Need your guys opinions!

post #1 of 5
Thread Starter 
So Im going to Raid my system very soon here. Really the last thing I have to do to it yet. Now, my original plan is to have 4x 1.5TB hdd's and 4x 2.0TB hdd's. I was going to run them both in raid 5. Do you think it would be better for me to run the 1.5's in a raid 1+0 since these are where I am going to run the OS off of? Let me know what you guys would do so I can get some ideas.

Also, what Raid Controller would you go with? Do I run one set of disc off the built in raid setup on the mobo and the other of the controller? Or just run everything off of a really good controller? Thanks!

You probably already know what you're dealing with...but here's a decent explanation about RAID-10/0+1 from DuckieHo...

If a single disk in a RAID10 fails, it becomes almost a RAID1.... It can substain another disk failure if the disk is part of the other stripe.

If a single disk in a RAID0+1 fails, it becomes basically a RAID0.... It cannot substain another disk failure.

RAID5/6 take a hit on random access and writes since there is overhead for the parity calculations.

For file storage use (write once, read many), RAID5/6 is great. A 4 disk RAID5 provides the storage of 3 disks and sequential read performance close to that of 3xRAID0.

A 4 disk RAID6 is provides the storage of 2 disks and sequential read performance close to that of 2xRAID0. The benefit of RAID6 over RAID10/0+1 is that it can always substain two disk failures.
Basically you shouldn't run your OS drive off a RAID-5/6 as that type of RAID is more used for storage/servers. However, your take on setting up your OS on a RAID-10/0+1 might be a better decision if you want to have striping/mirroring for your main OS drive. Depending on the situation...it's up to you to decide whether you want RAID-10 or RAID-0+1 as that type of RAID is hard to explain. Look up Nested RAID levels on Wikipedia for more info on that.

Best controllers for the price to look for are the PERC 5i/6i which is what many OCN members look into. Otherwise be prepared to spend the big bucks for brands like LSI, Adaptec, or Areca (what I personally use). If you can find one of those controllers used like I did, then I'd say go for it since they are much cheaper that way. Specifically what to get is up to you whether you want to deal with SATA or SAS, the brand that may be more better in terms of experience, or what slot you will put it in (PCI-X/PCI-E/PCI).

if you don't have the drives, you'd be better off with a small (60GB) SSD for your OS, 2x1TB F3s for extra apps etc in RAID0 with a second RAID1 array for backups (using Matrix RAID). Then add your remaining 4x2TB for your data.

MUCH better performance all round for similar money.
