I have been given a new computer from my employer.
It has a 2-drive design: a 128GB ssd and a 1 TB HDD.
I have 'download' folder mounted on HDD, also my virtualbox VMs run from HDD but initially (for about 2 weeks) were runing from SSD.
How it's possible it reached more than 30 TiB written in just a month?
Actually 34500 GiB in 365 hours.
PC is HP-Pavillon 16GiB of RAM and drives as above
I just left it as it was 'out of the box' editing just this:
pagefile -> was on C: (Now I moved on D: that is HDD)
Download folder -> moved also to D (via windows utility)
Virtualbox-> installed on C (first machines were created there), once I ran out of space I moved (with Virtualbox utility) to D also.
I noticed that few machines still keep their snapshots on C even if migrated on D with Vbox tool.
In virtualbox I have 20VMs
EDIT: Crystal Disk Mark also reports 0x86E9 in 'lifetime writes from host'
