I put my first one in last night. A Crucial M4 64gb.
Boots maybe a 20-40 seconds faster. It's a significant difference.
Knocked my system imaging time to a spinner from 4 to 3 minutes.
Obviously faster reads are seen in both those cases.
I forgot to note the time on a system image restore.
Changed my WEI disk score from 5.9 to 7.8. Whoopie.
Not using Access or Oracle or Photoshop or any really data-heavy apps.
So for what I usually do, which is browse the net, watch Youtube, read/send e-mail, and play games, the difference hasn't added up to much more than a hill of beans.
When I install a game on the drive, I'm sure it will load faster; that will be a plus when playing something that requires me to reload a lot because I'm getting my butt kicked. But I might not notice - because I'll be mad about getting my butt kicked.
My hardware was fast enough already that I had no complaints.
That's all personal perception, of course.
I don't regret buying it - it cost me about 30 bucks on Amazon after getting the $50 gift for signing up for their CC, and that will cost me some time to pay the first bill and then cut up the card.
Anyway, just some observations. SSD's are the future, but if your computing habits are similar to mine, and you have decent spinners, think a bit before spending too much on them. They are far from "necessary."
Nice, but not necessary. If you do decide to buy, enjoy! I kinda, sorta do.
