In case you folks are interested, I ran DiskPerf on my beastie:

B2000 Rev 4.4
A2090a
A2620
Rodime SCSI HD.  Basically, it is their 180MB 5 1/4" SCSI drive, with a few
       hand modifications.  Like, 12msec access, 12MHz transfer.  Hee-hee.


Results:

File create/delete:    create 18 files/sec, delete 52 files/sec
Directory scan:	    156 entries/sec
Seek/read test:	    135 seek/reads per second
r/w speed:	    buf 512 bytes, rd 80556 byte/sec, wr 29289 byte/sec
r/w speed:	    buf 4096 bytes, rd 197844 byte/sec, wr 171897 byte/sec
r/w speed:	    buf 8192 bytes, rd 327680 byte/sec, wr 257846 byte/sec
r/w speed:	    buf 32768 bytes, rd 635500 byte/sec, wr 372275 byte/sec
r/w speed:	    buf 131072 bytes, rd 655360 byte/sec, wr 427990 byte/sec
r/w speed:	    buf 524288 bytes, rd 699050 byte/sec, wr 455902 byte/sec


Unfortunately, I was surprised the numbers were so low.  I had hoped for
significantly higher. Anyone have any suggestions?  Or are these fast for Amiga
drives?
