SCSI Compact Flash adapter? Or Acard?
« on: January 13, 2008, 12:12:34 PM »
I'm currently backing up my A4000's SCSI hard disk to a FAT formatted Compact Flash card in an IDE adapter on the internal IDE interface. It is *slow*. Is there any such thing as a Compact Flash to SCSI adapter which I could connect to my MKIII? Alternatively, will a Compact Flash to IDE adapter connected to the MKIII through an Acard IDE->SCSI bridge run significantly faster than the IDE device connected to the A4000's internal IDE interface?

Maybe so, but I'm not using an A1200 :-P

I'm painfully aware that the A4000's internal IDE interface is very slow. I just don't know whether an IDE device will run faster when connected to the SCSI bus, or whether latency introduced by the Acard will negate the benefit. If a native SCSI CF device exists, I'm sure it would outperform the Acard.

@meega
Oops! Edited ;-)

@Piru
I don't know whether there is latency or not. My question was, will the Acard with an IDE device connected to the MKIII perform significantly faster than the same IDE device on the A4000 IDE interface. And if a native SCSI adapter exists (CF to SCSI) would that be faster still?

Thanks - that answers part of the question, and fortunately the one which saves me looking for a possibly non-existent piece of hardware :-)

Just want some confirmation that the Acard is significantly faster than the internal IDE adapter before I shell out for one.

Thanks for the suggestion, but I think USB would be even slower on an Amiga. Also, I have been advised that USB mass storage is not reliable on an Amiga, and since this is for a backup, I would prefer to stick with reliable solutions.

Umm, that's what I am doing now. It's slow, which is why I want something on the SCSI bus.
