Question Is it normal my SSD Nvme has 18 times more writes than reads?

So I was checking the status of my nvme SSD I bought in november and Crystal Disk Info says it has 55.638TB of writes and only 3.805TB of reads

Is this possible?, I don't think I've even saved that many info on my PC, my previous SSD that was only 240GB that I used for 2 years, it used to have 50TB writes like a year ago, now it has 111.559TB writes (wow... it was supposed to only have 90TB max writes :grimacing:)

Is there a way to see what is blasting my SSDs with so many writes? the only thing I can think of is Blender, I have the auto save option for every 15 minutes, the avarege size of the files is around 200MB doing some calculation I think since I own the drive it would be around 10TB of data only on blender.

What else could be writing so much?, I want to see if I can reduce the writes, I used more than 1/16th of the total writes in 9 months wow

One last think the PC used to turn on by itself during the night when suspended, I discover 5 months ago it was because there was an option that provoke the system to wake up when a network request is received, I deactivated the option and it stopped, could this be a factor?

The Nvme is: Kingston SSD KC3000, 1024 GB, M.2 2280, NVMe PCIe Gen 4.0
Total Writes: 55.638TB
Total Reads 3.805TB
Power On count: 185
Power On Hours: 201 days 20 hours

Doesn't seem right to me, however you can track what applications are doing writes through the Task Manager. Open Task Manager, go to the details tab, right click on a column name>>> select columns>>>click IO Write Bytes. Order Task Manager by IO Write Bytes. Leave the Task Manager running for as long as the computer is on, at the end of the day have a look at the IO Write Bytes column to see what app is writing the most data.

My anti-virus used to write 1TB of data a day, after 80TBW on a new drive I got concerned and used the above method to identify the cause. I uninstalled it and everything's been fine since.

My system used to switch on by itself too. Can't remember what I did to sort it though. I can't see how that would be...

Thank you!, apparently since I last power on my PC (7 days 5 hours) blender has written 700GB, I'm now changing my autosave timer to 30 minutes to try and reduce it, weirdly enough it also says discord has written 55 Gigabytes! it's really weird why does discord needs to write so much data?, I don't even open many channels, it is constantly writing 30KB per second even when closed (the process is still active only main window is closed)

EDIT: Apparently discord increases the amount of data it writes when interacting with anything, when hovering with anything it goes from 1.5Kb to 400KB per second of writes, apparently discord likes to write a lot!

Glad it was useful, it sounds like those stats are accurate then. It's just a very lopsided figure, on my drive writes are about double the reads. It's surprising how much some applications can write, even web browsers do a fair bit. I tried a few anti-virus apps, the only one that didn't hammer my SSD was Norton. From that link it sounds like there maybe an issue with Discord though that could be resolved.
