just to throw a spanner in the works, if your 1tb external drive dies, thats a lot of pics to lose. maybe worthwhile buying two 500gb drives and either spread pics across them, or duplicate pics across them.
On the speed issue, you dont mention what OS/version of windows you're using, but the usual first steps are to run;
1. disk clean up.
2. disk defragmenter.
3. a malware check (use malware bytes and then spybot search and destroy, then ccleaner).
The unpalatable bit is if you've been running the machine for a few years, one of the best ways to speed it up is to rebuild it. no one likes doing this, so if you do start heading that way, find a local friend who can help out (best to diagnose the machine first, check page file usage etc).
Good luck
ps. for external drives people all have their pet favourite brands, wd, seagate, iomega, freecom all rate well.
