Maybe in the future, someone will invent self-expanding storage -- a hard drive that increases in capacity when you fill it up. That'd be cool, wouldn't it? Sadly, such technology doesn't yet exist, but on the bright side, HDD storage is pretty affordable these days. For example, check out today's top deal for a Western Digital 1TB IntelliPower 3.5-inch Internal Hard Drive for $60 with free shipping (normally $77 - use coupon code: [EMCPHHB26]). WD is pitching this drive at AV buffs who need 24/7 reliability for always-on video streaming. It has 64MB of cache and various technologies like Preemptive Wear Leveling (PWR), which makes the drive arm frequently sweep across the disk to reduce uneven wear on the drive surface common to audio and video streaming applications.
