I bought a used 29160, and it worked at 160 MB/s OOTB, thanks for the
suggestion!

I've done some tests (hdparm -tT, build the Linux kernel with ccache)
and have seen that my SATA 7.2k ST3320620AS outperforms U160 10k
MAN3184M by up to 30%, so I decided not to use it for the rootfs yet.
I've read that SCSI should perform better with many concurrent requests.
Any simple test scenario I could try?

With kind regards,
