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.

Big difference in speed when moving large data files on encoding. Might give it ago and see what the speed performance is like. As i said in main question. The 10,thou rpm h drive i have is just amazing. cheers
