Change Hard Drive on Your iMac: A Comprehensive Guide
Upgrading the hard drive in your iMac can significantly enhance its performance and storage capacity. Whether you’re looking to replace a failing drive or simply want more space, this guide will walk you through the process step by step.
Understanding Your iMac’s Hard Drive
Your iMac’s hard drive is an essential component that determines how quickly your computer boots up and how much data you can store. Before you begin the upgrade process, it’s important to understand the type of hard drive your iMac has.
| Model | Hard Drive Type | Storage Capacity |
|---|---|---|
| 21.5-inch iMac (Mid 2011 to Early 2015) | 5400 RPM SATA | 500GB to 3TB |
| 27-inch iMac (Mid 2011 to Early 2015) | 5400 RPM SATA | 1TB to 3TB |
| 21.5-inch iMac (Late 2015 to Early 2017) | 5400 RPM SATA | 1TB to 2TB |
| 27-inch iMac (Late 2015 to Early 2017) | 5400 RPM SATA | 2TB to 4TB |
| 21.5-inch iMac (Mid 2017 to Early 2019) | 5400 RPM SATA | 1TB to 2TB |
| 27-inch iMac (Mid 2017 to Early 2019) | 5400 RPM SATA | 2TB to 4TB |
Once you know the type of hard drive your iMac has, you can proceed to purchase a compatible replacement drive.
Choosing the Right Replacement Hard Drive
When selecting a replacement hard drive, consider the following factors:
- Capacity: Choose a drive with a larger capacity if you need more storage space.
- Speed: A solid-state drive (SSD) offers faster performance than a traditional hard disk drive (HDD). However, SSDs are more expensive and have a smaller capacity.
- Interface: Ensure the replacement drive has the same interface as your iMac’s original drive (e.g., SATA 3 or SATA 2).
Popular options for iMac hard drive upgrades include the following:
- OWC Mercury Elite Pro Mini: This is a high-performance 2.5-inch SATA SSD that offers up to 2TB of storage.
- Seagate Barracuda: This is a 2.5-inch SATA HDD with capacities ranging from 1TB to 4TB.
Preparation and Tools
Before you begin the upgrade process, gather the following tools and materials:
- Replacement hard drive: Ensure it’s compatible with your iMac model.
- Screwdriver set: A small Phillips-head screwdriver is typically required to remove the iMac’s back panel.
- Anti-static wrist strap: This helps prevent static electricity from damaging your iMac’s internal components.
- Soft cloth: Use this to clean the iMac’s interior and exterior.

Follow these steps to upgrade your iMac’s hard drive:
- Power off your iMac and disconnect all cables.
