I can recommend SW raid in a production env. We have two
samba servers that have been running software raid for over a year
with no problems at all.
One is running raid 0 for speed/size reasons and the other is
running 5 for reliability. Unfortunately this period includes no actual
disk trouble (other than simulated) so in a real failure your mileage
may vary.
As for speed I suspect SW raid is faster than HW raid for a given
price point. I'd expect x86 MIPS to be much much cheaper than
dedicated controller MIPS. Instead of buying a HW RAID soln go
with SW and throw the saved money into /CPU/memory/disk
improvements and be happy.
Cheers
Rod
