Thanks for the replies.
For the last couple of years I've been using
these for backup. I've had no problems so far.
I'm not a high-volume shooter so, at the end of each year, in addition to the LaCie, I copy all RAW files onto external SSDs via USB. Thereby, worst case scenario, I have to re-save the TIFFs and (where necessary) do any Photoshop that is required. So far, I've never had to do this.
I like the idea of giving Photoshop (and maybe C1 too) its own SSD scratch-disk. That said, this computer will be used for nothing except digital editing, so Photoshop would be sharing the existing one SSD with Windows 10 Pro, C1 and very little else.
One of the spinning drives would be exclusively for RAW files and one for Edited files - this mirrors exactly what I currently have, along with all software on an SSD.
No intention to overclock.
I've made changes to the spec - Optical Drive, PSU, RAM - which can be seen
here.1. Any views on my choice of case?
2. I presume that I could add a Photoshop SSD disk later, if I change my mind?
Thanks.
