Different Operating Systems use different amounts of disk space to store their metadata. Therefore, formatted disk space is always less than unformatted disk space. Another thief of usable capacity is overprovisioning. Overprovisioning is taking usable storage of a SSD for use by the controller. This space is no longer viewable by the user and is used mainly for wear leveling, metadata and spare sectors which improve the life of the overall SSD.

Now, let us take an example of an organization looking to add capacity to their storage infrastructure and break it down into how it can play out.
What can happen is that your business units will then start to try and claim amounts of storage for their projects based off this number, and before you know it, various business units claim all of the 60TB. However, you never really had 60TB to work with. So, in our earlier example with 60TB of raw capacity, your usable capacity may end up being closer to 36TB, which is a considerable difference and may affect how your business units claim various storage amounts.
So there we have it: clarity and choice. You are commenting using your WordPress. You are commenting using your Google account. You are commenting using your Twitter account. You are commenting using your Facebook account. Notify me of new comments via email. Notify me of new posts via email.
