How do I determine the read/write speed?

try diskspeed from here or sysspeed from aminet (i think)

Hey mate,

Depends on what kind of size you test on.
I use SFS and have a SCSI-IDE bridge as a solution until i get a real SCSI-drive (far better at smaller file load due to seektimes on scsi drives)...

But on big files, scsi-ide bridges is pretty ok...look below
Testing with a 262144 byte, MEMF_FAST, LONG-aligned buffer.
Create file:      6488712 bytes/sec
Write to file:    8995137 bytes/sec
Read from file:   8565100 bytes/sec

Testing with a 524288 byte, MEMF_FAST, LONG-aligned buffer.

Write to file:    9343746 bytes/sec
Read from file:   7710117 bytes/sec

You should get like 4-7MB with that PF, set buffers on testdrive? And all drives gives same result?

What is your system?
