Buying used SAS disks

[Octopuss]

What do you think? Good or bad idea? I've been thinking about slightly upgrading my home server's storage that runs on three basic WD Reds, and after ditching the idea of SSDs, which are simply way too expensive even 2nd hand in 2TB or larger capacities, SAS disks seems like the only other option.
Now Ebay is full of this stuff, but it's tricky category. Normally I would never buy used moving hardware, but I'm thinking, if I narrow my search to disks manufactured in the past five years, from sellers with lots of positive feedback, and possibly with info about the amount of hours on record, it shouldn't be a problem... Plus SAS disks should, theoretically, have much higher longevity than SATA.
I found one that sells 4TB Ultrastars 7K6000, 4kn, for around $40-50, which is just perfect.

What do you think?

maybe you could consider any warranty since 2nd stuff sometimes you have great stuff sometimes so so
if the condition looks ok and it has warranty, why not

Well it's used stuff, but there is DOA warranty. The seller is also on Ebay since 2009 and has 98.7% feedback in the last 12 months, so I guess it's credible one.

well at least the feedback is good, so maybe you could ask some information from the seller and how if after you run it for few days it drop, if the seller says it's ok just take it

Yep, I sent him a message asking about the number of hours on record. If he replies, it's another good indicator.

Generally not all that much problem with used SAS drives.
Mostly, harddrives are borked from the box. You may not notice that until you start using the drive and perhaps much later once you reach whatever area that may have been borked. Which is why the first thing you do is test a drive thoroughly. If it passes that test then chances are it will work for many many years.
So used SAS drives that already got a couple of years of work are generally going to last for a very long time since those that would have died early are dead and discarded already.
