A third alternative is just get a much bigger SSD. Lots of much better choices than a consumer level 7200K RPM drive.
Yes, for your application access time is far more important than sequential transfer speeds.

They use different baseline system configurations so the numbers won't line up perfectly, but they should give you a rough idea since many of the benchmarks themselves are the same.
That said, I'd wager to guess that the old drive is starting to feel like an anchor simply because of how fast the m4 is. In the Performance Retrospective article, you can already see how much faster the X-25M is; looking at the initial m4 review that happens to compare the F3, X-25M, and the m4 you actually can get a direct comparison with one of the drives you're looking at. I'm not saying don't buy a new drive, however, you should still see a slight boost in performance; just don't expect it to be a huge improvement since you've been "spoiled" by an SSD.
