[comp.sys.amiga.hardware] A590 Speed

emwessel@praxis.cs.ruu.nl (Eric van Wessel) (10/03/90)

Hello folks,

I recently bought an A590 hard disk and installed it.
The "problem" is that the transfer rate is only about 
100 kb/s (according to diskperfa)
Does anybody know how to improve this speed ?

B.t.w. : Configuration A500, KS1.2, WB1.3, ARP1.3, 1 Mb



Thanks, Eric

Hi,

I have a A590 harddisk for almost a year now. I am quit happy with it,
when I compare it with floppies. It is only a little slow (150 Kb/s). 
It is still using the original drive (a 20MB WD 65ms). But that alone 
is not the reason for this low speed. A friend of mine has rewritten 
the software for his OMTI-controlled harddisk and doubled (!) the 
read-speed from 160 Kb/s to 340 Kb/s. I wonder if someone has also
rewritten his A590 software or is the slow speed due to the controller-
hardware. The SCSI-controller is capable of 600 Kb/s. How is the XT-
controller connected to the Amiga: i.e. what makes it so slow compared
to other cheap harddisks?

thanks in advance,

Erwin van Breemen

The reason the A590 is slow is the hard drive supplied with it is very
slow. If you hook any fast drive to it (say a Quantum or a Wren), you'll
get speeds in the 800-900KB/sec range. I've seen a Wren III hit around
850-950KB/sec when attached to an A590, about the same speed as the
Hardframe controller for the A2000.
