SCSI may be better, but the cost is MUCH higher than SATA.

For example, a hot-swappable 73GB SCSI drive costs twice as much as a
200GB S-ATA drive.

For ~180 EUR you can get a Promise FastTrak S150 SX4, a hardware
RAID-0,1,5 controller with hot-swap capability.

Intel offers a SATA hot-swap drive bay for (at least) one of their chassis.
