vb.org Archive - View Single Post - Which RAID setup & hard drives do you use, and why?

Ok..

Instead of doing a complex RAID 1 + stripping of the raid1 set, add a 5 disk RAID5 array of smaller 36G 15k drives. The great thing about raid 5 is the more spindles you add to the array the faster it'll get.

Going from 15k scsi to 10k serial ata would not be prudent. Cheaper yes but not faster, SCSI drive BIOS are configured for server type data paterns while desktop disks are not.

RAID10 while better than a 3 disk RAID5 array will not be better than a 5 disk array, and even a 6 disk array. Smaller faster (15k) drives will perform better than 10k serial ata. Make sure you have a good writeback cache on your controller as well, don't also forget to make sure you have the latest firmware/drivers for your array controller as well.

Also check into setting the stripe size correctly as well.
