Let me state at the outset that this post arises out of academic curiosity and has nothing to do with concern about reaching the TBW rating prematurely.

I'm toying with a new Crucial MX500 1TB SSD by creating partitions with a combination of Diskpart and Minitool Partition Wizard , including system and OEM partitions. Before starting anything else, I ran CDI and it reported zero for TBW, power on hours and power cycle. Then I did a surface scan with HDTune up to 2% which should involve the first ~19GB. Still zero GB written in CDI.

Then I started experimenting with the partitioning. After I'd finished creating 10 partitions (GPT system and OEM), I was surprised to see that the amount of data written had reached 17GB. Today I cleaned the disk and created essentially the same partitions again. Not a single byte of user data has been written but the amount of data written has risen to 27GB.

The only times an operation finished other than near-instantaneously were when I manually set the type IDs of some partitions. These took a few seconds each. Can this be when those GBs were written?
