Adding an external (usb) hard disk ONLY is useful
a) to store large files if there's no more room in your PC to accomodate a second internal hard disk
b) to use as backup medium
c) to transfer large files (so large you can't burn them to DVD) to other computers
d) to routinely transfer a lot of files to other computers (it's faster than burning to DVD)
It won't have any influence on the speed of your computer. That's influenced by other factors like:
- speed of CPU
- amount of RAM (in relation to what you do)
- services and background programs running
- virusses and spyware running in the background
- virtual memory settings
- defrag state of hard disk
- for certain things: amount of space in temp-folder and IE cache
Tell more about these things if you want advice (from others) about tuning up your PC.
Hi I was thinking of buying a Classic 250GB Hard Drive which you plug into your usb port to give you extra memory. I already have a 30gb hard drive and use about 6gbs of it but I have seen other compuers work much faster than mine so increasing it to 280gb's I think would make my pc load up quicker and work faster, am I right or not as I do not want to waist money for this usb extra hard drive I have seen. I use windows xp home edition just encase you need to know, if anyone can answer my question I would be very happy of your advice thanks.
