"New flash-and-platter architecture offers 'breakthrough in storage that
works differently,' firm claims"

I wonder if the 50 TB drive will come in a 3.5 inch form factor ? And
what the price will be ?

I'll take a pair. I don't really care about the form factor as long as my
PC(s) have a compatible interface. I suppose the initial price will be
$unobtainium but it should eventually come down, especially when they start
to focus on whatever comes next, perhaps a 100TB version.

Interested in this paragraph:
"It used to be, not that many generations ago, that you could write 10,000 times before needing to refresh sectors on either side," Western Digital engineering fellow David Hall explained in an interview for the company blog. "And then as we pushed the tracks closer and closer together, it went to 100, then 50, then 10, and now for some sectors, it's as low as six."
Are they talking about non-shingled drives?
So if I have a Toshiba 14 TB drive, it needs sectors refreshed sooner or later?
