Yeah, you won't get much more than 30MB/S out of any 1394a drive on
Linux, and even then you may have to set gap count by hand to get
there. However, faster 1394 performance is available in Linux. Here's
my 1394b drive:

lightning ~ # hdparm -tT /dev/sdb

/dev/sdb:
 Timing cached reads:   2252 MB in  2.00 seconds = 1125.44 MB/sec
 Timing buffered disk reads:  172 MB in  3.03 seconds =  56.72 MB/sec
lightning ~ #
