Ok, I'm certainly seeing improvement. The amount of "ehci" interrupts is down
to hundreds (although still very high, considering, there is not USB
activity).
The disk's write throughput increased a little from 7.5Mb/s, and even spikes
to 10Mb/s occasionally now, while averaging at about 8.3Mb/s. Curiously, the
bandwidth appears BETTER (9Mb/s), when boinc (setiathome) IS RUNNING on all
four cores...
I'm running a compressed dump now to see, if the data corruption is still
here.
That said, it still sucks... The drive can read at the healthy 60Mb/s (and
higher) -- I'd expect writing to average at least 20Mb/s, when recording a
single stream.
BTW, when I just got the drive 15 months ago, reading sucked too. But it
improved over the period -- not sure, with which revision...
Thanks!
