I am considering buying a new Mac, but the largest hard drive I can get is 3TB. My plan will be to buy an external hard drive for images only. I've heard that lightroom may not work because it wasnt designed to reference images on external hard drives. This doesnt make sense to me but wanted to confirm before making my hardware purchase.
Putting your photos on an external drive is fine. I have 100k plus on an 8TB Thunderbolt drive and it works without any issues.
Thank you Ian! Sorry for long delay to thank you.
