It sucks, but it was a lesson :P Yeah it was hardware raid, didn’t have enough drives for raid 5. It sucks, but it was a lesson :P

Use Raid5 if you can afford to lose a little bit of disk space for writing the parity information. Only requires 3 drives, minimum, and it is suggested to use 3 physical drives, not logical ones. I'm also a fan of hardware-based RAID, not software-based. Software-based just made me feel a little uneasy. So, get a controller card that supports RAID in the BIOS of the card when the server boots. With Raid5, you can yank a drive hot (usually, but depends on the manufacturer's solution) and the server still runs. Note that depends -- some RAID5 implementations require that you turn the PC off before removing the drive, although I would think that would be dumb. So, I purchase hot-swappable RAID5, instead. And yes -- backups are super critical. Yikes, Raid1 blows. Use Raid5 if you can afford to lose a little bit of disk space for writing the parity information.
