Yes. ATA and SATA raid (Which is the majority of low budget linux software raid stuff)
I realise scsi is hotswap. It comes with the turf.
I would find it pretty hard to justify the expense of scsi for my 7 drive 1.4TB low speed array (Low
speed because I never *need* more than about 2MB/s in any direction but I need heaps of space)
