Best RAID Setup for 3 or 4 Drives?

post #1 of 6
Thread Starter 
So I have 3 Seagate Barracuda 1tb drives and 1 WD (green) drive. I have two of the Seagates in raid right now. I was considering putting all 4 in a RAID configuration. I have an SSD for OS so no OS on this config. I want max performance that is possible with redundancy.(i know redundancy will hurt my overall maximum possible performance and total storage) My questions are:

1) best RAID config with my current drives?
2) Will the one "Green" drive hurt me or prevent me from any setup"
3) How do I get Windows to recognize larger than a 2tb partition?
4) Should I get a PCI Raid controller?
4) Anything else I should know?
5) Should I add another 1tb Seagate?

NOTE: I do have a need for all the storage.

Thanks guys.

Using an onboard RAID controller? I would say RAID 10.

10 for best performance with onboard.
You could run 5 and regain the capacity of one drive, but you'll be penalized on writes due to parity.

Also, an array will always be gimped to the speed of the slowest drive.

Seriously, I would NOT string that Green drive with the three Seagates, it'll hurt your performance. I think your best bet right now would be to either

a) a RAID 5 with the three Seagates or

b) buy another Seagate and go RAID 10.

Since it sounds like you need the capacity, I'd say go RAID 5 with the Seagates. The latest Intel RST drivers support capacity expansion, so you can always go buy another Seagate and add it to the RAID later. Write performance won't be great (actually it'll be crap) but if it's just for storage, it won't matter.

To get Windows to see a volume greater than 2.19TiB, you must ensure that the volume is partitioned GPT, not MBR.

One last thing. According to what I have read, the ICH10R's RAID 5 implementation needs TLER enabled on the drives, in order to avoid kicking them out of the array when they hit a bad sector. Luckily, Seagate support this on their desktop drives (they call it ERC). Look here for a discussion on it.
