If you want BIG performance you have to start looking at exotic builds.
Storage is a big deal right now. Consumers routinely pick up thousands of gigabytes for cheap, and we’re all flirting with cloud storage which requires companies to run tons of redundant back ups. We’re creeping up on the maximum density per platter that physics will allow for packing info on a spinning disc, but other concerns can limit hard disc storage as well.
Namely air turbulence.
Yep. High performance drives spin up quickly. That 7200RPM badge on the side of your drive is commonplace these days, but that’s still pretty incredible when you think about it. Every second the platters are rotating 120 times. Those platters are designed around a certain fault tolerance and thermal envelope. Run them too hot too long and they’ll fail.
We’ve already posted about the new “shingled” array that Seagate and WD will look to use to pack more info on a drive, but that comes with certain sensitivities. Also, with each improvement in storage density comes the risk of losing even more data in the event of failure. HGST looks to improve run time and durability by hermetically sealing the drive in an envelope of Helium.
Helium is lighter than air, so there should be less resistance and turbulence. Less turbulence means less power is needed to spin the drive up, which results in less heat generated and a cooler operation temperature. Cooler temps should deliver long life cycles. It’s a very interesting solution for providing a more robust storage architecture. This kind of big storage affects every kind of service we use online today from social networking to streaming video.
HGST says the drives are “generally available now”, but bxpect the first applications to be for corporate storage. I wouldn’t be surprised to see these drives trickling out into consumer grade workstations next year.
Full PR after the jump. Continue reading “Western Digital owned HGST turns to Helium for 6TB hard drive”
