I don't under that stuff Merc mentioned. If it is set up on one computer, can the SSDs be moved to a completely different one and the data on the "array" of three drives still be accessed?
Here's an example:
I have four top level "Pictures" folders.
Pictures\
Photos
Inputs
Internet
Outputs
Photos are personal images that I've downloaded or saved from elsewhere.
Inputs are where SDcards go when they're imported, plus temp folders for TIFFs and other working space.
Internet is just random crap I've saved from the web or something.
Outputs are where things go after they've been processed from Inputs.
Photos and Internet actually live on D:\data\Pictures. And that's fine and good and normal. You can just relocate that folder in Windows in the normal way.
Inputs and Outputs live on their own storage volumes, which I create like this:
mklink -d d:\data\Pictures\Inputs \\?\Volume{some-windows-guid}\Inputs
... using the GUID because I'm too lazy to assign some of my storage its own drive letter.
What this means, from a functional standpoint, is that Outputs sits on a 2TB drive of its own, and Inputs sits on a 4TB RAID0, and both are presented to my desktop as part of the regular Pictures Library, along with the "Pictures" Data folder that sits on my NAS.
There's a process that ensures that anything that's on Outputs gets mirrored on my NAS. The assumption I make about Inputs is that they can be regenerated from the original SD card if I care that much, but I do mirror a potion of it, the "picks" that get imported for editing, as well as the actual Capture One libraries I use, which have their own, separate directory structure.
How does all this work with Libraries?
When I open Pictures, I see the massive list of personal photos that live on my NAS, the personal photos I've saved relatively recently and all the stuff that lives on those two independent volumes (disks). For the most part, between volumes and Libraries, I don't have to think about where my data actually is. I either want to see it all in one place, or I can treat it like it's all the same thing. That's why those things working together are so useful.
