5 Things to Know About the iMac 24-Inch (M1) Storage
The SSD is soldered to the logic board You cannot upgrade or replace the storage after purchase. Choose your capacity carefully when ordering.
256GB is the base option This is fine for basic tasks like web browsing and email, but you will run out of space quickly with photos, videos, or large apps.
512GB is the practical minimum Most users should start here. It gives enough room for the operating system, common applications, and a reasonable media library.
1TB or 2TB are for heavy users Only pay for these if you work with large files, run multiple virtual machines, or keep extensive local media collections.
External storage is your only upgrade path Use Thunderbolt or USB-C drives for extra space. They are slower than the internal SSD but far cheaper than buying a higher-capacity iMac upfront.
