I too have experienced the same problem of a 'fake HD' on the Amiga side being
EXTREMELY slow for the Bridgecard. Nortons may say a relative index of .9 in
your the previously mentioned letter but this just isn't accurate. I have tried
a number of hard drive speed indicators, each giving varying results.
CORETEST indicates an average seek time of 0.4 ms (yes!) but a transfer rate of
73.6 KB/sec. Not too good when you consider an 'average' hard drive and XT can
do transfer rates of 150K+. Since I installed my SOTA286i accelerator Nortons
gives an drive index of 3.6, but the transfer rate still hasn't changed. Seeks
seem to be ultra-fast because it is a software program saying to the BIOS 'yup,
you're there now' but the transfer rate stinks. To increase the rate I have
experimented with many different fake 'interleaves', sectors/track, etc (with
the MAKEAB program) but no change. I have tried increasing buffers in
CONFIG.SYS, and also trying a disk caching program on the PC and no change
again. It appears the Janus software is the bottleneck. Increasing PCDISKs
priority makes no difference as well.
