I was examining a new hard drive when I noticed something peculiar:
It's a 1 TB HDD from Seagate, and CrystalDiskInfo shows that it supports TRIM! AFAIK, TRIM is some SSD feature that allows the controller to recycle and erased unused pages for better write performance in the future. But HDD just overwrites the old data and doesn't need any "deletion notify".
What does this TRIM support on an HDD indicate?
