To RAID or not to RAID... that is the question!

post #1 of 7
Thread Starter 
Hey guys,

I've been waiting for the Asus P8P67 Pro board to come out for a while now, and it's given me a lot of time to go over and over (and over) the parts for my new build.

Right now I plan on getting this WD 1TB 7200 64MB Cache Drive. I guess my question is, without going over ~$100, is it possible to setup a quality RAID configuration? I take it I'd be getting two 640GB's or lower at that point?

I didn't even know what RAID was till 10 minutes ago... any details would be much appreciated (and rep'd!). I plan on using this rig for gaming and heavy 3D modeling. I'll be using the Carbonite internet backup system daily to make sure my data stays safe in the event of drive failure (hopefully carbonite supports RAID). Speaking of which... I mean, is RAID reliable these days?

I'm curious to hear about some of your setup's and suggestions. Maybe this "bright idea" is best left for a tier 2 upgrade for my new machine. In that case, the ~$100 budget doesn't matter so much.

*Sigh,* I think I've been starring at my newegg order page for too long

Well for under $100 it is possible to do a raid 0 config run through you motherboard's built in raid controller. This would increase the performance of your drives slightly. It would be a reliable setup, although not as high performing as if you had an expensive dedicated raid controller. It might be useful for 3d modeling, but for gaming raid is completely unnecessary. If you are going to be doing mostly gaming, I would recommend getting a larger hard drive over doing raid. If you really want to see a performance boost for your system, save up and get an ssd for an os boot drive.

some more info on raid 0

raid0 on the motherboard FTW (2xF3 500GB)

Mine flew in raid did like 212 Mb/s and sub 10ms access times.

But you will want to store files on a separate drive as raid0 have a higher fail chance.

Is Sata 6.0Gbps really even worth it yet? Right now that 1TB drive I'm looking at has that, while the F3's you mentioned are only 3Gbps. The cache size on the one I'm looking at is also 64mb. If it does matter, I guess this could wait. If it doesn't, then maybe I'll go with a RAID setup.

Well, it depends. SATA 6Gb/s is not worth running a single HDD on. If you start getting into RAID 0 configs with multiple HDDs or even single SSDs, SATA 6Gb/s will be worth looking into. I'm not 100% sure (but I'd bet) there is no single HDD out there that can saturate a SATA 3Gb/s connection.

EDIT: I looked up the fastest HDDs and alone they can not saturate SATA 3Gb/s. So like I said, unless you are going to go RAID0 (either now or in the future), don't bother with a more expensive drive with a SATA 6Gb/s interface.

EDIT2: The more I was just thinking about it. Even my C300 128GB SSD theoretically cant saturate SATA 3Gb/s (by itself). SATA 3Gb/s=384MB/s. Fastest I have seen my SSD do is 377MB/s, this was on a SATA 6Gb/s connection tho.

yeah realistically there are no drives on the current market that utilize the sata 6Gb/s speed at this time. Its pretty much just a marketing gimmick for the time being.

I kinda see it as a "race".

My Crucial 256GB C300 goes beyond the SATA2 specs so I bought an LSI SATA3 card to let it "breathe" and it does get better performance.

If I were going to stay with a single Crucial SSD, SATA2 would have been fine but I'll be purchasing another SSD for RAID0 and SATA2 will be woefully inadequate in that scenario.

All depends upon what you wanna do and when you wanna do it.

Naturally if you have SATA2 interfaces on your drives the whole point is moot.
