Humidity in a helium HDD?

[fzabkar]

This thread has a FARM dump from a Seagate ST12000DM0007-2GR116 helium drive:

The drive reports a relative humidity of 17.5%. How is that possible?

does it say anything about the temperature? I guess that's the key factor here.

Yes, there are temperature stats, by how is it that there is humidity in the HDA? I thought the environment was pure helium. Am I wrong?

What is a helium hard drive?

A helium hard drive is a hard disk drive (HDD) with an internal enclosure that is filled and hermetically sealed with helium gas rather than oxygen.

<sigh>

The internal enclosure of today’s helium hard drives is hermetically sealed using sophisticated engineering and manufacturing techniques pioneered by Western Digital.

this is also bullshit, they bought out HGST and use their technoligy up to date...

I have several helium disks which is the way the industry started increasing the platters in the assembly. My old 12TB is HGST and the disk is fine even after many operating years. My larger disks are WDC but I am looking at Seagate for Exos offerings now.

None of my helium disks have lost any helium and humidity is misleading as helium disks are sealed.

WD's 32TB disk has 11 platters while Seagate's is 10 platters. WD has developed new 14 platter technology which can bump capacity by 27%. WD is expecting to offer 40TB disks later this year. 40TB disks could handle a lot for consumers too.

The current 32TB disk is plenty for my game library but buying a few can allow me to back them into a TAR backup.

The 40TB is still being sold to cloud operations so it may be a while before these are available. There is also talk of 44TB and larger capacity hard disks next year.
