I'm using a pair of SFD-1001 drives ($238 each) with Skyles (sp?)
IEEE Flash C-64 interface ($99) with my C-64. They hold over a megabyte
each and are in the range of 3 - 7 times faster than a 1541. (The 1541s
are sooooo slow compared to the SFD-1001s).

I mainly use my C-64 with PROMAL which runs fine on SFD-1001 drives
with a 1 byte patch.

Advantages of SDF-1001 drives:

	1) Fast
	2) Huge storage
	3) More buffers, can have about twice as many files
	open at once (this was a big problem for me).
	
Disadvantages:

	1) Need good disks (DSQD)
	2) Back up of entire disk takes an hour (over 4000 blocks),
	anybody got a 3-minute copy program for a SFD-1001 drive?
	3) Will NOT work with COMAL 2.0 and most copy protected
	software.
	4) Directory is limited to about 225 entries. As most of my
	files are small (15 blocks avg.) this is the limiting factor
	as to how much I can store per disk.
