[kwlug-disc] Cheap disks for storage upgrade

[Colin Mackay]

Personally, I use refurbished SAS disks from eBay.  I purchsed 10 Helios
8TB disks for my TrueNAS upgrade a year ago.  8 installed, 2 cold spares.
They usually ship with thousands of hours of runtime, but the MTBF (Mean
Time Between Failures) is in the millions of hours.  They're designed to
just keep running.  Mine are listed as 2.5 million hours.  Yes, take this
number with a grain of salt; this is theoretical; it's a calculation based
on how many drives failed over a time period.  This is why I purchas two
spares.  It gives me time to order another while the spare drive resilvers.

The advantage is they tend to be 50% - 80% cheaper, depending on the seller
and market...  I got mine for just under $100CAD each.  $14.99 shipping for
the lot.
