Hello, I've setup a bunch of software RAID boxes and I've had my main one running at a friend's place with about 16 disks and 9TB of data. One time 2 disks had bad sectors and things took a bad turn. It was a RAID5 array, so I had to salvage everything I could rather than losing everything we had there (no backups). It took me about 3 weeks of working daily for about 6 hours a day in cloning disks, recovering files and validating checksums. It was not fun at all. If you have critical data, I'd suggest you add a battery and an sd-card/flash card to your hardware RAID array. At least if the power goes off, whatever is in the cache will be written to the card and later on to the disks when power is restored. A UPS will not help you if your power supply decides to commit seppuku. If you keep daily backups, or any form of backups, go ahead with software RAID and keep yourself free from vendor lock.
