It isn't often that the capacity of the hard drive increases, but today we were lucky enough to receive the first 6TB HDD in production. The HGST He6 is a filled with helium to allow for thinner platters and a number of other advancements, including lower power consumption and weight. This is a drive destined for the datacenter, but all technology tends to eventually bleed down to the consumer space.
We took a closer look at the new He6 architecture in this article. Head there for a deeper understanding of the new He6 Helium HDD's.
Its easy to get jaded when you test storage for a living, but this new drive really excites me. We are working on a full evaluation as you read this, which is now posted here. The Ultrastar He6 is destined for datacenter applications that require the utmost capacity and efficiency and is designed accordingly, so any initial impressions should be taken with a grain of salt.
Note the tight grouping of these latency results in this test. This is very consistent latency for an HDD.
