ZuluSCSI and others are quick but they cannot necessarily be faster than some other drives. The biggest benefit is reduced heat output, which if you have read at all, can kill Indy systems.

To install and handle software we usually recommend using network installs (e.g. using LOVE or Reanimator) and for transferring files, ftp and/or NFSv3 (though, IME, this only works well for Solaris, BSD targets. MacOS and GNU/Linux require a ton of fiddling and windows doesn't support it)
