Samsung Builds Flash Based Disk Drive: "Samsung says it has developed a way to store up to 16GB of data using Flash memory, a development that could lead to extended battery life for notebook and tablet PCs. Flash memory has a power consumption that is five percent of today's hard disk drive, according to the company. These solid-state disk (SSD) Flash-based drives will also provide faster access to data, at about two-and-a-half times the speed of current notebook hard drives. In tests, Samsung was able to read data at 57 megabytes per second (MBps) and write at 32MBps." That's 2-3 GB/Min, comparable in my experience to desktop HD.
"Flash drives also offer the benefit of less noise and heat emissions. They are also less temperature- and humidity-sensitive, meaning Flash-based drives can be used in a wider array of applications and environments. The disk drive itself will look much like a regular 1.8-inch hard disk drive, meaning manufacturers will have to make minimal adjustments to PC designs in order to incorporate the new drives. .. SSD Flash drives based on the new technology are expected on the market by August of this year." They would be useful in off-grid locations, in developing countries or in sensor apps. I wonder if the price will remain at today's $30-50/GB or will be lower. 8:11:30 PM
