No, it won't.
1.) The limiting factor will be your internet connection. If you've got an internet connection that is faster than the write speeds of even the cheapest SATA SSD, I want to move where ever you live.
2.) I already said, even doing several GB software installs, and several GB file transfers, doesn't show the slow down that you are claiming. Don't believe me? Ok, just go look at the latest SSD review here:

Just look at the Office install graph. That's a couple GB install, and remember the test is repeated 12 times, so that multiple GB of writes to the drive over and over again. In all the modern drives, the difference is practically nothing. In fact, if you look at the OCZ Trion, which no one will deny is a "cheap" drive, and the MX300 which performed the best in the office install test, the difference is 3 seconds. That's not even a 5% difference in performance after easily 24GB written to the drive. And you'll see that trend repeat with pretty much every software installation test in the review. Even in the file copy test, which writes over 50GB to the drive, you only just barely start to see some of the drives "struggle" if you can even call it that. The cheap drives still hang in there pretty well with the more expensive drives. The difference between the best and worst SATA drive is like 5 seconds. Not what I would call a noticeable difference. If it was 20s, sure I'd say that would be noticeable, but not 5s. In fact, the drive that really starts to show that it is struggling is the Samsung 840, and it makes sense because it is old tech and it is was first generation TLC. Those drives did have the issues you talk about, but that was 4 years ago, and even the cheap controllers have improved to the point that those issues are pretty much gone.
