I just copied 1005 random photos from a search to a folder on my ssd and the sort is absolutely instant. I moved the folder to the raid drive and the first sort displayed a green progress bar the first time for maybe 5 seconds (could have been just loading the thumbnails) but after that flicking between different sorts was instant.
I just copy all my photos to folders in a structure like Year/Month so they all load fast...
Ditto. The Canon software I use for the import does that for me by day and month then at the end of the year I dump the folders into a year folder.
The backup run loves it when I do that.
