I got this a while ago and it's been performing fantastically, Lexar Professional Workflow 6TB SSD over thunderbolt, each drive is removable and has a little case, I also have off shot an SD/CF/MicroSD/USB3 bays in a separate enclosure. my work flow for it is I keep a month of photos on each drive and then remove it if I need to edit on the road and put it back into the slot when done, catalog is synced via iCloud and is persistent across my 4 Macs.
That's an interesting idea.
A few questions:
Do the card readers copy to the SSDs automatically with the computer? If so how does it select the SSD to use?
How do the drives show up on the computer? Is one big volume or a drive for each SSD?
Do you back this up in any way or just rely on iCloud?
I've been looking at a NAS for all my photos and work with Lightroom, but as I don't really share between machines much, this might be a better, and faster, option.
A little pricey from what I can see though!
