Basic question from the semi-ignorant; are all HARDWARE RAID cards 64-bit? And other RAID questions.

"Oh, also, what's the diff b/t RAID 0+1 (I know what that is) and RAID 10?"

As UCLA88 said, RAID 10 is a stripe of a mirror where RAID 0+1 is a mirror of a stripe. From a capabilities standpoint, RAID 10 is potentially more fault taulterant. Since 0+1 is a stripe with a second stripe containing the exact same data, if you lose any one drive, all you are left with is a single RAID 0 array. If you lose another drive, your data is gone. With RAID 10 you can potentially lose multiple drives and still have all your data intact.

"Are the 3Ware 6400 and 6410's hardware raid cards?"

They are RAID 0 and 1 hardware controllers. RAID 5 is done through a software driver.

The 6400 is a full length PCI card, while the 6410 is a half length. I don't think the 6400 is produced anymore by 3ware.

"2. Will the performance of these "low end" hardware raid cards be significantly better than the RAID0 from my onboard software raid on my KT7R mobo?"

In a 2 drive array, not really. As you add more drives, the hardware implementations will perform quite a bit better.

ATA 66/100 doesn't matter, especially with the 3ware cards that are limited to one drive per channel. It will be a long time before ATA drives break past 60MB/s. That said, the 7410 is a better card that will perform at least marginally better than the 6410 is most situations.

did u read the review at storagereview.com? the 7410 has problems with raid 5

also it isnt really any faster than the 6410 and it cost $100 more..

Thanks Pariah and Q & A. I am more educated now, but still undecided as to what to get. I really wasn't considering having more than two drives in the "0" stripe...I want to do either a 3-drive raid 5 or 4-drive raid 0+1 or raid 10. I think I need to do some more reading as I'm not even close, knowledge-wise to what you guys know. Thanks very much. Thumbs up for you guys!
