HGST Debuts Ultrastar He10 10TB Helium-Filled Hard Drive

I bet you never thought you would live to see the day we had 10TB hard drives did you? Well, helium-filled hard drives have finally reached this point by creating the first 10TB hard drives that use conventional recording methods. Western Digital subsidiary HGST has created the Ultrastar He10 which, interestingly enough, is not the first 10B helium drive. HGST created the first real 10TB hard drive back in the summer. However, this new drive is the only helium drive that has 10TB and uses perpendicular magnetic recording (PMR), the standard recording technology for hard drives over the last 10 years. The first 10TB drive from HGST used shingled magnetic recording (SMR). SMR uses magnetic tracks that overlap to increase capacity. The downside here is that there is very little guard space between the tracks, which makes rewriting data much more difficult and longer as adjacent tracks may need to be rewritten as well. That is why SMR is better-suited for cold storage as opposed to routine
