Arrrgh! (FastATA 4000 MK-VI 8.0 and issues with keyboard.)

Now I didn't say it would make sense, I just thought you might squeak out another byte per second over sadly slow interface.  I don't know why UWSCSI was limited to just the Cyberstorm MK 3 & CSPPC.  35 MB/s is nothing to laugh off in the Classic Amiga field, and has to be bit easier to design than an accelerator.

I have a fast 68 pin SCSI drive with my CSMK3 and the best I have seen in multiple benchmarks is a little over 30MB/s which it can sustain. You may be right about peak or theoretical transfer speeds though. These boards also have one of the lowest CPU usage for the SCSI speed of Amiga accelerators. It's almost overkill for the Amiga but it sure is nice for compiling and image editing of 32 bit images.

I believe that if it seems fast, then it is fast.  I test stuff and report it just so it can be found on the Web, (not to make my phallus size seem larger).  However, a U320 15K rotation speed HDD will get 36 MB/s out of a CSPPC/CS MK 3.  Those numbers don't mean much in real world applications.  I wanted the FastATA 4000 to backup partitions to a CF card faster than the standard A4000T IDE.

Hear are my SysSpeed MB/s results with a 10k Atlas V:

CreateFile 28.71
WriteFile 32.77
ReadFile 29.72
RawRead 27.64

I had an older 15k Atlas (III?) before that was a little quicker but not much (1MB/s?). I choose to look at the average which is about 30MB/s. Maybe you were using another benchmark program or looking at the best result?
