There are a number of enterprise storage systems optimized specifically for SMR drives. This is targeting actual data centers, not us humble homelabbers masquerading as enterprises.

Real or Cake?

I feel like this could work using a tiny generator attached to the drive’s motorized wheel, but that’s probably too complex to be cost-effective for something like this unfortunately.

What would be the point of streaming a game at 4K onto an 800p display?

Yes, but what if it were a subscription? May I present: /dev/null-as-a-Service.

Would have to be cat /proc/sys/kernel/random/uuid > /dev/null

You can’t pipe to a file, only to programs, and since /dev/null isn’t an executable your command will simply give an error.

To make it more clear, consider using dd, which lets you explicitly specify an input and output file. For example: dd if=/proc/sys/kernel/random/uuid of=/dev/sda1 wait shit that wasn’t the right output oh god oh fu

Trading has nothing to do with cryptocurrency mining. Also, any high-frequency trading firm worth their salt is using FPGAs for the things where performance really counts.

Additionally, give this man a red hat and he would be the world’s greatest Santa Claus.

There is nothing nuclear about microwaves.

Making more wallets would cost nothing more than a few hundred bytes of storage each for the keys. I have no idea why they wouldn’t have split their funds into evenly sized wallets of, say, $1M each.

The Penguins of Madagascar is much older than Top Gun: Maverick, how could it the show have referenced a movie from the future? Or did the original commenter mean the original Top Gun?

I was thinking it’s from The Penguins of Madagascar, Skipper says “just smile and wave, boys, smile and wave” practically once per episode.

Only if the old software happens to have drivers compatible with the new hardware, which it almost certainly doesn’t.

25% of millions of people is still many people, they didn’t say “a majority of people”.

You’ve made me uncertain if I’ve somehow never noticed this before, so I gave it a shot. I’ve been dd-ing /dev/random onto one of those drives for the last 20 minutes and the transfer rate has only dropped by about 4MB/s since I started, which is about the kind of slowdown I would expect as the drive head gets closer to the center of the platter.

EDIT: I’ve now been doing 1.2GB/s onto an 8 drive RAID0 (8x 600GB 15k SAS Seagates) for over 10 minutes with no noticable slowdown. That comes out to 150MB/s per drive, and these drives are from 2014 or 2015. If you’re only getting 60MB/s on a modern non-SMR HDD, especially something as dense as an 18TB drive, you’ve either configured something wrong or your hardware is broken.

This is for very long sustained writes, like 40TiB at a time. I can’t say I’ve ever noticed any slowdown, but I’ll keep a closer eye on it next time I do another huge copy. I’ve also never seen any kind of noticeable slowdown on my 4 8TB SATA WD golds, although they only get to about 150MB/s each.

EDIT: The effect would be obvious pretty fast at even moderate write speeds, I’ve never seen a drive with more than a GB of cache. My 16TB drives have 256MB, and the 8TB drives only 64MB of cache.

My 16TB ultrastars get upwards of 180MB/s sustained read and write, these will presumably be faster than that as the density is higher.

not sure what you’re on about, i have some cheap 500GB USB 3 drives from like 2016 lying around and even those can happily deal with sustained writes over 130MB/s.

It is the point, this is exactly what Broadcom does.
