I've got two of the Maxtor 5000XT (250G, 5400rpm, USB2.0/Firewire interface).
They work great using the ieee1394 interface and the sbp2 module. I'm running
Plug in, install the sbp2 module, and suddenly as SCSI drive appears.
I have tortured the drive and SCSI emulation is solid. Also since
it is a SCSI device there is no fussing with master/slave,
size limitations, and DMA problems like IDE drives. This is as it should be:
a reliable drive without the IDE headaches.
- sustained transfer rate, eg., measured by "bonnie" benchmark,
20MBytes/sec (at middle of drive)
This is about 50% the ideal firewire capacity, probably 75% of
of the drive's raw capacity if I had to guess.
- I have not tried more than one drive on the same firewire
connection (ie., daisy chain).
As far as "one touch" goes, I don't use it. I haven't tried to hit that
button. Maybe it sends something to the firewire. I don't know. To do
backups I use "rsync". This program is like rcp, but only updates files that
changed. I mirror my entire desktop machine every two weeks or so. It has
some 400,000 files. It only takes a few minutes each time.
Another concern I had was media reliability, so every so often I read the
entire filesystem media to make sure it is OK. If the drive is mounted on
/mnt/hd, I use the command:
cd /mnt/hd; tar c . > /dev/null
cd /mnt/hd; tar c . |md5sum
This does nothing more than read the media. The first line just reads,
while the second line does a checksum (eg., to compare multiple copies)
Anyway, have fun with it.
BTW, These drives are great for backup, but I would not recommend these drives
for continuous use as your main drive. Why? Well, I would rather have my
main drive in my desktop case so that it is not succeptable to bumps or other
damage while running. It is my belief that drives are much more sensitive
to bumps/vibrations while running than while off (when the heads are parked).
