Frequently Asked Questions about External SSDs for Mac Thunderbolt 4
Q1: Why should I choose an external SSD with Thunderbolt 4 for my Mac?
A1: Thunderbolt 4 offers exceptional bandwidth (up to 40Gbps), allowing for incredibly fast data transfer speeds. This is crucial for tasks like 4K/8K video editing, running virtual machines, large file backups, or even playing games directly from the external drive without performance bottlenecks. While USB-C is compatible, Thunderbolt 4 provides superior speed and versatility.
Q2: What’s the difference between Thunderbolt 3, Thunderbolt 4, and USB4?
A2: All three use the same USB-C connector. Thunderbolt 3 (up to 40Gbps) was a proprietary Intel technology. Thunderbolt 4 (also up to 40Gbps) builds upon TB3 with guaranteed minimum speeds, improved security, and better compatibility with USB4. USB4 (also up to 40Gbps) is an open industry standard that incorporates Thunderbolt protocols. Essentially, Thunderbolt 4 is a super-set of USB4, meaning any Thunderbolt 4 device is compatible with USB4, and often with Thunderbolt 3. Your Mac’s Thunderbolt 4 port is backward compatible with all these standards.
Q3: Can I use a regular USB-C SSD with a Thunderbolt 4 port on my Mac?
A3: Absolutely! Thunderbolt 4 ports are fully backward compatible with USB-C devices. However, the USB-C SSD will only operate at its maximum USB speed (e.g., 5Gbps, 10Gbps, or 20Gbps for USB 3.2 Gen 2×2), not the full 40Gbps of Thunderbolt 4.
Q4: How much storage capacity do I need for my external SSD?
A4: This depends entirely on your usage. For general backups and document storage, 1TB or 2TB might suffice. If you’re a photographer, videographer, or work with large media files, 4TB or even higher capacities are recommended. Consider your current data needs and anticipate future growth.
Q5: Is an external SSD better than a traditional external HDD for Mac?
A5: Yes, in almost every way, except for raw cost per gigabyte. SSDs are significantly faster, more durable (no moving parts), lighter, and quieter than traditional HDDs. While HDDs still offer cheaper high capacities, SSDs provide a vastly superior user experience due to their speed.
Q6: How do I format an external SSD for my Mac?
A6: For optimal performance and compatibility with macOS, you should format your external SSD using Apple’s APFS (Apple File System) for macOS 10.13 High Sierra and newer, or HFS+ (Mac OS Extended) for older macOS versions. You can do this using Disk Utility, found in your Mac’s Utilities folder. Most drives come pre-formatted for general use, but reformatting for Mac ensures the best experience.
Q7: Will using an external SSD improve my Mac’s performance?
A7: While an external SSD won’t directly speed up your Mac’s internal operations, it can drastically improve workflows involving large files. If you’re editing video, running virtual machines, or storing your entire photo library on it, a fast external SSD can make those tasks feel much snappier compared to a slower drive, freeing up your internal storage for system files and applications.
Conclusion
Choosing the best external SSD for Mac Thunderbolt 4 is an investment in your productivity and workflow. While not every drive listed here is natively Thunderbolt 4 (many are USB 3.2 Gen 2×2 or Thunderbolt 3, which are fully compatible with your TB4 port and offer incredible speeds), they all represent top-tier options that maximize your Mac’s capabilities.
Whether you prioritize sheer, unadulterated speed, rugged durability for field work, or a perfect balance of performance and value, there’s an external SSD on this list that’s just right for your Mac. Ditch the slow external drives and embrace the lightning-fast future of external storage!
