Hello, I am currently thinking about purchasing a 16TB Quad-Bay External HDD, yet I hear only about 10.7TB of that space is actually usable storage. I don't know if this changes from each manufacturer, but the device itself is the Buffalo Drivestation Quad. I currently have an 8TB HDD from Buffalo, but month by month it seems I am fast approaching its limits so I was interested in making the leap and going for a large upgrade this time around to quell my storage needs for good. I run in RAID 0 by the way, and I'd love it if someone could answer how much usable storage is available with that Buffalo 16TB drive. Thanks.
