Advice on Mac mini setup for image processing

The Mac mini you asked about would be fine. Although (as a photographer myself) I'd suggest the 1TB SSD but I do understand you may be concerned about the relative cost of the internal SSD vs. an external SSD.

w/r/t a dock, you really don't need a dock unless you intend to attach more peripherals than the number of ports on the mini (3 TB4/USB4 + 2 USB 3.x). You can connect a good external HDD or SSD directly to the mini, either Thunderbolt 4, USB 4 or USB 3.x Gen 2.

Do note that SSD prices have skyrocketed this year and the cost may not be much different from the internal 1TB SSD option. If you do go with an external drive, for still images, a good 7200rpm HDD will be fine. Final note - regardless of what internal SSD you select, make sure you get a good external drive for backups!

I would say that the set up you have will work just fine, depending on what apps you are using for your image processing.

I personally have a M5 MacBook Air with 24GB RAM and 512GB SSD and it works quite well with the apps I use (ON1 PhotoRAW for initial DSLR processing and Affinity app (free) for prepping for web posting, printing, and for montages). I have my images on a fast very external USB4 drive (along with any application caches that I can put on it) for processing but I after that I archive on large HDDs (double backed up). Once you have done the processing there is no need to keep archives on expensive super fast drives.

However, if you can afford it, you may want to consider the Mini Pro. The additional CPU and especially GPU cores can speed up the processing considerably. If your photography is geared toward making money, the extra speed would be worth it.

Overall, it sounds fine for what you want to do, yes.

Make sure the dock is a good quality dock with a sufficiently fast connection i.e Thunderbolt so the included hard drive has enough bandwidth to move large files back and forth quickly.

Otherwise, you may want to consider a discrete external drive, as there have been issues with some docks randomly disconnecting the hard drive from he Mac which may cause corruption and data loss.

Are you planning on using Apple's Photos app for photo management or something else?

For Apple's Photos app, make sure the external drive is formatted as APFS or at least HFS+.

Are you planning on using Photoshop for processing?

If you are planning on moving the hard drive between Windows and Mac, do note macOS can't write to Windows NTFS formatted drives on its own. It can read from them however.

An HDD or SSD of 2 TB for your own external storage can be connected directly, with no need for a dock. Thunderbolt or USB4 for SSD, or some slower USB connection for an HDD.

The dock could be chosen to bring additional external connections, depending on your requirements. Preferably a Thunderbolt dock, as was mentioned.

SSDs are massively faster than HDDs, if you’re frequently accessing that storage.

Add some external storage of roughly 2.5x to 3x the aggregate capacity of whatever storage you want to protect, for Time Machine backups. HDD works fine here, unless you’re doing lots of restores.

If you have some typical apps that can be available, you can usually do a try-out at an Apple Store.

FWIW, I have a MacBookPro M4 Pro w/24GB RAM & 1TB SSD and use Photoshop, Lightroom, CaptureOne Pro, iMovie & Davinci Resolve on it and it performs beautifully.

• An M6 mini with 24GB RAM will do even better.
• The current mini Pro is an M5 Pro and is almost twice the price; I don't think it's worth it.

Thanks very much, really helpful.
