Note: "permalinks" may not be as permanent as we would like,
direct links of old sources may well be a few messages off.

I've run each test 10 times consecutively.
The 10 results are equivalent for each test.

The partitions used for the tests are empty.

I don't understand very well your question about cache.
I use IDE disks with write cache enabled (with hdparm).

Here is the command line of bonnie++ : bonnie++ -b -s 3g
I use "-b" option for "fsync() after every write".

If you need more informations, do not hesitate.
