ZRAID1 pool size beyond expected

I have 3x 4TB drives for ZRAID1 configuration (single parity drive)

After running

zpool create data zraid1 sdb sdc sdd

My volume size is 10.9T, which is my expected stripe configuration, not a RAID5 configuration. zpool status claims it is a raidz1-0 configuration (0 makes sense, this is the only pool on this machine).

Why is my size not 7.2T?

Make it clear: zpool list displays the total number of pools, not the resulting volume size. df -h is correctly displayed as 7.2T.

zpool list displays the size of the pool, that is, the size of all disks. zfs list will display the available file system sizes in the pool.
