News Seagate to Launch Mass Market 20TB HDDs in Coming Months

FIRST sentence of the article:

"Seagate is working on multiple consumer hard drives featuring a 20TB capacity that will use perpendicular magnetic recording (PMR) and shingled magnetic recording (SMR) technologies, "

There will be PMR versions.
SMR sent up red flags.
I’m not familiar with PMR, just CMR & SMR, and SMR is trash.
 
My first reaction: Is it really 20 TB of uncompressed data? How much of that is reserved for overhead? These are the first 2 questions that should be answered about any hard drive before you even know if will fit in your case.
 
"We have a number of different 20 terabyte platforms coming - PMR, SMR, HAMR. There’s a lot of different flavors of them, and they are targeted to different customers so different qualification schedules for each,”

Well they offer a version (not 7,200 RPM) that doesn't have a droning hum into the back of your head 24/7 for those of us that want to use it in a workstation or heaven forbid a desktop NAS?

They still list these drives as having better idle decibel readings than my old 5200 RPM 4 terabyte drive and it's disingenuous at best.
