non Raid vs Raid 0 Stripe hard drives?

Question

From what I understand, a non raid hard drive has normal performance speed. And a Raid 0 configuration supposedly has faster performance. With a Raid 0 configuration, do you use both hard drives or one at a time and can you use one as a back up? I hear that Raid 0 has more chance of failure and if one drive fails the other fails as well. Which one would be better to get?

I am looking at these two.

Hard Drive 1TB NCQ SATA (2x500GB) 7200Rpm Dual HDD Config Raid 0 Stripe

Hard Drive 750 GB Serial ATA non Raid (7200 Rpm)

Answer 1

Raid 0 is a "striping" arrangement where half your data is written to one drive and half to the other. If either drive fails, your data is gone. The advantage is that you can read/write from alternate disks and since you don't waste as much time waiting for the disks, it's faster. Unless you're accessing large amounts of data on the disk all the time, I wouldn't bother with it.

Answer 2

You can run a striped, mirrored pair, but you would need four hard drives for this.



You then get performance and redundancy, this is supposed to be popular with extreme gamers/system tuners but I would wager the gains are negligible for most home computing requirements.

Answer 3

yes ,,,2 x 500gb in raid yes ,,,you will lose data if one fails no ....you cannot partition
