This is why people (Gamers usually), use harddrives that have a spindle speed of 10,000, or 15,000RPM.
Also why people use SSD harddrives. (Solid State Drive)
(Problem is those harddrives have a small storage capacity, in relation to harddrives that spin at a slower spindle speed.
One example; 1TB harddrive that has a spindle speed of 7,200RPM, compared to 10,000RPM harddrive with only 150GB )
To really improve the performance past that Bob, make sure you have the Ram Memory maxed out.
If the laptop for example, has 1GB of ram memory, and will support up to 4GB; this is the way to go.
Also, let's say the laptop uses DDR2 Sdram at 667MHz.
(PC2-5300 that is SO-DIMM)
But can support DDR2 Sdram at 800MegaHertz.
(PC2-6400 that is SO-DIMM)
It is BETTER to have MORE ram memory, than it is to have faster ram memory.
The first memory area for the Processor is the Cache.
(L1, and L2. Newer processors? L3)
This is a small memory area for the Processor.
Operates at same frequency rate ('Speed') as the Processor does.
Therefore it is the first memory area the Processor accesses.
Next in line is the Ram Memory.
Ram Memory typically operates at HALF, of the Processor's FSB.
(Front Side Bus)
Do not have enough ram memory? Then a small memory area is created on the harddrive. VIRTUAL memory.
Virtual memory is typically 1-1/2 times the ram memory.
More ram memory, faster computer.
Next memory area is the harddrive.
IDE (PATA) and SATA harddrives are mechanical.
As such they are way slow, in comparison to the frequency rate ('Speed'), that ram memory operates at, much less the Processor's cache.
SSD harddrive? Still doesn't operate as fast.
Want to speed your computer up even more?
Delete anything off of your harddrive, that you are not using.
(NOTHING Windows, though)
Programs, and applications.
Copy off personal documents.
Personal documents being photos, videos, music, and personal documents you have created, or downloaded.
The more stuff on a harddrive, the slower the computer.
Hit 50 percent full? You start to notice.
Hit 70 percent full? You REALLY start noticing now.
Also use a registry cleaner. (I use CCleaner. It's FREE, and works as well as paid for versions, plus better than some)
Cookies, and fragmented files take up room also.
Delete a program, photo, video, music, whatever; and bits of fragmented files are left over.
The more room on a harddrive, the faster the computer.
Remember back when the computer was new?
