How does I/O wear on the SSD? It's all electronic. It does have a lifetime though, as it turns out. A RAMdrive in memory sounds like a better option.
----------------------------
Wear leveling and write amplification. SSD blocks can only survive a limited number of erasures, also known as program/erase (P/E) cycles. Some blocks may host very active data and are therefore erased frequently. Once the maximum number is reached, the block dies. The typical number of P/E cycles is 100,000 for SLC blocks, 10,000 for MLC blocks, and a few thousand for TLC blocks. To ensure capacity and performance, the blocks need to be balanced in terms of how many erasures have been done. SSD controllers have such a “wear leveling” mechanism to achieve that. During wear leveling, data is moved around among blocks to allow for balanced wear out. Partly because of this, the actual written bytes are a multiple of the logical bytes intended to be written, a phenomenon referred to as “write amplification.” These numbers and terms are important to understand how applications can be better tuned for optimal SSD performance.

Some are asking the programmers to reduce GPU checkpointing because of this problem.

Bashing on a flash drive can destroy it. It also has a delicate directory structure.

I had some time off in the previous four days due to thunderstorms, but yesterday was the first full day with GPU, still defaulting to one GPU per computer. That's almost 6,000,000 points

I hadn't tried for more because the GPU frenzy is supposed to end, and go back to 2 GPU every 30 minutes.

The team generated over 16,000,000 points yesterday. GPU does make a big difference.

I sympathize with you. I understand this kind of weather is somewhat of an anomaly for your area. I am guessing there are going to be changes for your power grid in a number of ways. Unfortunately it will probably be reflected in your bills for years to come.
We here did not come through the winter unscathed. Our heating bills will have some surcharges added for the next 12 months or so due to the spot price of natural gas over the winter and costs associated with the midwest power pool.
Every spring I need to get my septic system pumped and I did not have any problems with mine this winter, but the the guy doing the pumping told me they had one of the busiest winters ever due to systems and drain fields freezing. He said some customers had him come every two weeks for a couple of months.
For your sake's I hope the grid operators take whatever measures are necessary to assure their customers there will not be a repeat of this past winter's problems. Probably there is not much they can do about burying the pipes at this point, but one thing you could try if the weather repeats is to leave a trickle of water running which may help keep the pipes open. Of course if your electricity goes out, that probably won't help. I would not wish a plumbing freeze up on anyone.

It took awhile to find where the Forum link was, basically at the bottom of the main page, so that was a bit confusing.

I had one computer change, from a Ryzen 5 to a Ryzen 9, which really added a jump to the thread count.

I had been waiting awhile for Krembil to get things going. I had a lot of medical issues and lost my wife Katherine on March 17, 2023. I had turned off a couple computers and will get them going again.

Hello retsof, my condolences. I installed the client again on a 16 core intel 13 cpu. cheers
