windows - A program is using up 150MB/s of disk usage



I get 100% disk usage when it shows 1MB/s, but now I get over 150MB/s!
I know disk usage 100% means you have filled up your hard drive with files, will the files get deleted automatically? What if a program I'm using is filling up my hard drive with 150MB per sec? What happens if I used up 100% disk usage for a long time, does this means my hard drive's life is shorter?



About my hard drive: WD Green 1TB HDD
201GB, 54.2GB free space on C:drive and D:drive repectively.

Hard disks operate using physical movements of disks and heads, and some movements faster than others. Therefore drives can be made 100% busy by doing far less of some actions than others.




I know disk usage 100% means you have filled up your hard drive with files,





No it doesn't. 100% disk usage in Task Manager means the disk is busy doing reads or writes 100% of the time. It has nothing to do with how much space is filled.




will the files get deleted automatically?




Files you manually create are never deleted automatically. Temporary files usually get deleted automatically.




What if a program I'm using is filling up my hard drive with 150MB per sec?





It is not "filling" anything. If that is an antivirus program and it is reading at 150MB/sec, which is normal for an antivirus scan.




What happens if I used up 100% disk usage for a long time, does this means my hard drive's life is shorter?




No. Utilization has no real effect on the life time of hard drives. High write utilisation does have an effect on the life time of solid state drives though.
