Dumb Raid question
I just setup two WD 80 gig drives in raid 0. My question is that in raid 0 [stripping] I thought I would only “See” 80 gig, however I am seeing the combined capacity of the two drives ie approximately 147 gig.
Everything is working great; there has been a noticeable increase in performance with the raid setup. I am just wondering about the capacity of the array and why I am seeing more than 80 gig. |

The RAID 0 array is considered by the BIOS to be one drive, and the system writes half of the data to one drive and half to the other at the same time. The array combines the true capacities of the two drives.

Thanks, I thought I might have had it backwards. So if I created the array with raid 1, then I would see only 80 gig?

Yeah. You would only have 80 gigs of space, because, in that setup, the second drive is being written to exactly as the first one (mirrored), for backup purposes. If one fails, you don't lose any data.

yes if you want to change from raid 0 to raid 1 then the info on your hard drives will become damaged as half of each file is on each hard drive if you have another drive on the ide of the mother board copy your data to that first using drive image or gost

The optimal and safest RAID 0 setup is to put your data and programs on the RAID array (for speed) and use a third HD on the mobo IDE controller for the OS and data backup (to provide a degree of redundancy).

I use a third hd to backup things like quicken, music, etc. The performance increase with the raid is amazing; everything just seems quicker. What impresses me is that I had a WD80 8 meg drive to start with. Using two really makes things move.
I am very pleased with the highpoint rocketraid133 card. |
