Data itself has no weight. What represents it in different media may.

But data has 0 value, it ceases to exist, if it is not stored in a retrievable manner.

Does that mean we can only store 1s?
How is null stored?

Only 1's. What? You want to store 0's too? How many? LOL.
The two states of the typical flash memory cell are charged and uncharged.

Certainly. How many depends on the data.
When a cell that contained a 1 could be overwritten with a 0.
But your statement But data has 0 value, it ceases to exist,... confused me.
What ceases to exist? The data? A 0 ceases to exist?

I'm sorry I worded that oddly. What I meant was, in general terms, if data is not stored, then it ceases to exist, and when it ceases to exist it has 0 value.

Last I knew, there was data, 0s and 1s, and null was no data where 0s and 1s are indeterminate or irrelevant.
How do you know null is 0s? It could be 1s. Depends on the logic system. Positive Logic is active-high and Negative Logic is active-low.

Which weights more, a 4GB HD freshly formatted from the packaging? Or, that same 4GB HD with all my TIFF, RAW and the LRCAT files filled to 3.66GB?

The full one but the difference is not measurable.
My point was the mass of the storage element should be considered because without that there is no data.
Have a Merry Christmas.

HD or SSD?
Then data has electricity also, for without it, there would be no data.
Merry Christmas to you also!

If you are talking about JPEG file size then the file size depends a lot of the complexity of the image. Merging images create an image with more complexity than one single image in the group used to merge.

Sorry if my lack of technical knowledge disappoints. I wish I had more time to learn some of what is clearly second nature to you.
As I think I wrote a couple of times in this thread, I'm using a Nikon D850. Unfortunately, I felt a couple of days ago that I just don't have the knowledge to communicate to you the problem, but I came back chiefly to thank you.
Yes, the 45.7 megapixel camera often produces larger than 45 MB RAW files. And why a 60 MB RAW file gets transformed into a 30 MB file through Lightroom's Develop function and/or Export as a jpg, beats me. I can almost swear that was not the case, before my Lightroom 6 somehow began behaving badly.

45.7 Mp camera, the total amount of pixels in the sensor.
The file will not be 45.7 Mb.
Apples and kumquats. Pixels<>bits(bytes).
The file size for a 45Mp image will usually be larger because there is much overhead information in the file in addition to just the image data.
JPEGs created are smaller in bytes because the data is compressed, depending on the amount of compression selected during the save ("quality" level).

Well a byte is digital data and as such it must occupy a physical location. That location is not 0 mass. Be that a hard drive or computer memory, there is a physical location where that byte is stored. On computer memory is silicon, it has mass, on spinning rust it is the platter and IronOxide, which also has mass. HD's are TB sized now but a few years ago they were GB and before that MB sized. A GB would be a lot of those! So a GB of data definitely has mass, i.e., weight.
Thanks, BTW. That was obvious to me from the outset. I simply began calling MB and GB and TB "weight" years ago, just by understanding that electrical connections have mass. (E=MC squared. Energy is matter or vice versa.)

JPEGS are compressed files. A 60MB raw file, which was cropped, and then exported as a JPEG, could end up asa 30 MB jpeg file.
