That is odd since the max read speed for the drive is below 300MB/s. Is this a bug @Steve ?

Hmm... I see your interface speed is spec'd at 600 MB/sec. That is SATA III. Your device benchmarked at 541MB/sec at 50 and 75 % so it is SATA III also.

@Lumbis if you are referring to the speeds that are closer to 600MBps; according to the drive spec it's a Shingled Magnetic Recording (SMR) drive. This would mean that the firmware knows there's nothing in the 50%+ regions of the drive and therefore just reports back instantly at the maximum speed possible. If data were to be written at that region we would start to see a true reading.

Oh I see, that is good and to know. Which that was made clear in the software/GUI.

That's a hard one to accomplish as there are probably a few things that fall into the category of - it would be nice to see this in the interface. The more that's added the more cluttered it becomes.

If it was easy to figure out which drives are SMR and which drives aren't and then produce the message accordingly perhaps that would be a good change. But then I don't think it's easy to surface that information.

At the moment there are enough people that have been working with Steve through this process and can probably answer it in the forum's if it ever gets posted :).
