The speed seems to stabilize above 64KB read and write.

My video clips are usually 400,000 kb. How do I relate it to the ATTO result?

A good rule of thumb is to multiply bytes by 10 to get bits. It's actually 8, but it gives you a bit more conservative result and, more importantly, is easier! So 64K Bytes/sec ∼= 640K bits/sec.

Or if you want to be a bit more pedantic, 64K Bytes /sec × 8 bits/byte = 512K bits/sec.
