512GB SSD is just the base model. If you need to store lots of things locally, you would option up to the larger storage. The nice thing about a desk top is you can expand with external storage easily and more cheaply.I strongly disagree. While 16gb of ram is fine for most photographers, 512gb of SSD is simply not enough workable space. I'm a full time professional photographer and even 2TB of SSD space is not enough. 4TB or 8TB is a solid amount of workable space for multiple weddings, events and various photo shoots, not to mention all the 1:1 previews Lightroom generates. 512gb would be an incredible struggle.
