Reliability of helium based hard drives?

4 posts in this topic

Now that helium hard drives have been on the market for a couple of years, would you consider them to be as reliable as existing "conventional" hard drives, more reliable, or less reliable?

 

Will the helium inside eventually leak out?

IIRC the only one with enough data to be statistically relevant (and even some of their collections of specific models it isn't really large enough to be relevant) is Backblaze...

They only have a tiny, tiny handful of enterprise disks that are helium filled so don't read too much into it, but between Backblaze data and what we are seeing, I'm not seeing any concern for long-term reliability of helium filled disks.

Talking with HGST, they think they're more reliable. They are the only ones who would really know, but take their data with a grain of salt.

HGST's consumer grade drives are rock solid for reliability, and their enterprise drives are really reliable.  Working in pro data recovery we strain our drives to the max with constantly moving around full HDD's worth of customer data, image files, etc.  For our high-speed RAID arrays which we use to store and process all this data, HGST enterprise drives are all we use because we'll kill pretty much anything else in a matter of months.

As to their helium filled drives, we generally don't use those.  While I'm sure they are reliable, part of the reason they went with the helium is so they could stack more platters and thinner ones in there.  More platters = more read/write heads = more chances one will fail.  But, even most enterprise customers aren't going to strain drives like we do here.  We move Tb's of data around every single day.
