I would reduce it to large file copy operation over gbit or above.

The other use-cases of laptop hdds are mostly limited by the single=20
drive latency factor.

The nice point is, as I mentioned, that the 7k320 is a sata2 drive that=20
will work without any trick or what else in sata1 thinkpads.
I personally use a 7k200 and my father a 7k320 the performance benefit=20
in booting and working with the box is unbelievable additionally you=20
should maxout the ram to get optimal results.
