Frequently Asked Questions
Q1: What is the best external SSD for Mac mini M4?
A1: The “best” external SSD for Mac mini M4 depends on your specific needs. For raw speed and a clean setup, a Thunderbolt-optimized ORICO Minimate (like the 40Gbps versions) is excellent. If you need extensive port expansion, a dock like the UGREEN or the Aluminum Stand with HDMI Hub offers versatility. For budget-conscious users, 10Gbps USB-C SSDs still offer fantastic performance.
Q2: Why do I need an external SSD for my Mac mini M4?
A2: While your Mac mini M4 is powerful, its internal storage might be limited, especially in base configurations. An external SSD provides fast, expandable storage for large files (videos, photos, projects), helps keep your internal drive free for macOS and apps, and can even be used for a bootable backup or a secondary operating system.
Q3: What’s the difference between an SSD enclosure and an external SSD?
A3: An external SSD is a complete, ready-to-use drive with the SSD built into a casing. An SSD enclosure is just the casing with the necessary ports; you buy the M.2 NVMe or SATA SSD separately and install it yourself. Enclosures offer more flexibility in choosing your SSD’s brand and capacity, often at a lower overall cost.
Q4: What speed should I look for in an external SSD for Mac mini M4?
A4: The Mac mini M4 features Thunderbolt 4 ports, which support speeds up to 40Gbps. To fully leverage this, look for “Thunderbolt SSDs” or “40Gbps NVMe enclosures.” If that’s overkill for your needs or budget, 10Gbps (USB 3.2 Gen 2) external SSDs are still very fast and widely available, offering speeds around 1000MB/s, which is excellent for most tasks.
Q5: Can I boot macOS from an external SSD?
A5: Yes, you can install and boot macOS from an external SSD connected to your Mac mini M4. This can be useful for running a different version of macOS, testing new software, or as a reliable backup. Ensure your external SSD is formatted correctly (APFS is recommended for macOS).
Q6: How do I format an external SSD for Mac?
A6: To format an external SSD for your Mac, connect it, open Disk Utility (Applications > Utilities), select the external SSD from the sidebar, click “Erase,” choose “APFS” as the format (or Mac OS Extended (Journaled) for older compatibility), and “GUID Partition Map” as the scheme. Give it a name and click “Erase.”
Q7: Are these external SSDs compatible with older Mac mini models?
A7: Many of these external SSDs and enclosures, especially those using USB-C (10Gbps) or Thunderbolt, are backward compatible with older Mac mini models (e.g., M1, M2, or Intel-based Macs) that have the corresponding ports. However, they might not achieve the absolute maximum speeds unless the older Mac also supports those specific transfer protocols. Always check the product’s compatibility list.
No matter your specific use case – whether you’re a video editor needing colossal, fast storage or just someone looking to archive their ever-growing photo collection – there’s a perfect external SSD for Mac mini M4 out there for you. Consider your speed requirements, desired capacity, and how much you value integrated hub functionality when making your choice. Happy computing!
