So basically a 2TB NAS if you're sensible
am I right in saying these use seagate barracudas? click of death
Good price for a redundant 2tb NAS.
very good price me thinks if this includes the 2 drives

So a mirror ?

What happens if both disks die? unlikely but if there's a power surge it can happen.

I would rather have a stripe raid 0 and back it up to an external disk. Much safer.

If both disks die, you would resort to your backups as normal.
so then if you backup as normal isn't it better to have 4TB ?
we should all backup. sadly some people think RAID = backup. Then they learn the hard way heheh

No, I'd rather have RAID and backups. You're more likely to have just one drive die (or just small bits of it that become unreadable), and that affords you the opportunity of being able to just swap the disk without any time or effort. The convenience is well worth it.

On the other hand, without RAID, any kind of failure means you have to resort to a backup, which invariably means that you will lose some data (depends how old the backups are), plus you then have to spend the best part of a day restoring everything from the backup, during which period you can't access all of the data properly. Plus you'd have to wait a day or whatever for the replacement disk to be posted to you, whereas you can continue using the RAIDed volume (using its single good disk) while the replacement is on its way.
... until you get the URE when rebuilding a RAID.... I'd rather have 4TB AND backups (which is what I was suggesting) but each unto his own...

I'm of the same opinion. People don't think the NAS controller board will ever fail. when it does, their RAIDed drives won't be very accessible.

However, I couldn't really care less how other people preserve their data, they all have their own ideas and they all seem peculiarly certain that their way is the right way. I'm as guilty of it as the next person.

It is worth checking your nas uses a standard disk format before relying on it.

So what is your preferred medium to back up all your data?
