We have an SS2 in the server config (internal 207MB disk and an external
669MB (which doesn't have the same config as my Wren 6's, but well be for
all I know, as Sun's disks are called SUN0207 & SUN0669 rather than Wren-X),
a 150MB tape and CD-ROM.  The Sun chappie who installed it said that the
internal 207MB disks are rather slow.  This may explain your results.

The /var/adm/message contains the lines...
|Feb 18 11:26:30 beefcake vmunix: esp0:        Target 3 now Synchronous at 4.0 mb/s max transmit rate
|Feb 18 11:26:30 beefcake vmunix: esp0:        Target 0 now Synchronous at 3.334 mb/s max transmit rate

So, they both appear (at least) capable of doing Sync SCSI.
