Bought a SSD. Immediate advantage :-

1. Damned fast. Its like the first time you use a hard disk after being stuck with 5.4" floppy for your work. Thats the feeling you get when you move from HDD to SSD.

2. No sound. Not "Whisper Quiet", or "Silent Running", Or "Accoustic Dampened", the drive simply makes no sound. No whining as it spins up or down.

3. Very Cool - I use it in a MacBook Pro. By now, I should be feeling heat, but I'm not.

4. No worries about chipped plates as you move your notebook around.

Note to Mac OS X users - Your primary choice should be Sandforce based controllers, either the SF1200 (OCZ Vertex 2, Corsair Force Series - Do note that some reports that this series have got firmware issues). For Vertex 2, get a firmware update (latest is 1.11) to get the best performance.

Reason why - Mac OS X don't support TRIM, so write speeds are going to suffer, therefore need one with good garbage collection, or better yet what you could abuse (write so many small files) without degrading performance too much.

Avoid Crucial's RealSSD. Not sure how well Kingston V+ handles small writes, and how it would degrade over time.
