As Scott has mentioned, yes that is correct.
For reference there is a handy table within the Storage Management Guide:
This gives a 2TB disk as:
|Disk size as described by manufacturer||Physical capacity (approximate)||Usable capacity|
|2 TB SATA||1,695,702 MiB||1,695,466 MiB|
For the full how and why, KB 3011274 covers it:

Ok. Just wanted to make sure this was correct before I started using them. That would explain why they sent us 96 drives to satisfy a 100TB usable order.

You should get about 110TB usable without snapshots… an example layout with 18 drive raid groups (leaving 6 spares..more than you need but not enough for another complete raid group) assuming all on the same controller but you could split between controllers.
TB Usable no snaps

Thanks for the info. We split them between 2 controllers in an active/active cluster, so there were 48 disks per controller. Some were used to expand an existing aggr and the rest were grouped into a new aggr.
