There is no justification. As a technologist it's easy to drool while looking in the Great Deals section. I combat it by thinking to myself that when I really do need to upgrade drives there will be better deals (cheaper for greater capacity) available...so my wallet slips back into my pocket.guess it should be ok for light duty consumer use or boot drive use. but i probably won't put them back into extensive server use again.
I guess the question for me who doesn't run servers that needs a lot of fast i/o is what is the justification for upgrade from my spin hhd for just routine storage. probably none? i am still using even just a 32gb msata module as a boot device on my levono d30. and i still have a couple of 120gb ssd spares to play with....
I could justify to myself for the upgrade to all ssd for reliability from my array of 9 independent non raid hdd. The problem is that the cost/gb is still too high. I use it more in a storage capacity rather than high i/o scenario so the high i/o advantage of ssd is not needed. but i still like the higher reliability of ssd but cost is still too high ;(There is no justification.

I think the only way to handle is to leave negative feedback with comment why, unless you want to encourage the ebay scammers of course. There is nothing wrong with selling used drives , as long as you sell them as used, otherwise it's a scam big time.Answer to self; After reading the article (love this site) http://www.servethehome.com/used-enterprise-ssds-dissecting-our-production-ssd-population/, it does seem reasonable with 143TBW (WLC*480GB) during its time in a DC. (Division by 0.96 was just a brain fart.)
Seller offered a full refund (insisting that the drives are brand new and manufacturer sealed), but I'm keeping the disks anyway. Made a point that he should change from 'new other' to 'used' and that the price should perhaps be $80ish. I'm rather new in this game and curious how to handle this kind of sellers. Suggestions?

Firmware could have been updated at a later date. The one printed on the drive is the one it shipped with....
Something else that seems a bit off is that the firmware doesn't match. The firmware on the SSD is DXM87W3Q, but both hdparm and smartmontools report the firmware as NS00. Additionally, the SSD isn't recognized by Samsung Magician DC v1 (i.e. the Linux command line / enterprise version of Samsung Magician). The documentation for Samsung Magician DC v1 explicitly specifies that the SM843T is supported. It also specifies the SM843T as "limited support - cannot update firmware," so I'm not sure what the deal is here. ...
Just to clarify, I'm referring to the first release of the enterprise / datacenter version of Samsung Magician (Samsung Magician DC), which is a command-line tool for Linux only (not the consumer GUI version). I checked Samsung's website, and it looks like this links for this initial release are no longer active (the version they currently have up is the second / V2 release, which I believe is for the PM863 / SM863).Firmware could have been updated at a later date. The one printed on the drive is the one it shipped with.
Regarding Magician not working -- it'll only work with non-OEM Samsung drives. Don't quote me on this, but I think part numbers ending with 00003 are non-OEM Samsung drives. I have two PM863s with part numbers ending with 00003 and DC Magician works fine. Drives with part numbers ending with 000G3 are HP OEM drives and DC Magician does not recognize them. These would also have their own custom firmware, not the one shipped with genuine Samsung drives, so it's not surprising that some SMART attributes may not be supported.
Interesting. I was going by what I saw in one of the pics where the drive is shown with a part number ending with 000G3. If the one you received is a 00003 then I have no other theories as to why Magician doesn't work.... My SM843T does have a part number ending in 00003 (as well as my SV843), and doesn't have any 3rd party indications.
Still worth milking the seller for a partial refund even if you want to keep the drives, that is some shady business practice.I got 10 myself, they were all zipped up in new anti-static bags but not had time to take them out and play with them.
I guess as long as they have decent life left in them and perform ok then still a decent deal, but very misleading selling them as "NEW"
