Hi All, I have just read a slide from the U2 University sessions whereby it states...
RAID 0+1 is absolutely the fastest implementation possible for disk drives t>Internal and External Disk Drives -Raid 0+1, striping and mirroring tWhen a mirrored disk drive is not committed to a WRITE, it is available for a READ tAdditional throughput from RAID 0+1 is about 40% tParity WRITEs never are in contention with the production disk drives. RAID 5 will have a parity WRITE be in conflict with the Production Disk Drives tHW level RAID implementation is far better than SW striping and HW mirroring tStripe size was 128K. Any larger, and a file can be on a singledisk drive. Can anyone tell me how it compares performance wise through theory or experience to RAID 10 which as a configuration is more fault tolerant and easier to rebuild?
