Bought this kingston xs2000 a while ago. It's officially rated for "up to" 2000Mb\s read\write but slows to a crawl after 30GB have been copied. Fyi, I'm copying files from an internal nvme (samsung 980 pro) via a usb 3.0 cable, so this kingston ssd is the only bottleneck.
TLC flash and no DRAM will do that. ๐ข
What's another better option for this use case, that you would look at?
Check reviews that test writes over ~15 minutes. This kingston holds out the longest but then has a very low floor https://cdn.mos.cms.futurecdn.net/cqJ6pXctEd5BKJVLJN7TCD-1200-80.png
It's a worst case senario for all drives though, and they will drop in throughtput. Caches run out, heat build up, power supply gets strained, it's rough.
