Given I am now on Day 5 of seamless PT operation, the more all this makes a kind of sense to me.
I hope this helps

I have a 2012 MacPro w/2x 512 Apple SSDs (boot and Samples), and 6 WD 6TB Black Caviars on eSATA (connected via PCIe cards) and a FW800 1TB Caviar for DropBox.

I have ALWAYS disabled spin down on all drives (a habit started since the TDM days of PT). For me this is enabled explicitly in my eSATA PCIe card config, and I have also disabled the PUT HARD DRIVES TO SLEEP WHEN POSSIBLE in the Energy Saver Control Panel.

I am the HDX test contributor who passed the OP test - FYI.
