Sun had FO interfaces for their arrays in the 90's. They were fucking fast (and not limited by SCSI distances), but SSD is frighteningly fast. My 5.4" mini is SSD and I love it. Cost may be the biggest obstacle now, but that's going to change. Hard drives will be going the way of the 5 1/4" floppy. Hell, thumb drives have seriously dropped in price and I use those for backups all the time. They're sort of the new floppy, but they hold a lot more.

On Edit: Ironically, the more physical drives involved in a RAID5 volume, the less storage space you lose, but performance takes a hit. Rebuilding isn't so bad unless you use the parity drive. Either way, the more physical disks in the volume, the harder the performance hit. I like a five disk array over five controllers with the configuration partition and hot swap on a sixth controller. I've dealt with a lot of drive failures and never lost data. But yes, two down and you're fucked.

One of the biggest mistakes people make is to put multiple physical drives on the same controller and the same volume. If the controller goes, you're SERIOUSLY fucked.
