    Another vote of confidence for the DataFrame. It's been getting good 
    reviews in the press and on the net. I'm getting that much closer to 
    actually buying one :-)

    Actually it's the DataFrame XP. I talked to the SuperMac people at 
    the MacWorld Expo in Boston. They had 20 and 40Mb XPs at the show. 
    I spent some time playing with a Mac that had a DataFrame 20 and a 
    20 XP hooked up to it.  Unfortunately, I didn't have enough time 
    to get a good idea of the speed difference.

    One thing I thought was a good sign was that a lot of the exhibitors 
    at the show were using DataFrames. Of course I also heard that SuperMac 
    was selling DataFrames for cut-rate prices to exhibitors. On the
    other hand, would you show your pride and joy on a drive you didn't 
    trust?

    Their literature claims that they get the speed up by doubling the
    transfer rate of the SCSI port (600 Kb/sec vs. 330 Kb/sec). They 
    said at the show that this involved adding their own ROM to the
    Mac (on a board that plugs into the current ROM socket, I believe). 
    So I guess the increased transfer rate is just better software?
