Given the age of the USB drive, I figured it was worth replacing it with a new one for peace of mind. I wanted something with better-than-average reliability, but SLC or pSLC drives were a bit out of my budget. There's also a fairly limited selection of industrial/embedded drives that can be easily sourced, at least here in Canada. I was able to find this Transcend JetFlash 270M for a reasonable price (although still expensive per GB, of course). It's an industrial drive with MLC, and specifically states it has ECC -- I think this isn't uncommon, even in consumer drives, but it seems rare to have it explicitly stated. It also has a TBW rating, for the 8GB drive it's rated for 8 TBW, so 8000 full writes. That's a fairly low TBW rating compared to some other industrial drives, but still should be sufficient for many years of use. Unfortunately the drive info was unable to identify the controller or the memory, but I did find a datasheet that suggested it may be using 16nm Samsung MLC chips. I'm not sure that this is actually any better/more reliable than Transcend's consumer MLC drives like the JetFlash 780, but as the price was acceptable I figured I'd give it a go. I've not swapped Unraid over to it yet, but the USB installer suggests it has a unique GUID, so I'm not expecting any problems.
