Hard drive 7200rpm in laptops
I have just bought a very nice bargain from ebay. But i want the POWER. A (7200rpm hard drive). I know laptop never have been gr8 compared to desktops in performance. One of the best up grades i ever did was put a 10000rpm raptor hdrive in my destop. Top bannana. Right my question is. Can any newish laptop with ata 100 run a 7200 2.5 in hard drive. Old ones run 4200 and most upmarket run the 5400rpm.

Most I see now run 5400. Many can be upgraded to 7200, yes, no problem.
However, you probably won't notice much of a difference unless you're doing a lot of large file streaming.
The speed isn't the only consideration. Something else to think about is the bit density on the platters. You can get 5400rpm drives that have a larger capacity than 7200 drives, and so offer a great bit density and thus perform better.

ATA/100 is an interface which supports a data transfer rate of 100 Mbytes/sec.
Here is a list of maximum data transfer rates for harddrives of various rotational speeds
4200rpm... ~ 40 Mbytes/sec
5400rpm... ~ 50 Mbytes/sec
7200rpm... ~ 66 Mbytes/sec
10000rpm... ~ 90 Mbytes/sec
From this you can see that the ATA/100 interface could comfortably manage a 10,000rpm drive.
The problem with increased speed is an associated increase in heat, which is probably a greater issue in regard of laptops than desktops and could be a significant reason in limiting the speed of laptop hardrives.
