interesting sata2/3 benchmarks

Hi All,

In the processes of troubleshooting some other problem, I
make some interesting hard drive bench marks with both HD-Parm
and HD-Tune.

SATA 2 controller and SATA 2 hard drive: 202 MB/Sec (read)

SATA 3 controller and SATA 3 hard drive: 204 MB/sec (read)

The SATA 3 controller was an add on PCIe adapter. I removed
the adapter and went with the internal SATA 2 controller:
199 MB/sec

Interesting. I am thinking that the drives can only deliver
data so fast regardless on the interface. What think you?

I think you right. Same RPM etc.?

You will compare the interfaces more if you do your tests with files
well below the size of the cache memory on the drives. (Repeat the tests
several times so that they're in the caches.)
