The new range of solid-state storage comes in the shape of the 2.5-inch v4 drives. While they're slightly slower than their more expensive sibling, the m4, they still offer read speeds of up to 230 MB/s and write speeds of up to 190 MB/s with SATA 2-capable computers. Being 2.5-inch they won't fit in an ultrabook, but they should fit in normal laptops.
And then there's the prices. While $50 will only get you a 32 GB v4 SSD, that may well be all you need if you're planning to run it as a boot disk for your OS to run off, or if you only use your laptop for light work. Either way, installing an SSD will give you a massive speed boost.
Of course, if that's not enough storage, you can pick up the v4 in 64GB ($70), 128GB ($100) and 256GB ($190) versions, too. More here.
