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? ...
