[clug] Disk size

[Eyal Lebedinsky]

I thought we need some comic relief after the recent fun on the hill. Not Linux specific but...

For a while now I noticed that recently acquired USB disks offer less storage than advertised.

For example, a 32GB disk
	SanDisk Ultra USB 3.0 Flash Drive 64GB
provides (as fdisk tells)
	Disk /dev/sdj: 57.9 GiB, 62109253632 bytes, 121307136 sectors

A smaller one
	SanDisk Ultra Fit USB 3.0 Flash Drive 32GB
has
	Disk /dev/sdj: 28.7 GiB, 30752636928 bytes, 60063744 sectors

I just now saw a message (unrelated) on the linux-raid list mentioning:
	"I should note that for some reason the "32G" Optane only has 29.260 G
	bytes (27.3 GiB)"
So SSDs are afflicted too.

What is this trend? The GB/Gib excuse ran out of steam? What is it now?

Will disk space collapse into a black hole and become a write-only medium?
