stereo, especially in duplex mode.
The HDA standard (in as much as there is such a thing) is stereo in at
16bits, though some have 20bit. The 20 bits seems to be a waste of time
as, in my experience, the s/n on even the line inputs is something like an
old cassette recorder. On my desktop it is not even uniform from one
channel to the other :P I have my internal audio disabled in bios. I also
have an old ensoniq 1370 which is much quieter than any internal audio I
have heard. The ART dualUSBpre would be a better bet (or something
similar)... it does have the USB problems but it is USB1.1 so bandwidth is
low and for recording you may get away with quite a high latency anyway.
It is very small to carry and USB powered. (remembering you also mentioned
a mixer :) )
Outputs are mostly 24bit though and normally reasonable quality
amplification.

Thank you :)
I disable onboard audio too, but I don't have the money for an USB
device yet. Analog mixers are still common here ;).
Regarding to the spin down issue I'm running
[rocketmouse@archlinux ~]$ cat /usr/local/sbin/no-spind
#!/bin/sh
# /usr/local/sbin/no-spind
count=0
echo 0 >/run/media/rocketmouse/u1.1tmp/.no-spind.counter
while lsusb -d 1058: >/dev/null; do
sleep 300; ((count++))
echo $count >/run/media/rocketmouse/u1.1tmp/.no-spind.counter
done
exit
at the moment. This is just a makeshift, since I need to manually mount
the partition and I need to start the scrip manually, each time USB was
disconnected.

Ralf

This does work as expected, I just wonder if here's the need to spin
down the drive from time to time, since it's plastic-covered, it perhaps
could become too hot. It's just a little bit warm at the moment, not
hot, IMO there is no risk of overheating.

Always wondered why people felt the need to by external drives when you
could get a better external drive housing and put the drive of your
choice in it ...

Other dealers are still around 25.00 € for a 3.5" SATA/USB 2 case, so it would be
around
75.00 € still for 1TB

The WD I bought:
http://www.reichelt.de/External-HDD-3-5-8-9cm-/WDBAAU0020HBK/3/index.html?;…
95.90 € for 2 TB (but around 1 TiB, maybe 1TB would be ok), but
this was the absolute price limit for me. In the next three
years I might do schooling to became a registered child
care worker (I'm a 46 years old audio engineer but can't
stand this business ;), so I won't have enough money in the
close future.
If spinning down all the times or using a script to prevent against
spinning down should shorten the lifetime, than indeed it would be
smarter to buy a case, since I don't know if I can open the WD case and
replace the drive. I even don't know it it's SATA inside. 14 days sale
or return, it was delivered at 2013-02-28, so I still could give it
back. I will not give it back, but test it, but I wouldn't order it
again.
The counter is at 105, so it's running > 105 * 5 minutes IOW > 8 hours
and it's just a little bit warm. Heat isn't an issue, but perhaps
continuous operation, the count of turns, I'm not sure if those drives
have the same motors as internal drives.

When I don't keep the drive activated by the script, so that it will
spin down, it will spin up after a while, just to spin down again, even
if no partition is mounted, IOW I don't access the drive, so it would be
ok, if it would keep the heads parked, but it spins down and up, again
and again.
I'll sent a request to the vendor.
