Dear Peter,

Finances permitting, I would always suggest an SSD for lots of audio I/O, but
if that's not possible maybe a second hard drive, and use whichever is the
faster of the two for writes and the other for reads (writes to magnetic media
take longer than reads).

Say you have a poem and I have a tune.
Exchange them and we can both have a poem, a tune, and a song.
this looks indeed pretty slow, is it an external
usb-2 drive?
No, it's an internal S-Ata drive, apparently a SAMSUNG HD154UI.
You may perform a simple check:
sudo hdparm -tT /dev/sda
For cached reads this averages around 1200 MB/Sec, for
buffered reads
around 108 MB/Sec. I didn't find an option to test the writing speed. As
a write test, I tried this:
dd if=/dev/zero of=out.file bs=1M count=100
with a result of around 560MB/Sec
If your are just recording, can you increase the
buffer length in jack?
I could, but I already have it a period size of 256. At 512
I started to
get a noticeable delay. With cards that can potentially go down to 64
samples, I feel a - perhaps unreasonable - hesitation to set the period
higher. Is this very unreasonable?

Best wishes,
