Finally installed the 7K100 (100GB) into my trusty S270P.  I noticed a slight increase in performance over the old 7K60, but then maybe it’s cause of all this extra free space.  :wink:  Noise levels and battery drain are on par with the 7K60.

Here are some HDTach scores for those interested:

Wow, that’s pretty good. Where did you buy the Travelstar 7K100? I’m trying to get my hands on a Seagate Momentus 7200.1 100GB model.

My current 5400RPM 100GB Seagate Momentus gets:

Max: 40.3 MB/s
Min: 19.7 MB/s
Avg: 31.7 MB/s
Burst: 83.0 MB/s
Random Access: 16.5ms
CPU utilization: 5.9%

Specs almost the same except for 1.7GHz Dothan.

So, obviously slower since it’s a 5400RPM drive. You average of more than 10MB/s faster performance is definitely intriguing. I’m wondering what the difference in power consumption is as this Momentus drive does seem to be about as efficient as a 4200RPM drive. Seagate’s claim is that their 7200RPM model uses power like a 5400RPM drive which wouldn’t be too shabby.

Hey groovy, I purchased the 7K100 from Zipzoomfly .  Thanks for posting your Momentus 5400.2 results - although expected, it’s still intriguing to see the effect RPM has on transfer rates.  Even more amazing is how these new 2.5” drives manage to squeeze desktop level performance into small, power-efficient form factor.  Let’s just say it wasn’t difficult to part with the 7K60.
