If you are unable to mount the filesystem at all, then you can proceed with whatever tests you would like to try.
Based on what happened to your drive (and what appears to be happening to One-Hertz's drive) I suspect that is based on MWI exhaustion, not the physical exhaustion of the NAND. It’s a grey however area that manufacturers should confirm.

I am interested to see if/ how well the Samsung managed static data. One_Hertz, is this something you can determine?

@ Anvil, I monitored "normal" activity today using DiskMon and when I plugged in the stats it came out as 37% random/63% sequential for writes, with an average write file size of 64KB. Still not sure why ASU came out as mostly random. Will check into it more later.
