NVME Adapter PCIe x16 with Heat Sink, M.2 SSD Key M to PCI Express Expansion Card, Support PCIe x4 x8 x16 Slot, Support 2230 2242 2260 2280, Compatible for Windows XP / 7/8 / 10

I was a little nervous at the idea of putting my NVMe in an adapter - but my motherboard only has space for one on board and that was already taken, but I wanted to add a larger second NVMe drive. It was very easy to put the drive inside this adapter and the performance was actually higher than I was expecting! So if you have a situation where you want NVMe performance, but don't have an available slot - this is a perfect solution.

Not much too these little adapters and over read reviews where people say the cheapest one work the same and the most expensive ones. This one liked exactly like some of the more expensive ones and I bet they are made at the same factory in China. It came with extra screws and a little screwdriver. It comes with the heat sync closed and the little screws were really tight but of you press really hard you should not strip them out, just be careful.

I really like the simplicity and look of this adapter, along with the cheap price. Probably the cheapest you are going to find. On top of it being delivered VERY quickly (Within 2 days). As far as the technical details, I got the full speed of my m.2 NVME drive (It was a WD BLUE SN550). Remember that m.2 NVME drives require 4 data lanes to operate at full speed (4x, which is good for compatibility as almost all motherboards, even older ones, can support this), and also an 8x or 16x PCI-e slot is NOT going to give you more speed... This is a very big misconception I see people review and complain about the product when it just does NOT work like that. Your device is only as fast as it operates. It is like complaining that your mechanical 5000RPM HDD doesn't run as fast as your SSD (And they use the same SATA interface). The only thing an x8 or x16 lane can offer is if it can do bifurcation, then you could run x2 NVME drives on an x8, and x4 on an x16 lane. Your motherboard has to support that. (Google and learn before going all out). I knocked off a star because it was commented that this board did NOT have LEDs (Which is why I chose this one). It does in fact have FOUR bright blue LEDs that indicate the drive read/write. I do not like this for cosmetic purposes, and I could complain that it is a little energy waste... The heat-sink that it comes with does cover them, but I wanted to use it without the heatsink. It also did not come with any instructions, and any information is hard to find online (Although it is pretty straightforward if you consider yourself tech-savvy with this). Besides that; it's cheap and affordable, low-profile/small, looks decent, packaged well, and gets the job done.

Installed this in my Mac Pro Tower 4,1 (flashed to 5,1) and using a 1TB ADATA XPG SC8200 Pro NVMe SSD as a Boot Drive running Mojave with a Radeon RX-580 Graphics Card. Some initial instability, but now apears to be rock solid once I reseated the adapter in the second (16x) slot. As with my previous OWC SATA 3 PCIe card, I had to put a small felt spacer between it and the graphics card to provide enough clearance for the RX 580 fan to spin freely. Not as fast as this NVMe card could actually go, but still 3 times the read speed of the SATA 3 SSD I had in it and over 10x the write speed at ~1500MBps on both due to limitations of PCIe 2.0 4x interface - whereas a bridged card would be required to max out this particular NVMe card speed of ~3000MBps on these Macs on the PCIe 2.0 16x lane slot.

Used this upgrade my sons hard drive with a 1TB nvme M.2 and booted up without issues. Easy to install or remove and handles gaming no problem. Highly recommended
