Just a quick shout out for the ZuluScsi mini--I "installed" one (if that's what you can call plugging it in) on my Macintosh SE, and after a quick LIDO format of a volume, initialization, it was ready to go and I dragged over everything from my HD20 disk image. I was off to the races.
Loading times for big apps dropped 30-40%, and doc loading/saving in those apps is much faster.
The only hitch, for me, was I wasn't sure how to use it until I found the Git page. A short instruction sheet would be helpful to include, to get buyers started ASAP. BMOW's FloppyEmu really nails that.
Really enjoying the ZuluSCSI, and very happy the SCSI2SD wasn't available when I ordered, or I wouldn't have likely tried it! I think Zulu is pretty perfect for my needs, as the mini is well-protected in its case, the SD card is easy to get to, and of course dead-simple to move between Mac's. Initially I wanted an internal SCSI2SD with the SE mounting bracket (sold out), but this is really great.
