Recently Dell is selling their WD20EARS (2TB) for 90$
This being one of the best PPG (Price Per Gigabyte) snatches I have
seen, I was considering buying 8 of them for an mdadm array.
Has anyone had experience with these drives?
Note, they have 4K sectors.
Thank you for your kind responses.

This is a low-cost consumer disk that is rated for a whole 2400 hours
use in a year. You get what you pay for.
I think the "I" in RAID stands for inexpensive :-P
Jokes apart, don't you think frequent scrubbing (e.g. weekly for a
raid-6 or 2/week for raid-1/10) is enough to compensate for this?
I would be way more concerned with ERC / TLER if it proves to be
nonsettable, but I might be wrong
