Elements of HDD construction that impact SQ

[rando]

Wondering if anyone here might have thoughts on impact of Helium/SED/??? on sound quality for a storage or backup drive.  

 

Never stepped outside the rather mundane and proven tech for spinning HDD.  I've looked around for a number of years at cold storage drives etc. without ever trying anything personally.  Honestly I was afraid to commit and find even after running a drive in it sounded awful.  Maybe the shucking lottery holds some good options for our purposes?  +8TB range still seems to be dominated by industrial, security minded, technology.  512e/4K seems unavoidable in a decent drive of that nature.  Which I suspect might be the larger gain over gamercentric/AV focused consumer options. 

 

Any reasonable data points would be welcome.  ≠ everything always makes this fun.
