The following is from the Rodime 200E series drive manual (hope this is
the same for 200 series):

Drive				RO201E	RO202E	RO203E	RO204E

Platters:			1	2	3	4
Heads:				2	4	6	8
Cylinders:			640	640	640	640
Formatted capacity (typ):	10.49	20.97	31.45	41.94
	per track:		8192	8192	8192	8192
	per sector:		256	256	256	256
	secs/track:		32	32	32	32
Transfer Rate Mbit/sec		5	5	5	5
Seek, track to track:		8	8	8	8
	avg:			55	55	55	55
	max:			130	130	130	130

DOS drive type:			-      2,25	3	40

Note that the drive types don't fit exactly - all drive types above
actually use only 615 cylinders, so you miss 25 cyls... The difference
between the alternative types above have to do with at what cylinders
write pre-compemsation starts. You'll get a little more bytes per
drive than listed above since DOS uses 512 byte sectors (you get 17
sectors / track ).

I have been using a RO203E for quite some time on my home machine, and
it worked great (better than others brands I've tried). It's bit slow,
but what the heck - I got mine free...:-) Hope this helps.
