NAS Units

Ok I am now broke. Anyone want to buy some domains!

Bought the Synology 1513+ (5 bay) and 5 x 4tb Deskstars (and a camera to keep my other half from giving me grief about spending so much... )

I loaded in the drives already and am now figuring out the bast RAID config. I thought because these drives are reviewed as more reliable that RAID 5 would be ok, leaving me with more available space... then I read that if a disk fails and I'm rebuilding, that's the time when another disk is most likely to fail! So RAID 6?? but then lose half the capacity?

I also read about the huge amount of time for rebuilds with 5 and especially 6... so RAID 1 and mirroring? Too many decisions... my gut is saying RAID 5.

If you are using a local USB backup incrementing a few times a week, then Raid 5 should be ok, worse case if you get a failure during a rebuild (2nd drive death) you lose a few days at worse.

Raid 5 should give you 16tb and raid 6 gives 12tb so not really half the loss, just additional 4tb.

If you're not using a local usb back up, then prob raid 6 is best bet.

Edit: with the 1513 you can add the 2 or 5 bay expansion unit as well, taking it up to 10 bays, so raid 6 may well be better with a long term view.

Looks like you made a good choice on the 4tb Deskstars Steven ...

Backblaze just released stats on the reliability of the thousands of drives they have in their storagepods. Makes pretty interesting reading, definitely won't be buying smaller Seagate drives after reading this!

Hitachi are destroying the chart, and Seagate has a shocking report on there.

I can vouch for Samsung's their F4 drives are awesome in backup device, I have a bunch of them running for backups. they only have a bunch in there so didn't really report much.
