So my recommendation if you want to go home brew is a Samsung PM981 m.2 drive and they can be found for $300 for 2T and less for 1T or 512GB. I used an SSK enclosure which is sleek but cooling is ok, I had an Intel 660p fail and not sure it was that case. Link is here SSK Aluminum M.2 NVME SSD Enclosure Adapter, USB 3.1 Gen 2 (10 Gbps) to NVME PCI-E M-Key Solid State Drive External Enclosure (Fits only NVMe PCIe 2242/2260/2280)
https://www.amazon.com/dp/B07MNFH1PX..._gK3zEbKMYNPD0 but I found this enclosure although larger to be better for cooling if you put it in the closed armrest SHINESTAR NVME Enclosure, Based on USB 3.1 Gen 2 (10 Gbps) to PCIe Gen 3 x2 Bridge chip, Include 2 USB Cables, Fit for Samsung 970/960 EVO/PRO/WD Black NVME SSD, Hot Swap, Plug and Play
https://www.amazon.com/dp/B07F9VQ4XC..._NL3zEbQB35571 but amazon says currently out of stock. I am sure there are others. I would buy this if you want something prebuilt as they never fail and are fast enough to copy lots of data to. Samsung (MU-PA1T0B/AM) T5 Portable SSD - 1TB - USB 3.1 External SSD , Black
