Can 2025 iMac storage be expanded?

Looking to purchase a new iMac to replace our 2012 27” iMac, but need more then 2tb storage which is the largest Apple offer now. Can this be expanded aftermarket?

iMac 27″, macOS 10.15

Not internally. You can always add external drives (preferably SSDs) to whatever extent you need.


In the current Mac lineup, here are the internal storage capacities available today, depending on model & config:


24" iMac - 512GB, 1TB, 2TB

mac Mini - 512GB, 1TB, 2TB, 4TB, 8TB

mac Studio - 512GB, 1TB, 2TB, 4TB, 8TB

mac Pro - 1TB, 2TB, 4TB, 8TB


Those are the choices.

In my opinion 1TB is the sweet spot between cost & capacity. For additional storage I have external USB 3.2 Gen2x1 (10Gbps) SSD drives connected to my iMac, one each for Photos & Audio and two for Video. Their performance is fantastic and it's hard to tell any difference from the internal SSD. With a new (current) Mac you could use Thunderbolt 4 or 5, depending on the model, for even more speed.
