Modern disk, tape, usb, ssd, etc...
Some of them now show different read or write speeds
depending on whether zero or random data was read or write
from them... (users may need to eliminate system/random bottleneck
by pregenerating random data into say 1GiB file on ramdrive source
and going to/from there, /dev/null, /dev/zero.) Not since decades
ago advent of badblock management in firmware has zero been
even a remotely trustable method, now it's even worse.

Minimum, effective, simple, at-rest data security protocol
for the masses is now...

buy drive
dd if=/dev/random of=drive bs=1m
encrypt drive
use drive
destroy key
dd if=/dev/random of=drive bs=1m
reuse or destroy drive

None of today's CPU, NIC, plugin-hw, networks [1], etc are
even the slightest bit trustable, at all, period.

So while that protocol will always be needed, you really must
start improving the hardware situation by routing around and
displacing the old top-secret owners of the legacy system
with completely new models...

#OpenFabs , #OpenHW , #OpenAudit , #FormalVerification ,
#CryptoFunding , #OpenTrust

High demand exists for a magnitude shift in HW trustability,
a new open platform... total greenfield, highly profitable
to whoever does it first, free-market voluntaryism at work.

[1] While you're at it, lay your own P2P fiber/RF meshnets too.
The legacy internet has refused to encrypt and fully chaff
all its links, and censorship spyveillance control is rampant.
So now you must route around that too with something much
better, built by, for, and with openhw components piecewise
owned and operated by... you, the individual users, outside
central control, p2p, together in freedom, decentralized
distributed encrypted, all around the globe.

The economics of these things are all now possible,
saved from cancelling decade of monthly subscriptions,
crypto crowdfunding and even share ownership via
privacy-enabled cryptocurrencies DAO's, etc...

And of course, FreeBSD runs on and powers part of it too.

Free your mind, get started, have fun :)
