Solid-state drives cost just a fraction of what they did a few years ago, but with prices that can still exceed $1,000, you could hardly label them as cheap. Crucial still aims to put solid-state storage within reach of those on a budget, however, releasing its 2.5-inch v4 drive with pricing that starts at $50. That entry-level model will net you just 32 gigs of storage -- hardly a lust-worthy sum -- but the series is also available in configurations of 64GB ($70), 128GB ($100) and 256GB ($190), offering read speeds of up to 230 MB/s and write speeds of up to 190 MB/s with SATA 2-capable desktops and laptops. The v4 joins Crucial's higher-end m4, which offers much speedier performance and Ultrabook-friendly configurations to boot. You'll find full details in the PR after the break.
