• Answer:

  An external hard disk will not speed up your computer. Try to upgrade your memory to 1GB/512GB. If you got the budget, upgrade the processor. External USB hard disk is good for you to store data in to it or use it as a backup. Always keep your existing hard disk space 1 or 2 GB free. Try un-install any unused application and clean up temp Internet folder And defrag your hard disk. It will speed up a bit in term of performance.
