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 ~ # - Mark -- gentoo-amd64@g.o mailing list
