<div dir="ltr">Thanks, I was leaning toward giving the Red NAS
drives a shot, but went with two WD Blue drives, they were on
sale really cheap. I noticed some manufacturers don't even make
1 TB anymore, which is actually what I'd prefer to stick with.
RAID drives with 3 - 4 TB give me the impression there is a
little more room for failure on a RAID, that, and it's more than
I need.

<div>I've used green drives when handed them to me at a previous
job for a NAS, they actually did okay for about a year of
large (images) being archived on them, then one of four
started relocating sectors like crazy. I wouldn't rule the
greens out with spares on hand for a home NAS.

<div>I've seen the studies about Seagate. I must of lucked out
before they went south, the first two I have still have
their 5 year warranty and no issues popping up in SMART yet
(I think they are about 4 years old now). </div>

<div>Backing up the old raid to an external. With the amount
of backups I have, if I do decide to try zfs before the
sticking with a Linux software raid I'll post the experience
here. </div>

I would recommend buying at least 1 extra drive per array,
so you have a hot-spare.

Based on the pile of dead drives laying on my desk
right now (and the links below), avoid Seagate like
the plague. Unless you really like swapping disks all
the time.<br>
I tried out a WD "Green" drive for an application
where performance didn't matter as well (offline
storage in a fire safe, with monthly updates), because<br>
it was cheap - and it was junk too. It literally
worked 3 times, before failed entirely.<br>
<br>
Higher end WD is probably better - but lately, I've
been spending the extra $ for Hitachi / HGST drives
for systems where I don't want to deal with drive
failures:<br>

<br>
WD now owns the Hitachi drive line, but they don't
seem to have ruined it yet.<br>
<br>
As far as disk size... 2 or 3 TB isn't that much
higher than 1 TB these days.... especially if you go
with the cheapest drives, and just deal with the
inevitable failures.<br>
<br>
Depending on how the numbers shake out, however, you
might come out ahead just running 3 6TB drives in a
mirror config, rather than 5 smaller drives in a
different RAID config to get your 2 drive
fail-safety. Another nice aspect of a simple mirror
setup, is you can pull a drive and read it, without
needing the RAID config.<br>
