I'm thinking about upgrading my A3000 with a harddisk. Problem is,
harddisks come in many flavours. To make a good choice, I need answers
to a couple of questions:

1) Speed. As far as I know, there are 3 type of interface: ST506, 8-bit
SCSI and 16-bit SCSI. What is their relative performance? I heard 8-bit
SCSI is slower than ST506, and 16-bit SCSI is fastest, but that may
also depend on brand, disk access time or other factors. Are there any
benchmarks?

2) Compatibility. ST506 disks can be accessed by ADFS, SCSI disks need
a SCSIFS filing system. Are these fully compatible, or is there a
chance that some applications won't work?

3) I read about an *internal* harddisk for the A3000, using a 2.5" disk
designed for laptops. Has anyone seen it yet? It oughta have a really
low power consumption, as the A3000's supply isn't too big.

Any info appreciated.
