I've been looking at a Kanguru QSX external enclosure. I am hoping that it is works with a esata port multiplier using FIS based switching to expose the two raw disks. I have pair of 3tb drives that make up a ZFS backup pool and want a convenient way to attach and remove them. I know that Mediasonic and Sans Digital have 4 bay enclosures that will work, but for this price, I can live with a 2 bay array.
