Motherboard: GIGABYTE B450 I AORUS PRO Wi-Fi (AMD Ryzen AM4/Mini ITX/M.2 Thermal Guard with Onboard Wi-Fi/HDMI/DP/USB 3.1 Gen 2/Motherboard)

Drive: Samsung (MZ-V7E500BW) 970 EVO SSD 500GB - M.2 NVMe Interface Internal Solid State Drive with V-NAND Technology, Black/Red

Using this M2 enclosure

As you can see, one of the only 3 reviews says he is getting over 1000MB/s from his setup. He's using USB 3.1 with Thunderbolt. However, the USB 3.1 Gen 2 spec I have on my board has a transfer rate, after deducting overhead, of over 1200MB/s

I have the same drive in my rig and I get max read writes with Crystal.

Anyone have any ideas?

The problem was the cable that came with the enclosure. The vendor said it was USB 3.1 gen 2 cable, but clearly it wasn't. I tested it with a true gen 2 cable and got near gen2 max speeds. Anyway, they said they didn't have anymroe cables in stock so they were sending me out a new enclosure for free. Who does that except Amazon vendors?
