With 1:3 hard interleave on my ST277N,
 in an empty 40Meg FFS partition,
  with 30 buffers,
   using the StarDrive's FASTMODE,
    my best 68010 diskperfa times were:

File create/delete:     create 16 files/sec, delete 50 files/sec
Directory scan:         106 entries/sec
Seek/read test:         108 seek/reads per second
r/w speed:              buf 512 bytes, rd 84562 byte/sec, wr 27887 byte/sec
r/w speed:              buf 4096 bytes, rd 137970 byte/sec, wr 124830 byte/sec
r/w speed:              buf 8192 bytes, rd 187245 byte/sec, wr 154202 byte/sec
r/w speed:              buf 32768 bytes, rd 291271 byte/sec, wr 187245 byte/sec

That partition is now about 33% full, I suspect fairly fragmented, and the
times are now:

File create/delete:     create 14 files/sec, delete 37 files/sec
Directory scan:         96 entries/sec
Seek/read test:         95 seek/reads per second
r/w speed:              buf 512 bytes, rd 84562 byte/sec, wr 27025 byte/sec
r/w speed:              buf 4096 bytes, rd 131072 byte/sec, wr 104857 byte/sec
r/w speed:              buf 8192 bytes, rd 187245 byte/sec, wr 131072 byte/sec
r/w speed:              buf 32768 bytes, rd 238312 byte/sec, wr 145635 byte/sec
