Solid-state drives are wicked fast. They’re also expensive and (at least for now) limited in total capacity. So how do you get the performance benefits of an SSD upgrade without breaking the bank?

The trick is to look at the total amount of space available on the system drive and then make intelligent, case-by-case decisions on where to store different kinds of files.
