200GiB? So like <= 8TiB/100y @ 1Mtx/d @ avg tx size ...? No problem.
Fiddle with the avg tx size / rate, see what other numbers pop out.

There are always sweet spots and tradeoffs...

SD is obviously native form factor than HD and SSD
for use in personal carry hot wallet devices like phones.
USB is a very useful medium.
Does anyone make USB drive to SD slot adapter?
> SD cards aren't reliable - HDs are cheaper and better.
Flash bits are quite good, flash and spindles just
have different failure modes and vulnerabilities.
Most user's far greater weakness is not their media,
but their usage, crypto, and backups.

Determining what was said gets harder as time goes by,
and some are releasing their own private bits on blogs
and sites that never get pulled into larger archives.
Here's a couple archives...
"a few servers in a datacenter"... sounds fatally cerntralized.
Not everyone's first / last saying, or reported interpretations
of same, is right, or unchangeable.
