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?

Cheers,

Phil.
