WD My Book Thunderbolt Duo 4TB review: lightning fast?

External drive with very fast connection


Performance - AJA System Test

Like the Black Magic Speed Test, the AJA System Test is very good at analysing the transfer rate for video editing. We went with a 4GB test file with 4096x2160 10-bit RGB video frame. We ran the test in both RAID 0 and RAID 1. In RAID 1 we got 108.5 MB/s for writing and 108.2 MB/s for reading.
