Raid 1 or Raid 10?

post #1 of 2
Thread Starter 
I am using a QNAP 4 bay box, and do NOT want to lose data. I currently have 2 Hitachi coolspin 3TB's, and am picking up 3 more tomorrow (so I have a spare on hand in case of drama). I will be doing manual backups every now and then unless I can find a way of setting up auto backups via esata on the QNAP box.

6TB is fine for the moment, and yes I've read the sticky here, and http://en.wikipedia.org/wiki/RAID , but I haven't seen anywhere that says I can take 4 drives and make 2 pairs of raid 1's into a single volume.

Question is, can I combine 4 3tb discs into 1 6tb volume that will lose no data if a single disc dies using raid 1, or do I need to choose raid 10?

OK,

I would personally go with a 3 disk RAID5 array with a hot spare.

Basically, when a disk fails, it'll build onto your hot spare disk. You can then remove the failed disk and put a new one in the array. It's very good for redunancy. You'll have 8.38GB of usable space.
