sn0wl Posted March 21, 2006 Report Share Posted March 21, 2006 If you demand to be mobile and still have the hard drive space you need, then you should look at the Seagate Momentus 5400.3. It's the first mobile drive to be equipped with a full 160GB of disk space, and still retains great speed. Model Numbers 40GB: ST940815A (Ultra ATA/100) 60GB: ST960815A (Ultra ATA/100) 80GB: ST980815A (Ultra ATA/100) 100GB: ST9100828A (Ultra ATA/100) 120GB: ST9120822A (Ultra ATA/100) 160GB: ST9160821A (Ultra ATA/100) Read more.

Almighty1 Posted March 27, 2006 Report Share Posted March 27, 2006 None of these are 7200RPM so while capacity is greater than Hitachi, performance is slower. Quote Link to comment Share on other sites More sharing options...
mobilenvidia Posted March 27, 2006 Report Share Posted March 27, 2006 Not necesarily, the 160GB drive has a higher bit density meaning more data is taken off the platter per rotation than the 100GB drive. So performance will probably be quite similar :) Quote Link to comment Share on other sites More sharing options...
®®® Posted March 27, 2006 Report Share Posted March 27, 2006 I had the same opinion as Almighty1 , but when i took a peek at the HDTach benchmarks posted at techgage.com, i was quite surprised. Quote Link to comment Share on other sites More sharing options...

You doubt my abilities :) More data per track means more data per rotation. Quote Link to comment Share on other sites More sharing options...
Almighty1 Posted March 27, 2006 Report Share Posted March 27, 2006 You doubt my abilities :) More data per track means more data per rotation. Hmm, but doesn't the higher capacity drives have more platters as well? I mean even for desktop drives, the slower RPM ones are always slower even if the density was higher.

mobilenvidia Posted March 28, 2006 Report Share Posted March 28, 2006 The 160GB drive uses 2 platters with 4 heads (sides) same as the 100GB and 60GB 7200RPM drives. If it's in a 9mm high case then it can have a max of 2 platters, 12mm drives can have 3 platters So as long as the extra data is added per track and not adding more tracks this will mean a faster speed per rotation. I remember my 4GB 10KRPM Cheetah SCSI hard drive with I think 15M/sec continuous speed. This is now slow for 4200RPM drives, as the data per track has increased untold.

Almighty1 Posted March 29, 2006 Report Share Posted March 29, 2006 Interesting. I think it really depends since I think Fujitsu's 4200rpm drives are supposed to be pretty fast too. Quote Link to comment Share on other sites More sharing options...
