My LR flies along. The last upgrade really improved speed. I have
1,396,852 photos stored on 3 Drobos. Most of the Drobo hard drives are
10TB Seagates but I also have some 4TB WD drives in there.
The only thing that seems slow is moving folders. I'm reorganizing and
when I move a folder that contains over 1000 photos within LR it sometimes
takes a full day. I can continue to work on other photos at the same time
so it's a minor nuisance.
I'm happy.
