Recently there has been a surging demand for solid state drives that sacrifice space for speed and more affordable price tags, and manufacturers have been racing to deliver just that. Most of the drives featured in this round-up offer 32GB - 40GB capacities, while a few others top out at 64GB. As limiting as a 32GB drive might appear, they can still be extremely useful in enhancing a PC's performance when set to run as the boot drive. These smaller drives can also accommodate for select programs where they can greatly speed up the use of the application, for example, Adobe Photoshop.

Today's round-up is comprised of the following contenders: OCZ Agility 2 40GB ($135), OCZ Vertex 2 40GB ($124), OCZ Onyx 64GB ($130), OCZ Onyx 32GB ($85), ADATA S596 Turbo 32GB ($83), Intel X25-V 40GB ($100), and the Kingston SNV425-S2 64GB ($125). In addition to these affordable SSD offerings we have added to the mix the Seagate Momentus XT ($135), a highly-touted hybrid drive that attempts to deliver the best of both worlds by offering huge storage capacity at a reasonable price, with the added performance boost of NAND flash memory for caching data.

We'll be putting each drive through a set of tests including four synthetic benchmark programs plus our own file copying and load time tests.
