Im still very confident that the software is not able to read the data correctly. Evidence via testing methods used is not always necessarily accurate. Learned that years ago.
Got a tip for us?

This increasingly resembles some kind of religious sect.
Smartmontools is an open source application (https://www.smartmontools.org/browser/trunk/smartmontools). So anyone can check, verify and debug it.
The NVMe specification is also not secret and is available to everyone here.
Anyone can read how to get TBW (just read a few bytes of data provided by the device firmware).
as someone who uses lightroom heavily, and looking to get a new Mac strictly for lightroom/photoshop almost; does this change at all if keeping the catalog on an external drive maybe? Not the photo directory only, but the actual catalog itself.
This is exactly why I went with 16GB of RAM on M1 vs 8GB on Intel even though my testing shows 8GB is more than enough. I also had the 8GB Vega 48 on my iMac. So if my software needs to pull that 8GB GPU, I still have my 8GB of system ram available.
Source? That is the whole point of unified memory. Otherwise how are the Mac Pro systems ever going to be replaced?
Checking RAM usage while VRAM indicator in iStat is maxed out. I don't know if it's exactly 2GB but it appears to be somewhere in that range. Already tried finding some information regarding this in IORegistry but so far no luck. Regarding Mac Pro, Apple can always increase that limit. And I highly doubt the M1 "Big Mac" will come with an IGPU only. There will be dedicated GPUs with dedicated high bandwidth memory for sure.
There is no dedicated VRAM and System RAM now. The GPU should be able to access any of the 8 or 16GB.
No effect,
My library is already in an external NVME drive via usb 3.2 10G connection.
It look like the M1 mac is swapping video to ram.
My intel machine does not manifest this issue.
while i agree, 8GB simply isnt enough when you cant upgrade down the line; however people with 16GB are also reporting tons of TBW
I have had both for weeks side by side, the majority of the time 16gb cruises without hitting the SSD
not saying i disagree, it makes a huge difference in normal day use. Just saying its still an issue. I see some numbers (both in this thread, or elsewhere, redidt, twitter, etc) where 16GB models are getting absolutely crushed still. Think its a mix of what specs and usage people have.
I know for me, who is wanting a new M1 mac and a heavy lightroom / photoshop user, its got me cautiously waiting for an answer from Apple. As lightroom seems to be doing massive TBW, classic (not optimized) or cloud (optimized) dont make a difference. I think adobe has acknowledged a memory leak on their end, so maybe that helps.
So what evidence would you accept? What are the "proper" tools to analyze this?
I have 40GB of RAM and I've been following this problem for months. My late 2017 iMac which I purchased in December of 2018 has astronomical read/writes - and I'm on a 256GB SSD Intel Core i7, already at 60% Life Percentage used.
I myself too use heavy AE, FCPX, Photoshop, Illustrator and Cinema 4D - all which take up the majority of the SSD disk space.
I'm not waiting on any form of evidence, as for proper tools, only time will tell.
Do you realise that this SMART tools data is completely coherent with what macOS reports in Activity Monitor in regards to data written by `kernel_task`? For people who have workflows creating conditions necessary for this to occur that is, i.e. memory intensive workflows.

Is it ok in your opinion to have ~~0.5 TBW by just reinstall system and updates? Lets say that Big Sur takes ~~100gb (which would be INSANE) and OS updates another 100gb (lol).
Where the rest 300gb came from?
same here
it seems like macos writes some apps directly to the SSD completely skipping RAM (this is a joke)Is it ok in your opinion to have ~~0.5 TBW by just reinstall system and updates? Lets say that Big Sur takes ~~100gb (which would be INSANE) and OS updates another 100gb (lol).

It was several reinstalls though since the procedure wasn't well documented early on but now that this issue has been brought to light I'm keeping a closer eye on disk writes under normal day to day use and so far it's still at low ~500GB disk writes on a device with 16GB DRAM.
The issue doesn't exist on Intel based Mac's with Bigsur.
I have Mojave on my iMac (late 2017) and I'm experiencing this problem.
