RAID 0 or RAID5?

post #1 of 21
Thread Starter 
Hey,

So I'm planning on getting a bunch of those WD 640GB drives and putting them in a RAID config in my new build. I'm not going to put any real important stuff on the drives (anything important will go on my private server or DVDs), but I'd hate to have to re-rip my collection of DVDs and music in case of a RAID0 failure.

How much space will I have if I go with a RAID5 array? I assume I won't get the full 4x640GB because of the parity it provides, but I've been wrong before.

Thanks guys

~Gooda~

If you want to RAID 0+1 you'll have about 1.2TB and you'll be all backed up so no reripping.

If its not for fault tolerence i think you should not go with the raid. idk if its really a big step over the sata speeds these days.

If you keep a fairly current system image and a drive happens to fail it takes litereally minutes to recover. I think its the way to go save some Jing, your gonna keep everything important off them anyway just my .02

I thought RAID0+1 used one drive for parity? So in theory I should lose 640GB? I guess I answered my own question there if I'm right.

When I said I didn't want to re-rip my collection, I was referring to the RAID0 array, but thanks anyways

It will be about 600GB+600GB(+-) =1200GB and you'll need 1200 GB back up for 0+1.

raid 5= 1.9TB
raid 0= 2.5TB

If a drive fails
raid 5 = you buy a new hd and it will repair it self
raid 0 = all data gone.

My drives show massive improvement in RAID 0.
I have three of these with 2 in RAID 0 and one not. The RAID array pretty much halves I/O times. I'd post benchmarks, but I'm out of town atm.

I'd suggest RAID 0, and just make sure the drives are cooled and run hardware checks every once in awhile or as soon as anything funky happens. But then again, I use a secondary drive for all my data storage.
