It’s nice to get away from the bread and butter of this column (laptops and desktops) and look at other things now and then. Like SSDs. They’re faster, quieter, more reliable than their spinning disc counterparts, but they’ve typically been a lot more expensive. Like most things tech, the prices are coming down. The SanDisk Extreme 240GB SSD normally costs $229, but after today’s $60 deal, it’s just $169. For that price you get read speeds of up to 550MB/s and write speeds of up to 520MB/s. This is why Ultrabooks boot so fast; that’s a lot of megabytes every second.
