Theoretical Throughput

[jvioncek]

I have what I hope are a couple of simple questions:

If I have 4 drives that are capable of 250MB/s sustained sequential reads in 2 vdev mirror configuration (RAID 10), will I end up with 500MB/s of theoretical throughput?

If I add another vdev mirror (2 more drives) will my theoretical throughput then increase to 750MB/s?

Theoretically 2 mirror vdevs(4 disks) should give you 1000MB/s since you can read from all drives at once.
