Raid 5 is not that fast, especially on non enterprise drives which often use 15k scsi. When things go wrong, you may lose the whole lot. Every year at work at least one raid 5 array due to data rot and uncorrectable sectors,and out backups come into play. Raid 5 is not a backup.

Look into freenas and zfs for reliability and you can also mount an SSD to cache too (i believe). Think the next in line is Unraid from lime technology. The third best us a dedicated RAID Card with raid-hole battery backup. There are better, but you are looking at commercial stuff like netapp, emc, ect.

Oh no, the data I keep there is not of great importance, I use RAID5 for the fact that if a disk fails I can change it hot, and the information I do not lose (although I have backup). In terms of performance, I think it can work as a RAID 0 (it's the one I like best  ;D).

Thanks for the advice!
