To answer your questions, please read below:
1- All of our drives come with over-provisioning space, which is not included in the advertised capacity.
2- For you to be aware, for a 400GB SSD, the size reported by Windows* is 372.529GiB
- For the 480GB, the capacity reported by Windows* is 447.035GiB
This is not the over-provisioning space difference, the data center drives come with around 15% over-provisioning space and the consumer drives with 7%.
