well some interesting / bad news (possibly bad).

While the 21x of these drives i got have been running great, there does seem to be a pretty serious bug / issue with quite a few of them (or maybe with their specific HP firmware).

When i run a SMART LONG test, towards the end of the test, the drive FREEZES or drops out (but comes back), or something that will cause freenas to throw errors (or possibly break your zfs pool). I have only been able to test this on maybe 4x of the drives, but all ive tested, have done it. Running a Short smart test, executes fine / no problems.

now i happen to be lucky when this first happened, and my pool (2x vDEVs of 5x SSDs in Z1) just threw some nasty errors (but all data seemed to be fine + resilver clean) (i rebuilt the pool as 2x Z2 vDEVs like i should have from start),

Also in testing these same drives solo, on a windows box (no raid, just a LSI HBA), i was able to repeat the issue.

Outside of this bad/dangerous smart test issue, these 21x drives have been flawless (and ive been running them hard).

SO PLEASE BE CAREFUL IF YOU RUN LONG smart tests on these 480gb ssd drives!

(weird thing is, on some of the drives, early on in their life, someone was able to successfully complete long smart tests. now im not sure if they were running a different FW at that point, or what, but see bottom. also there are a few that dont seem to have this issue, but im scared to re-test them until i have some spares)

from a seperate machine, where i made sure r/w load was constantly applied to drive during its smart test (idea i read on a mailing list, that did not resolve this):
