Curious what you guys are using for your SAS/SATA enterprise SSD purchases. The SATA ones are easy as I just hook them up to my windows testbed and use HDsentinal Pro but on linux im unsure of how to gauge health properly. Unfortunately a number of these drives have their SMART data wiped by eBay sellers....

Are you guys using badblocks on SAS SSD's or is their some other app to gauge health?

Which SSD & seller @bash are you getting with SMART data whiped? I've purchased probably close to 6 dozen in the last 15mo now and I've seen 0 with SMART gone. Sure I've gotten a handful that didn't work, mostly being older drives (SAS and SATA) but never once have any drives had missing SMART data.

I'm not sure i'd trust anything without smart data, as for testing them a heavy read/write load in a raid array has been what i've used in the past, if a drive gets kicked out of the array it's no good.

I have to SSH into my linux test bench from work but here is the "smartctl -a /dev/sdh"

that output looks odd. maybe it's normal for the drive, I don't have one so I can't say. are you using some kind of enclosure/translator that might be screwing up the smart queries?

I know when flashing certain micron drives I have blown away the smart data... soo... It is possible.

Norco 4224 Case that has the SAS backplate
Norco SAS Backplate <-RES2SV240 <- M1015(IT mode)

Have not had any issues in the past with the above setup.

this is typical SAS SMART info

this seems all data has been zeroed (or nothing error logs?)

Error counter log:
Errors Corrected by Total Correction Gigabytes Total
ECC rereads/ errors algorithm processed uncorrected
fast | delayed rewrites corrected invocations [10^9 bytes] errors
read: 0 0 0 0 0 0.000 0
write: 0 0 0 0 0 0.000 0

watch out on "Total uncorrected errors", it the number grown-up rapdily, you know what you have to do...

that is normal for SAS drive, since SAS has more/complete internal control than SATA(simple aka dummy).....

I have been buying used SSD SATA drives for awhile and once they pass my usual QA routine I have never had an issue. I wanted to jump into the SAS space after reading @Patrick buying guide.

I think the issue with the Optimus drive is the firmware is just screwed. I know this seller sells allot of drives with custom firmware perhaps they attempted to flash the drive BACK to the manufacturer firmware and screwed it up.
