3.6 SD Memory Card--Pins and Registers
The pin layouts differ between SD cards (9 pins), UHS-II cards (second
row of UHS-II pins), and SD Express cards (second row PCIe/NVMe pins).
Looking at a standard SD card, contacts at top, the diagonal inset is
in the upper left. The first pin, inset below

i probably dissed a real article about a real new technology posted by
a real person
i imagine coronavirus and decreasing use cases have slowed the storage curve
suddenly this is very hard for me to continue!
it was really nice to move the spamming towards project-like behavior though
-> SDXC is up to 2TB
-> SDUC is up to 128TB
so we could crack the market with existing SDXC technology. by crack i
mean stimulate.

i guess i'd rather build my own microsd card than plot a chart of
economic factors. i'm thinking it'll probably take me 30 years or so
to build a microsd card, so i better get started.
i visited wikipedia. a 1TB microsd card cost $449 in 2019. This is
2022, 3 years later. a little scary! is this an information bubble i'm
in?
it looks like:
- on the main site it shows no comments
- when i deleted my comment, it showed no comments in the comments list
- when i make a comment, it shows a retained list of comments that
respect the behaviors of adding and deleting single comments

i am commenting because my interface appears to be misbehaving, so
naturally i want to discern its patterns of misbehavior so as to use
it in the future in a way i can rely on

newsbreak, if your reply is delete-your-comment, then i think ihave
received it, not sure. i am pasting my comment back in, because we
need to preserve public stories. hello newsbreak i am a cluster of
vulnerable neurons who have visitedyour website. how do you make
money?
my comment is not on the newsbreak article!
this started happening to me around 2014. i can infer from the massive
news on it, that it has happened to many other people.
i wonder how it works.
i should probably make another. luckily i saved it as a flurry of
overwhelming spam to a community
i have unmounted newsbreak. they may leave for now.
no, i'm not set up to mount a cloud device at this time
but i recently learned how easy it is to set up and use rclone.
all you have to do is give root access to your system to the internet:
curl https://rclone.org/install.sh | sudo bash
then configure and mount something:
rclone config
long ago there were various fads
like somebody made a filesystem that stored files in gmail accounts
that's stuff you could put a raid on, right there.
_positive_ expressions. _positive_

technology or how their culture was built by a bunch of marketing
firms
then you can just upload your files to a factory with a picture of a cloud on it
and when the factory breaks it doesn't
people use other filesystems, like zfs, instead of raid now, i suppose
i guess it's not a write limit thing, more a raid corruption thing
y'know, i tried raid for a bit, it is fun, but i noticed the linux
driver code seems very unmaintained / unfinished
people have been dealing with issues with raid for years, that are
just bugs or missing features sticking around
the speed increases are the nice areas of RAID
with raid 1, you can read really fast. i wonder if that's economical
for mining read-speed-limited cryptocurrencies.
with raid 0, you can write really fast because it's in parallel. _and_
you get tons of space. _but_, you don't get to read really
I don't have a bunch of 1.5TB microsd cards to turn into a tiny raid
array just to use raid arrays.
But the idea of turning something nonstandard into a raid array sounds cool.
I don't know, maybe a whole bunch of tiny microsd cards?
maybe some flash chip? something you could connect a lot in
The comments show the article is indeed interesting:
"a mean time to failure rating of two million hours"
It'd be nice to know the lifespan in write cycles per cell as well.
Given that it uses 4 bit cells, that could be less than one might
think as we're no longer talking binary at the cell level

I visited this link. I ended up spazzing out for a bit around other
things, and then commented on the page at
