Photo: Andrew Liszewski - Gizmodo Technology gets faster, cheaper, and more capacious year after year, but every once in a while it still manages to catch you by surprise. It wasn’t too long ago that 4TB of storage required a RAID enclosure claiming a corner of your desk, but Crucial’s new X6 4TB portable SSD packs that much storage into a palm-sized drive that doesn’t seem like it should actually exist. Advertisement Big bumps in storage capacities always come with a premium price tag at launch, and Crucial’s new X6 4TB SSD is going to set you back $490 if you run out and buy one right now. By comparison, you can get a 4TB portable hard drive right now for about $90 if you find a deal. (Good news—they always seem to be on sale.)
