What the speed of Thunderbolt 1TB Seagate drive H8683ZM/A using Blackmajic Disk drive speed test?

The BlackMagic Disk Speed test utility (version 2.1) gives me the following speeds:

109.0 MB/s write, 109.8 MB/s read. This is for the hard drive included in the package (a 5400rpm drive).

I ran some comparison tests as well. Using this adapter with a 500GB Seagate GoFlex Pro for Mac (STBB500100 - came with the FW800 and USB 2.0 cables), the speed was:
78.3 MB/s write, 82.4 MB/s read. (This is a 7200rpm drive).

For the 750GB Toshiba MK7559GSXF that came standard in my MacBook Pro 8,2 (which is connected to the second internal SATA port in lieu of my optical drive), I only get 69.7 MB/s write and 70.3 MB/s read.

So, I have to say I'm impressed with this drive. It works well with the other USM drive that I own, but it's fastest with the new drive.
