This is the adapter I have used for my last 31 builds since 2016, purchase them from china. They have had a little crud on them but nothing like that.
I keep up with most of the people I sold them to and all I know of are still working. 3 of my own Xboxes are used regularly and have had no issue. I have also used them for custom arcade cabinet builds and those 6 still work fine, and have very fast boot and load times.
A lot of them have issues right from the start though, about 25% of the boards I bought did not work. I use a 200GB SATA hard drive for testing before connecting them to a good drive. None have ruined my test hard drive yet.
It seems like if they work fine, they will keep working. but with only 3 years using one regularly I just don't know. If mine did not work I could not get them working. I removed the junk solder from the joints at the connectors, and reflowed 90% of the board to see if I could bring them back, but no go! All 5 I tried to revive stayed dead, although the boards now look pretty.
I will be testing speed times for boot and game loads soon. I will compare this same board to a Sabrent.
