agree with mutantmagnet.
This generation is probably the first generation of SSD's that are worth looking into.
For reference, I had a Super Talent 32GB MLC SSD, one of the first of it's kind under $300 of a few years back. It took about 6 hours to get Win Vista installed, and even then, in Vista, installing large installer files (setup.exe or setup.msi) of programs, Vista would timeout the installer after a couple of minutes of 'no activity', while in fact the drive was so slow it could not load large installer files within that time limit.
The drive was good enough for booting an OS, and running software already installed on the drive, and performed much like old 4200rpm notebook HD's found in laptops of around 1996.
It was about 3 times cooler than my current Toshiba MK1234 drive (which I think is 5200rpm).
So in the end it was only good to run Linux from it (with noatime setting on). Those drives in the end came down to about $120 before they got discontinued; most of them where returns to the factory.
