i can swear by Linux software RAID 100%...
although the majority of my experience is with RAID-1 mirrors...
(and an occasional RAID-5 set...)
it has saved my systems several times (at least a dozen) in the
past decade... and in that time (using it on many systems all along)
i have not lost any data or a single system due to disk failure...
(it's always been super easy to replace the drive and return
the RAID to fully operational status)
in fact, in many ways i prefer it to hardware RAID... as the software
RAID monitoring facility is always quick and accurate in alerting you
to any problems...
in general, i will often chose software RAID on server system disks
over many onboard RAID alternatives...
and while usually we invest in a hardware RAID array for data...
i have to mention... efficient monitoring and status reporting on the
large hardware arrays is ALWAYS more of a pain than the default handling
i enjoy on the software RAIDed system disks...
