T60 - Hard Drive performance
Posted: Tue Feb 17, 2009 7:57 am
I replaced my hard drive with a 7200 Seagate drive (ST9160823AS),
I noticed my drive was not performing well, and found some tips that I have applied, but I
am unsure if all is what it is supposed to be.
Here is what I did, I removed the drive and removed the jumper, according to some
post this puts the drive in SATA II mode, yet the T60 does not support SATA II,
but then again I managed to boot and the drive seems to work.
Should I leave the jumper off ? or does this mean my T60 does not supports SATA II
(8744HDG)
Then In my BIOS I set the DRIVE to Compatibility mode ,
since this will turn off NCQ (Native command queueing), this seemed to make my OS
more responsive, whenever there was disk activity on the T60 (AHCI MODE), I could do nothing but I had to wait for the disk activity to complete (serialized).
(Some post mentioned that IBM removes the NCQ on the IBM drives, and a method to remove NCQ
on NON IBM drives are to set the BIOS to compatibility mode).
I am not convinced yet that my DRIVE is optimal as is should be, I did some tests with
HD Tune, and the results were pretty much the same:
AHCI on:
Min: 27.9 MB/s
Max: 56.9 MB/s
Avg: 44.8 MB/s
Access Time: 14.6 ms
Burst Rate: 53.2 MB/s
CPU Usage: 14.5%
Compatible Mode
Min: 29.7 MB/s
Max: 57.0 MB/s
Avg: 45.2 MB/s
Access Time: 14.7 ms
Burst Rate: 89.1 MB/s
CPU Usage: 3.3%
I am also wondering what Client Security Solution has an impact on the DISK performance,
I am not sure how the Client Security Solution Disk encryption works.
Please post some Thoughts comments.
thank you.
