What sort of performance increase should you expect to see if you use one of these instead of a standard mechanical HDD? Or do people buy these more for the silence aspect? Just curious, because the write speeds don't seem as fast as I would have expected!

It's the access times, 0.2ms compared to 8ms+ for Raptors and 12ms+ for 7200rpm drives. Now that SDD read/write speeds compare to HDD ones they are very attractive indeed.
 
10000 writes isn't that bad when you work it out.
Assuming wear levelling is available and using 93MB/s as the write speed on a 64GB drive.

It would take 688 seconds to fill 64GB. To fill it 10000 times over will take 6880000 seconds = 79 days.

If your PC is on for an average eight hours a day, thats 237 days.

But your PC won't be writing to the drive for the full 8 hours - with a 20% write rate (that's 535GB written to the drive), you get 1185 days or 3+ years.

3 years is probably about the time for an upgrade.

but if the same section of the disk gets multiple writes (which it will) then it'll be a lot less than that

!
 
This sounds really good, prices are really dropping on these, i suppose in 2010 they'll begin replacing laptop drives and in 2012 or so the high capacity, low price drives will be out. Gonna use one of the 32GB ones for my bootdrive next time i do an upgrade, hopefully there will be other companies in the race by Christmas.

Your forgetting that the pagefile is being overwritten on the same part of the disk the whole time the pc is on, same goes for temporary files and any other type of cache, hibernation mode etc. It will lead to damaged sectors long before 3 years.

I thought the controller within the SSD takes care of this by continuously remaps the logical sector address to a different physical address to balance writes throughout the disk (flash memory).
