Does Hard Drive and Memory affect the speed of a laptop? If so, how so?

Just wondering if I should attain the extra hard drive and memory... I want a vigorous laptop.


Answer:

Don't go buying DDR2800 because the guy above told you so, trade name sure you buy whats compatible with your notebook first. A polite place to start is http://www.crucial.com/systemscanner/...



As of the hard drive, unless its close full it shouldn't slow down the notebook. If its near full you can uninstall unwanted programs and other stuff.



To find out how much free complicated drive space you have available, dance to my computer and right click drive C and click properties. There you will see a pie, the pink portion represents the available free disk space.
for speed, what to look for in a not easy drive is rpm. Usually a laptop hdd will be 5400 or 7200 rpm. Obviously, 7200rpm is faster. For memory, what you want to look for is ddr2-800. The 800 represents the effective speed in mhz of the memory. The highly developed the number, the faster it is and the faster the system can access it. However, with dignified speed memory (especially ddr2) cas latency can become an issue. This is a measure surrounded by ms of how long until the system can re-access the same dimm slot. So, if you can, look for the unbeatable speed on memory while at the same time try and find a cas latency number of no greater than 4 for ddr2. This will ensure speed.
