherboard was an old one (Asus P8Z68-M PRO) which has no M.2 slots built-in. It does have two PCIe x16 slots, one of which contained the graphics card, and the other was free. Although the x16 PCIe slot is much longer than the x4 adapter, I just plugged it in leaving most of the slot empty - as long as you line up the notch at the end, the card will work perfectly.My drive was brand new, so it wasn't formatted. The latest Windows update seems to have hidden Disk Management yet again, but once I'd found it, the drive was showing as ready to be assigned and formatted. If I'm honest, I was really surprised by that - it was a brand of drive I'd never used before, in an adapter I've never used, on a motherboard that's 11 years old!I tested the read / write speeds after the drive was formatted, and I got 792.17Mb/s sustained write. The drive is capable of 7100Mb/s, so it was being bottlenecked by the PCIe 2.0 bus. It's much faster than a SATA SSD, but a bit of a waste of a really fast NVMe drive!Having confirmed that the adapter and drive both worked as expected and were probably not going to destroy my PC, I swapped them both into my main PC. My Asus prime Z490M-plus motherboard does have two M.2 slots, but if you use the second one it disables one of the SATA connections - and I'm using all of them. Since I had a spare PCIe x16 slot, I thought I might as well use it.I was slightly confused by my test results this time - I only got a write speed of 3452Mb/s when the drive is capable of about double that. On further investigation, I discovered that my PCIe slots are only 3.0 not 4.0, so again, it's my PCIe bus that's bottlenecking the speed. Nevertheless, it's massively faster than an SSD through SATA 6, and in real-world situations loading games, the difference in transfer speed between PCIe 3.0 and 4.0 makes almost no difference to the loading times.I have a Samsung 970 EVO in the first M.2 slot so I took the opportunity to compare the read / write speeds of my new drive through the adapter against it. There was no appreciable difference - the adapter will transfer data as fast as my PCIe bus will go. It's worth mentioning that this adapter can ONLY transfer as fast as your PCIe slots are capable of - if you only have PCIe 3.0 slots, this card won't magically make them PCIe 4.0.For less than a tenner, I'm really happy with this adapter. It's enabled me to install a very fast NVMe drive without losing a SATA connection.

When I was close to filling up yet another hard rive I thought I'd get some more storage but became aware that i had some new (to me) options. After doing a bit of research I settled on this adaptor and matched it with a suitable M.2 NVME SSD of a 1TB capacity. The installation was simple to do with the PC powered off and simply slotting it into a vacant PCIe slot on my motherboard. Once reassembed and powered back on the device showed up straight away and I intialised it as another drive. I have used it to store my most commonly used Steam games and to date its worked very reliably. Very pleased with it.

Bought this item to speed-up my son's hard-core gaming PC running on an NVIDIA RTX 4080. I extended the PCIe 3.0 slot, which was covered by the RTX 4080, with a 10Gtek PCIe Extension Cable, connected it to the MZHOU M.2 NVME card positioned in a free slot on the chassis and slotted a WD_BLACK SSD gaming drive. The process was simple enough and once the OS was transferred to the SSD and the PC made to boot from that drive, the system became significantly faster. Why 4-stars? Because the card is not as sturdy as the rest of the chassis, but it does the job so I would recommend it.

This adapter was really easy to install, literally just plug & play that's it, also came with the case fixing too but i didnt need it so i just unscrewed it which was a bonus. Worked fine with my Gen 4 ssd with no problems what so ever. Would buy from again if needed, ezdiy-fab make great products at okay prices, not all products that they sell i would buy.... but they have plenty of adapters/graphics card supports & stuff like that which is at a fair price & good quality which I would buy over normal brand products. In all I'm very happy with this purchase.

Working perfectly with my nvm disk

Did its job fine for over a year, used sporadically. When it failed, it went up in smoke, literally, and took the whole unit with it.

Brought this for my most recent build. perfectly fit into my case and motherboard.Speeds of an m.2 are typically high and this doesn't disappoint in its connectivity from M.2 to motherboard! (allows bringing most older Motherboards that don't have an M.2 slot to get those sweet sweet speeds!!)Didn't need any kind of drivers to get this to work so worked correctly right off the get-go!Couldn't have been any easier to install this to case and motherboard!

USB ports work fine but the nvme slot it like misshaped and my card doesn't fit. I was wondering maybe I have the wrong nvme card but in the motherboard it fits fine when comes to the adapter it just wouldn't go in
