I have a small server at home (HP Proliant Micro N36) that I use
for file, DNS, DHCP, etc. services. I currently have a zpool of four
mirrored 1 TB Seagate ES2 SATA drives. Well, it was a zpool of four
until last night when one of the drives died. ZFS did it''s job and all
the data is still OK.
The drive is still under warranty and is going back to Seagate,
but it raised an issue. I want to pick up a spare drive or two so that
I don''t have to wait for shipping delays when a drive fails. I was
just going to pick up another 1 TB ES2 or two, but I find that those
drives are no longer available (I bought mine in 2009, warranty is up
in 2014).
What do people like today for 7x24 operation SATA drives? I am
willing to consider 2TB, but don''t really need the extra capacity (but
if that is all the market offers, I don''t have to use the other half
:-) I found a Seagate Constellation ES 2 TB for about $350 (which is
more than I really want to spend, I got the ES2 1TB drives for about
$130 when I bought them). I have been sticking with Seagate as I am
comfortable with them, but am willing to look at others. The only
thing I insist on is that the drive be rated for 7x24 operation.
Thanks, in advance for all of your informed opinions.
P.S. I am sending this to TWO lists, please do NOT respond to the list
you are NOT subscribed to :-)

They''re quiet and they only draw about 70 Watts (each, of course ;) ). The drives I am using are Hitachi HUAs 72202 (Ultrastar 2TB), 2 mirrored vdevs, providing 3,6 TB. They are still kinda pricy, but I do have a lot of them running at work and they rarely gave me trouble. There are a couple of Hitachi Deskstar drives, that I would be tempted to try out, since they are tagged as 24/7 and they seem to be much cheaper, but then I am always trying to figure out why these drives are only 60% of the HUA''s price and and what if that''d be for a reason.

I still have a set of 10 regular Seagate drives I bought in 2007 that were spinning non stop for four years in a very hostile environment (my garage!). They simply refuse to die and I''m still using them in various test systems. -- Ian.

Lately I''ve been having better luck with my 500 GB WD Blue drives, while in two systems I have recently replaced dying Segate 500 GB drives (7200.11) from 2009. One was part of a ZFS mirror, and the other a Linux mdraid mirror. The drive in the OI box had a very large number of reallocated sectors and finally showed a bad SMART status (but no ZFS checksum errors on scrub). The drive in the Linux system started throwing read errors, yet had few reallocated sectors and still showed "PASSED" in the SMART data. Worse, it FAILED to reallocate sectors! If you''re running 2009-vintage 7200.11 Barracudas, be prepared to replace them soon if you haven''t already done so.

I would take a look at Hitachi, since that''s what Sun put in my x4540. I''ve also had some luck with the samsungs. One interesting thing I saw (I have 4x3TB samsungs and 3x 3TB seagates in one zfs pool) is that the SMART counters climb very fast for 2 or 3 of the counters. I don''t recall which offhand, but if you have a chance, I''d like to validate if it''s my drive, or if it''s normal.
