You really should not be installing Windows on an SSD less than 60GB.
If you're going to buy a 32GB SSD read your motherboard specs and see if it supports SSD caching (Intel SRT). If it does then install your O/S on your HDD and use the 32GB SSD as a cache drive.
Your performance will be better than installing the O/S on such a small SSD.
After looking through 32GB SSDs on Newegg and similar sites, I have decided on a 60GB SSD instead(due to less cost per GB). Will I get even better performance with Intel SRT compared to a 32GB? I suppose the main question is: does a larger cache=better performance?
