Goodbye Photos.app

So after living with the new Photos.app for two week now, I’m astounded by how much disk space it’s using for previews, thumbnails, and caches.

To recap, I have a library of roughly 9200 photos that I store on a second drive, since my OS drive is an SSD. These are mostly RAW files (e.g. NEF, RW2, etc.) The initial import to Photos.app created a library of 12.18GB. This is just previews and thumbnails.

I have not added or edited a single photo inside Photos.app since the initial import; I’ve only used it as a browser.

And the photos library has now grown to 16.68GB, plus it’s keeping a separate/secondary cache over 8GB inside the app sandbox storage. (e.g. ~/Library/containers/com.apple.photos)

This is just absurd.

For comparison, I just updated to lightroom 6, and generated smart previews for my entire library.

The catalog itself (e.g. lrcat file) is 85MB
The Smart Previews lrdat file is 9.11GB
The main Previews lrdat file is 3.66GB
And the cache folder? 2.8MB

So Photos.app, with no edits whatsoever, is using around 25GB of disk space.
Lightroom 6, with quite a lot of edits; flagged files, tags, collections, etc. is using 12.5GB; half as much space as Photos.app

At this point, until Apple reigns in the disk-space bloat with Photos, I’m swapping my lightroom library back onto my SSD, and moving the Photos.app library to the slower HDD; the app just isn’t worth losing 12.5GB of space on my SSD compared to lightroom and all that it offers.
