Hi

Anyway back to the topic (RAid 1 vs 5; write performance  and overall
performance for a file and print server with a hardware RAID card.)

I was aware of the need to calculate parity during the write in RAID 5 but I
thought the ability to write a small peice of the whole file to each disk (in
RAID 5) would be more significant timewise.

Does RAID 5 ever get better than RAID 1,  as you add disks?

ie RAID 1 vs   a  8  Disk RAID 5
is RAID 1 still better?
