Just a quick update as I haven't loaded anything to the drives yet and am still running some experiments, but I put 3 Samsung 2TB hard drives into the Icy Dock that I purchased.
They were on sale, so $80 a drive from NewEgg and another $180 for the Icy Dock.
The Icy Dock is well built, but the drive trays were a bit flimsy without the drive actually loaded into them. Not a big deal, and the drives went onto them easily. One I mistakenly put on upside down, so I had to correct that (easy) but just be aware that it's easy to mess that part up if you aren't paying attention.
The three drives slid right into the chassis, locked in place, no issue.
I then used the supplied USB 2.0 cable and connected it to the Dune Base 3.0 and plugged it in.
It took a couple of minutes for the Dune to recognize the drives, but they showed up on the main interface of the Dune without me having to do anything at all. They were just 'there'.
I had NOT formatted the drives and when I went to the drives on the Dune they were not browsable. The Dune indicated that they likely were not formatted and asked if I would like to format them as EXT2. I said "Yes" and it let me know that it would erase all data from the drives. This was fine, so I confirmed that I wanted to do this.
It took about 8 minutes per drive to format to EXT2 and I had to repeat the same steps for each drive.
It gave me some funky long file name, as Dune likes to do, which I just renamed to something much shorter after asking a few questions here:
What I have NOT done yet...
I have not loaded any files onto the new drives yet, but will likely do so tonite. This means I have not verified clean BD ISO playback from these drives and have not seen the speed of them in use.
I keep my player in another room so I have no idea (or care) how loud the Icy Dock is, but there is some fan noise from the included fan for sure. This may matter a great deal for those using it in the same room and you may want to upgrade to a much better fan.
I will follow up with performance while in use, and I am going to consider doing a reformat on my PC so that they can be in NTFS format instead of EXT2 so if I stop using the Dune and want to keep using the drives I can just run hang them off a new player that uses NTFS easily as this is more of a industry standard.
