Forget HDDs, forget SSDs, here come the HRDs

Clear In The DeadPool. So Much For Zipping Through Airport Security

The debate between SSDs and HDDs will rage for years to come, but what happens when a real contender busts in? Now, I’m not talking about some holographic future toy that some physicist thinks might be ready by 2018. The “Hard Rectangular Drive” from DataSlide is a sort of hybrid between a solid state system and a normal platter-based hard drive. Think about a regular hard drive: you’ve got a read/write head in effect zooming around the hard drive, writing stuff onto an unimaginably long spiral. Now imagine if there were a million such heads all lined up, and they just moved up and down a million shorter tracks. Hmm? Sound good?

Well, I kind of oversold it a bit. At the moment, they’ve only got 64 heads running concurrently, but they believe they can work up something that will have many more heads, enabling 160,000 I/O operations per second and a 500MB/s transfer speed. That’s better than even the high-end SSDs — plus, the power draw is only 4W for enough HRD to fill a 3.5″ drive enclosure.

Unfortunately the semi-sequential writing mode means they’ll have to have their own drivers, but if this technology ends up advancing and getting picked up, that should be a piece of cake.
