An SSD is a Solid State Disk drive. These devices are basically flash memory (RAM) designed to emulate a disk drive. They are very fast because they have no moving mechanical parts like an HDD, but they have much less capacity & are expensive. They are being used in high-end laptops because they can make the laptop thinner & lighter & don't use as much battery power (so the batteries last longer).
People w/money to burn are buying SSD's to improve disk performance. I'm going to take a shot at explaining why you're better off putting that money in other places (faster cpu, better graphics card, more RAM). Here goes:
-- Windows caches disk reads/writes to RAM anyway. The only time disk performance is a bottleneck is when you're reading or writing a LOT of information, e.g. when booting Windows or loading a large application. In normal operation, this happens once & then you run your application for a much longer period of time.
-- Assuming you have enough RAM (8GB is plenty) any paging that the system does will be to/from RAM. And BTW, RAM is faster than SSD. If your system is thrashing (paging excessively), you're much better off adding RAM than paging to SSD.
-- SSD's flash memory deteriorates over time. One can argue that HDD's do too, but HDD's last a lot longer.
