I read late yesterday evening that the Chia plot process will make a major change.

Until now, plot creation has been done strictly on CPU's. The creator(s) of a console program, called Madmax, will soon add GPU code. OpenCL, I believe it is. In time, their GUI application will follow suit. Individual plots are 101 GB and change. Through my own experimentation, I learned plots can take 3 to 12 hours to create, depending on the CPU and storage types.

Imagine reducing the calculation time to 20% of what it is now, or even less. Drive read/write times would become the largest bottleneck. Most of the people running this are using large SSD's as working drives. Finished plots are written to a final location on a large mechanical drive. If plot creation time, including final writes, drops to 25% of what it is now, the demand for more and larger drives will soar beyond what it is now.

I believe the demand for smaller drives, <= 1 TB would stay at a normal level. Those of us participating in the GIMPS project would not need anything larger in our home system(s). Those running special projects might need more and larger. GPUto72, for example. I keep a few 250 and 500 GB's around for replacements, if needed.

Note: When anything new, like this, comes along, I study it in great detail. Basically, I want to know how it works. It gives me something to do and keeps my mind busy. Being retired, I need this.

Personally... I have found that those who are serious in their work never retire. Until, of course, they die.

Be it a pilot, an engineer, an architect, or a manager, there is something to be said for experience.

Ye still young and fresh. Talk to us about that when you'll reach retirement age. One step, one fart...

Not all people have a job that they even COULD do past a certain age. It is easy for politicians to extend the retirement age : they can keep on doing their "job" until after becoming senile, one would even say after dying ;-) I would like them to do some factory work, cleaning, nursing, construction work before assuming people can keep working almost indefinitely. The body ages... Some non physical work can also be wearing : the job of call centre operator is not hard physically, but few people can resist the strain, most quit after a a time, long before retirement age.

I agree. Heck, just look at the burn-out rate of those responsible for Cybersecurity work! It's not for the faint of heart.

I should have been clearer in my above... At least for the small sample set that I have, I have found that very few people actually retire from doing interesting things with the skills they have learnt over their many years.

Often in completely different fields of expertise.

Agree with S48, which does not sign his posts "Jacob" anymore.

Talking about jobs that are not physical, but completely wear you out, I recommend you all the movie "Pushing Tin" (one of my favorites! I love Billy Bob Thornton's character in that movie!)


Edit: Crosspost with Chris. Now, you two are fighting, or kissing? Did I pay the ticket in vain?

Another Reddit snip: 84 drives. 14 TB each, so the owner claims. Most of these people like Seagate Ironwolf NAS drives. Amazon lists them for $650 U.S. each. I do not know anyone with $55K U.S. laying around...

Really? All I hear is people ing all over Seagate drives, I've had far too many fail on me.

16 TB Toshiba MG08 drives for me, based on the reliable HGST 3.5" drives. Selling on Scan.co.uk for £340 right now. Edit: And £315 on Amazon.

Not only are they great drives, I don't know of a lower price per TB at the moment. That said, even at this price and with current Chia network size and value, it would still take about 1.5 years for a single drive to pay for itself in mined Chia coin so it isn't currently worth buying new drives for plotting, and I suspect this is why the network size has levelled off.

I had a single 3 TB HGST drive several years ago, which I returned. It got so hot I could not touch it. I felt its life would be rather short.

I don't have any Seagate drives. The few I have are Western Digital. I bought an older HP workstation a few years back. It came with a blank 250 GB WD. This drive began to fail not long ago. The manufacture date on the sticker said 2011. CrystalDiskInfo indicated it had 56,300 hours and change on it. The "uncorrectable sector count" was very high, like in the hundreds. I was not aware anything was going on this it until I saw an error on the screen. The highest mileage WD I have now it a "Black" 500 GB. I used it as a boot drive on my primary system until Windows 10 became so bloated that it seemed no longer practical. The drive has about 38,000 hours on it. I went to a SSD.

I have had Seagate drives in the past. I had a matched pair of 500 GB's. One died with 28,000 hours on it and the other at 33,000. I had them for 8 years so I didn't feel bad about it.
