[lug] NAS - OpenNAS, FreeNAS, NAS4Free, or COTS?

[Quentin Hartman]

I have to just put in a plug for a Synology device. They are pretty well
bullet proof and super easy to maintain. If you need to do anything weird
they are linux based, but out of the box they are very capable. They are
more expensive up front than rolling your own, but inexpensive enough that
the difference is more than made up for by the time savings in most cases.
I have a couple at the office, and use one for general NAS / file sharing
stuff, and the other as a backup destination. They are great.

also re RAID-5, in my experience, most of the problems with RAID-5 are
largely theoretical, until you get up to raid sets with about 10 disks or
more. I've never had problems with sets smaller than that, in terms
performance, reliability, or recovery time. If budget is a concern, and you
are using a 4-5 disk array, RAID-5 with a single hot spare (or even without
if the data is reconstruct-able and an array failure would be annoying but
not catastrophic)  makes a lot of sense in my opinion.
