Works with x4x4 bifurcation enabled in the bios settings

The GLOTRENDS 4 x M.2 PCIe 4.0/3.0 X16 Adapter is a game-changer! Setup was easy, and it instantly improved my computer's speed and storage management. The support for 4 x M.2 NVMe SSD RAID-on-CPU is excellent and compatibility with PCIe 4.0/3.0 X16 is a bonus. Especially loved how it handled large amounts of data with ease. If you need a storage management upgrade, this is a great buy. Highly recommended!

I was apprehensive about buying this card due to the number of people saying there's "missing M.2 screws" - turns out that those people are just plain dumb 😂 the two screws in the little plastic pouch are just for mounting the card to your case. You get 3x brass grommets on the board (2 located with the M.2 slots and one on the corner of the board as a spare.) you just unscrew them from the back and the brass grommet is used to mount the M.2 drive. Reason for 4 stars, instead of 5: Overall this adapter appears to be well-made and if I had the right motherboard then I've no doubt that it would work as intended - unfortunately the instructions on this listing are poorly translated and as a result, it turns out that although my motherboard is a B450 and has Bifurcation options, it doesn't seem to have the *right kind of Bifurcation*. This means that only one of those 2 M.2 slots is recognised (M.2 Slot 1) by my motherboard. Not a big deal at the moment as my C-Drive was only a 500gb SATA-M.2 drive so I just swapped it out. Read/Write speeds of the M.2 NVME drive mounted using this adapter seem to be around the 450MB/s mark - this is obviously a lot lower than the 3500MB/s that the NVME drive is capable of but this may also just be down to my motherboard not bifurcating the PCI-E slot correctly.

Works great on a z440 workstation once I set it up in the bios. I've had it well over a year, it's been on 24/7 hosting vm's and its performed very well. It cost around the £50 mark when I purchased it, so the value is great for me. Its hardware level compatability, so if your motherboard doesn't support bifurcation, don't get this.

Bought this for my system, installed np. Less than 30 days later, my system died, no post, VGA motherboard LED stuck on, rebooting every 70 seconds. A £5k custom system. Sent it back to the original builder, this card died in the PCI expansion slot. I thought this was a reasonable priced, simple addition, it costed me £250 extra for a specialist to rip this put and send my PC back to me. Not worth it.

Great neat x8 dual v4 nvme adpaters. Easy to cool and reliable across all machines I've tried even in dodgy extension cables etc etc.

Bought this to house my spare NVMe and works like a charm. Would recommend if you need a way of using if you have no spare slots left.

Doesn't work well with X670E-E MB. Don't waste your time playing with bifurcation modes or searching for a solution, you'll get only one m.2 working at best.

Ottimo, non rallenta la velocità della memoria montata.

Works perfect with the low profile adapter in my Power Edge R730! Be sure your motherboard or server supports Bifurcation as the listing says this unit does NOT bifurcate on the card.

Great nVMe expansion card. Works on PC's and most servers. Servers may need some BIOS tweaking but, on some servers, it just won't work.

Worked as advertised. Moved my GPU to the second slot in my ASUS ROG X870-A Gaming Wifi board and put this card into the primary PCIE 5.0 slot and set bios to bifurcate x4/x4/x4/x4. This freed up the other 3 NVMe slots on the mobo. Immediately recognized the three NVMe drives I mounted and they were running full x4 speed. Just remember that in order for this to work, your motherboard needs to support bifurcation.
