When it comes to solid state drives, it's all about the controller chipset. Granted, the quality of the flash memory used is important, too, but it's the controller chip that makes the biggest difference to both out-of-the box performance and longevity.
For SSD buyers on a budget, that's a problem. Smaller, more affordable SSDs tend to have cheapo controllers. That's probably a false economy given that the cost of any SSD is largely swallowed up by the flash memory itself.
Enter, therefore, Corsair's latest affordable SSD, the Force F40 CSSD-F40GB2. At just 40GB, the new Force F40 is at the very limit of we would class acceptable and usable in terms of raw capacity.
As its name suggests, however, it packs arguably the finest SSD controller currently available in the SandForce SF-1200. Of course, the Sandforce controller does push the price up a little compared to competing 40GB drives. Both Intel's X25-V and Patriot's PS-100 are cheaper. What's more, at 64GB, the Patriot is larger, too.
