Some experts say ; HW RAID is better in general reliability than SW RAID after a reboot sometime SW RAID machines had problem in spite of that RAID 1 mirror is most reliable in category as its Performance is best during failure. Some notes about performance:
Striping generally has the best performance, but it offers no data
protection. For write-intensive applications, RAID 1 performs better
than RAID 5.
l RAID-1 and RAID-5 volumes both increase data availability.
Mirroring improves random read performance.
l RAID-5 volumes have a lower hardware cost than RAID-1 volumes,
while RAID-0 volumes have no additional hardware cost.
