The Zheino 120GB SSD is nicely packed, includes a SATA cable, and seems to be good quality; but it has the worst performance of 12 brands (120GB-512GB SATA/M.2) I have installed and use, using ATTO for bench marking. Brand new, with no boot OS installed, the read/write performance is great, but even after an initial OS install its performance is completely erratic and it even shows in boot times. I've tried it on 3 different computers but it's always the same so I am not using it. Most SSDs deteriorate over time - see Seagate's document on SSD performance - but not immediately. This is the only one I've seen do so.
