Storage info for each iMac — details on speed, dimensions, and hard drive and SSD interface specifics — is listed below along with common identifiers suitable to identify a iMac in order to determine which hard drives and SSDs are compatible.

If you are not sure which iMac you have, and the Model Identifier and EMC Number below are not sufficient for identification, you also may look it up with other identifiers -- including its Serial Number -- with EveryMac.com's Ultimate Mac Lookup feature. If you need more help, refer to Mac Identification.

Click the triangle to the left of a system to open "Quick Specs" -- the two most relevant identifiers for storage, standard hard drive and/or SSD details, storage dimensions and connector type(s), and links to buy compatible storage from site sponsors -- and click on the name or image for complete specifications. Asterisks indicate important details on the complete specs page.
