A company named DataSlide has presented a new type of mechanical HDD that could bring massive improvements in performance and power efficiency.

The company is developing what it calls "Massive 2D Parallel Storage Technology," which effectively takes the spinning disk of a standard HDD and turns it into a two-sided rectangular plate. That plate then slides in between two surfaces containing arrays of read/write heads, one head per sector. With no arms to zip around DataSlide is projecting up to 160,000 operations per second and 500MB/s transfer rates, numbers that blow even the fastest SSDs out of the water, and power consumption of less than four watts. That the heads and the storage are actually making physical contact all the time is disconcerting, but a diamond coating pledges "years of worry free service." Yes, diamonds, the things able to scratch just about anything else on the planet -- sounds like a great lubricant to us.
