Also, for the original question: for a home system, do you really need
the uptime  that RAID provides? I suspect not -- in that case, put
your money into backups, not RAID.

If it's a choice of good backups /or/ raid, go for the backups every time.  But if you have the money and space for both, then do both.  Raid is not just about uptime - it is also about avoiding the effort and inconvenience of rebuilding or reinstalling.

Hi John,

Personally I think you'd be fine with consumer grade drives. Put them
in a RAID-5 array and you should be set.

The high end consumer&  enterprise stuff w/ TLER and the like is only
really needed if you put a lot of demand on the disks, running virtual
machines for example. A basic file server for home use won't stress
the drives enough to need the more expensive ones.

Hi,

I've going to setup a _home_ file server to store all photos&  family
videos, work related material, DNLA streaming and more.

The server will be set to suspend when not in use for an hour or so.

I've been thinking about buying 3 x 3 TB SATA disks and put these in
software RAID5 (except for a smaller boot partition on all three disks
which will be RAID1).

Any recommendation for what SATA drives to get? Should I get
enterprise drives that support TLER (or alike), or will the greener
low cost drives be enough, is there something in between?

Is it better to buy 4 low cost drives in RAID1 or 3 enterprise drives in
RAID5?

Please help, I'm completely lost!
