JSER NGFF M-Key NVME AHCI SSD to PCI-E 3.0 1x PCIE4.0 x1 Vertical Adapter Compatible for XP941 SM951 PM951 960 EVO SSD

Bought one of these for its low profile capabilities initially. Ended up getting a second one for a full height desktop as well. "If it ain't broke, don't fix it". Working for some weeks now, no issues, thus my review.Samsung EVO SSD's used in both scenarios. But the only issue I had was not the fault of the adapter(s), just something to keep in mind when using these which is that it may not work as a boot device. In my case I have an Optiplex 3020 for the low profile and n ASUS B85M-G mobo for the other and I had to "hack" the BIOS to get these to be used as boot devices.Luckily for me others already did the hard work and then posted online on the process but again something to keep in mind if your motherboard's BIOS doesn't recognize nvme as a boot device.

I am thoroughly impressed with the exceptional quality of the JSER NVME to PCI-E 4.0 Adapter. The installation process was a breeze. I used it to effortlessly install and add a Samsung Nvme, and the performance is nothing short of remarkable. The thermal pad's effectiveness in keeping the Samsung SSD cool is a standout feature, ensuring consistent and reliable operation. This adapter works seamlessly even on older systems like my Dell Studio XPS, breathing new life into them. A truly outstanding product that exceeds expectations!

Simple little board for NVMe to pcie 1x, At first it was not detected (it is a x470 board), but that was my fault because the slot was disabled due to another NVMe using those lanes. Shifted to another slot and instantly detected on reboot. One must remember this is only a single lane and not 4, so the speed is not full, but I'm getting 581 MB/s write and for around $8 what more could I expect or want?

Cheap and does the job.

Product description says these don't work with B/M notched drives but in fact, at least for earlier Optane drives, they do! The B notch can denote either SATA type drives or NVME drives that use only 2 PCIe lanes rather than the more common 4 lanes. Reducing the Optane (815p 60gb) drive from 2 lanes to 1 in my case reduced peak read speeds from over1200 mbps to about 730 mbps (using AIDA64 Read Speed Test Suite), which is still better than any common SATA SSD. Write speeds likely similar. I haven't tried these with my WD SN500 drive which is also 2-lane NVME but I'd expect it would work. As always, YMMV but these are inexpensive enough to try if you have a PCIex2 NVME drive needing to go into an X1 slot! Only ding I'd throw at these is that the screws have rather small heads and require good lighting and manual dexterity to assemble!

I'm giving the Xiwai Low Profile PCI-E 3.0 x1 M.2 Adapter Card one star because the brass screw retainer, which must be pressed into a hole depending upon your M.2 drive length, is too large and doesn't fit. In fact even though I'm a retired embedded systems designer with decades of experience it was difficult for me to modify it to work.So you have two options if you must use this card.One is to use the brass retainer on the back of the card like a nut, however this forces the M.2 drive to actually contact the board. Although I tested this and it worked, it is not advised because there are too many exposed copper areas that might short out if they touch the board. You can use a piece of insulating material between the board and M.2 drive, but this is still going to bend the M.2 drive down and place stress on both it and the connector that they aren't designed for.The other, recommended, way is to file one side of the brass screw retainer so it will fit in the holes. Unfortunately though, this is much harder than it sounds. The brass retainer is very small and can't be held in your hands while filing. So I actually screwed the brass retainer into a corner hole on the board (intended for the PCI bracket), and then used a Dremel tool to file the brass retainer so it would fit (with some light hammering).However this must be done with the utmost care, because if you file it down too far it will be loose and won't stick in the hole, and if it's not enough and you try to hammer it in you might fracture the board. Also please do not use a Dremel tool freehand like this unless you are very, very, experienced because it's quite dangerous. If you're not comfortable with the Dremel tool, or don't have one, just use a regular small file.The only good news is that once I manually resized the retainer and carefully hammered it into the hole the board itself worked perfectly. Read/Write speeds are limited to around 800 MB/s, but that's because it uses one PCIE lane instead of four.However the bottom line is that this card is really not fit for its intended purpose because a casual user would not be able to assemble it correctly. So, really, look for another board unless you know how to work on small electrical/mechanical devices.

I liked that the adapter was compact and accepted the M.2 memory stick with ease. What I didn't like was it came with a spacer post that was threaded all the way through, but only came with one screw. Two are required, one to attach it to the board and another to hold down the memory card. You can't just go to the nearest hardware store and find this tiny screw, and it is much smaller than any of the leftover screws from the motherboard and disk drive installation.. I can't use the memory stick without both. If the vendor wants to send me a second screw I will gladly upgrade this rating to five stars.

I had been using usb mini WiFi on a new setup and was getting.5-2 mbps.This is like being plugged in for me.( cap 200 mbps )

fácil de instalar, trabaja bien y se ve de buena calidad

el producto es lo que anuncian, pero lo compre para una mac book 2013 el cual no me sirvio.igual fue mi error por no leer bien las descripciones.

Very good quality and happy with this product.

No lleva instruciones de como ponerla, sin embargo, es facil de instalar, solo tienen que colocar la rosca dorada en el M.2 y luego atornillar por debajo del adaptador la rosca con el M.2.

Il est reconnu sous windows et fonctionne super mais attention que si votre carte mère est assez ancienne et n as pas de port nvme natif vous ne pourrez pas installer le système dessus car impossible de demarrer sur le nvme. L adaptateur n est pas reconnu par le bios. Certaines cartes mères ont eu une mise à jour du bios pour pouvoir effectuer le pont pcie mais sans cela vous ne pourrez rien faire sauf si vous aimez vous casser la tête et faire un bootloader vous même. Bref en gros les anciennes générations de cartes ne démarrent que sur du SATA Saif si mise à jour et les ssd name sont en pcie...
