1. Your software will start very fast but the overall software process speed will not be boosted a lot.
2. If you are working with large files like big photo files or if you are working on video files with softwares like Photoshop, Final Cut, you will have a decent performance upgrade.
3. writing & reading files will be a lot faster than before.
4. Boot up will halve, if you were booting up in 30 secs, with an ssd no matther how slow it is you will bootup about 15 or 20 seconds.
5. You will save battery life up to about 5 to 10%
6. You computer will be almost silent like a cemetary except the fan noise and keyboard noise you will not hear anything.
7. You computer will not vibrate.
8. You files will not be corrupted
Though, it has some disadvantages :
1. SSD's ARE VERY EXPENSIVE
2. You will not have large capacity.
3. You might need an external hard drive to keep your database.
4. Performance sometimes drops down a bit after a long usage.
In spite of all these disadvantages and it's EXTERMELY EXPENSIVE price, they are still worth to buy.
It is the final EVOLUTION of disk drives.
Today I orderded a low end 13inch macbook pro with a 128GB SSD
I do not want bulky, noisy hard disk drives anymore.
Once you use SSD, you will never want to turn back to hdd's
