I'll run with this.



Kinda slow, actually. Anyone got any tips for a Compact Flash drive in a 2000 on a 2091 controller? Could bad termination be slowing things down? We're talking transfer rates in the 90K/s range.


You using an accelerator?  2091 only has SCSI, right?  What's your converter?

Yup, got a A2630 with heaps of RAM. 2091 is SCSI only (also with full complement of RAM), and driving a native SCSI card reader.

90k/s sounds a little slow to me.  I haven't done any SCSI->IDE(CF) work, so I can't speak on the performance of the converters.  I do know from experience that different cards perform better, even within the same speed class.  Have you used something like SCSI Bench to test raw throughput and CPU load?

Hi,

Been trying for about 18 months now to get a CF and a CD drive working together, I don't think it can be done, something there is not allowing something not to talk. Anyhow if I use the CF drive alone it works great. And Paleese don't say I need a buffer for this to work, I have a 4 way buffered ide interface.

This is what makes the Amiga fun

That and the Voo-Doo of SCSI.  If you're trying the CF and CD on the same chain, a thought comes to mind: master/slave configuration, but not your settings -- maybe the CF or its adapter doesn't like having a slave present.  I've seen that in the world of old IDE hard drives.  If they're on separate chains, then your guess is as good as mine.  Anyone have an IDE protocol analyzer?
