Gigabyte GC-4XM2G4 (AORUS Gen4 AIC Adaptor, Full PCIe 4.0, Advanced Thermal Solution for PCIe 4.0 SSD)

This unit was a bit pricey for what it is I thought. But upon receiving it I must say it’s built extremely well. This thing is heavy and solid and feels professional. I am running 4 PNY XLR8 1TB drives on a Gigabyte Aorus Extreme X-399 (Threadripper) board. On boot I double checked bios settings and set it up in windows, it has ran without a hitch. I do not have any software for testing read/write but moving files etc seemed to suggest it’s working normally according to Windows storage mngr. I have the OS along with several VM’s running off this drive along with hosting game servers. Has not missed a beat. I highly recommend this adapter card if you need it.

The fan coul be way more powerful and have a better design and the vent holes in the back could be a lot more open. RGB on it would be nice so it matches the rest of the junk in my PC these days.... The price is OK got it cuz it was the cheapest 1. I saw an RGB one but it was $100 more and thats dumb AF. Plugged it in and it worked right away.

The card does what it's meant to do and does it well... performance and cooling are both fantastic, throughput is excellent... all around great product with one substantial limitation that's really more of a fault with the chipsets/chips available than the card itself. In order to run all four channels on this card and actually use four nvme drives with it, it has to plugged in a full pci-e x16 slot with all 16 pci-e lanes... a physical pci-e x16 slot running x4 or x8 lanes will not only allow you to use one or two of the nvme ports on the card. Given that there are, to my knowledge, zero consumer motherboards available with two full pci-e 4.0 x16 slots running all 16 pci-e channels, you're essentially forced to choose between video card performance or drives. So, that all having been said, unless you're getting this to use on something like a Threaripper build with two full 16 lane pci-e 16x slots, you'll have to give up either video card performance or drive capacity.Ultimately, I returned the card and bought a motherboard with four on-board nvme slots to meet my needs without sacrificing video card performance but this would be a great product for builds, like x399 Threadripper systems, that support dual full bandwidth x16 slots so still giving it 4 stars

This is a very nice product. Very easy to use and works great. If you are using it with 4 NVMe SSD's make sure to allocate x16 lanes.

Card was easy to install and works great. Just never go the AORUS Storage Manager software working.

Only will work with certain asus motherboards

Easy to install, but mainboard bios needs bifurcation (pcie 4x4). Good value, ssd keep cold, silent fan.

Two HP EX950 2TB are installed on this adaptor. At first I did not know how to setup raid-0 nor raid-1; later I download Aorus Storage Manager and setup. Then with Disk Management I was able to create raid-0 and raid-1 and test the setup. The speed of the EX950 is excellent with raid-0. WIth CrystalDiskMark7, read/write speed of raid-0 is 6.91GB/s and 5.67GB/s respectively. The Raid-1 speed/write performance is 5.6GB/s and 3.1GB/s respectively.I give this adaptor a 4½ stars.
