A few weeks ago I watched as show about the evolution of disk storage (I believe it was on PBS) and Im amazed how these technologies evolved and its impact on computing technologies. Through the years the program showcase how technology moved from a room full of capacitors and gigantic magnetic plates to a quarter size storage medium.

Yesterday, Cnet reported about this new high-capacity flash drive from SanDisk which the company believe would later on replaced the harddisk of mobile device.
Unlike traditional hard drives, flash memory drives do not contain moving parts. As a result, flash devices are less prone to breaking down—flash cards can survive drops from great heights—and consume less energy. SanDisk’s flash drive can increase battery life by about 10 percent, said Doreet Oren, director of product marketing for SanDisk.“
I totally agree. Although this new storage device will be more expensive than your current 2.5” hard drive is I think understandable but later on as more and more company adopt the technology we would expect the cost will also go down. But for now don’t drop those hard drive.. yet!
