Maybe...

Are there any disadvantages of using a block driver instead?
E.g. the internal disk interface is SATA, which supports hotplug (in theory, I
don't know whether the actual SATA hardware and the HV support hotplugging the
disk).

The PS3 storage driver is used for HD, CD/DVD/BD, and 4 MiB of internal flash.

Memory Stick, CompactFlash and SD/MMC media are on the USB bus.
