If i ever need to get a new Hdd, i know that i want to buy 7200 RPM for the faster read/write speed.

How do i check what speed my current Hdd is right now?

HD Tune is neat.

Or in the absence of any utilities, note the model of drive shown in the POST report, or in Device Manager, and Google the specifications.

Just was thinking, does a higher rpm affect vitural memory at all? I have plenty of RAM, 2GB , right now i am using 863MB. So i dont think my VM is ever used. I just looking into a faster read/write speed if i need to ever replace my hdd.

If Windows does use the page file, a higher performance hard drive will reduce the lag to some degree. If you have adequate RAM, page file usage should be minimal, but can still happen at times, especially if you have several applications multitasking.

Since 3.5" HDDs are normally 7200RPM now, I guess we're speaking of a laptop drive?

yes my laptop is 5400 rpm. Its working fine. I did a google search of the model. When i need to replace it, i am going to get a 7200rpm.
What are the normal speed that are available today? i know that 5400 and 7200 are some, as i am sure there are faster( as well as slower) speeds.

4200, 5400 & 7200 that I'm aware of. Performance laptop drives are moving toward SSDs (Solid State Drives), but ones that actually are fast and should give long life are still expensive.

You won't necessarily see a large jump in performance going from 5400 to 7200 RPM. I bumped the 4200 RPM drive in my smaller Compaq laptop up to a 7200, which is a noticeable boost, but it runs significantly warmer. I wouldn't like to use it for long in a non-airconditioned environment. Also you hear it a little more than the 4200.

I also fitted a 7200 RPM drive in the second drive bay in my newer HP, it is just a little faster than the 5400 (which is larger capacity, this often boosts data transfer rate anyway).

As soon as SS Hdd comes down in price (and to a high enough capacity) i am going to buy one. Pretty soon there wiill be NO moving parts in a computer, other than a the CPU fan right? Current tech Hdds are starting to show thier age, and i am sure that Disk drives (CD and DVD ) are going to the same fate as the Telegraph. LOL

Given time, I think that's true. It's surprising how traditional technologies can fight back though.
