Frequently Asked Questions (FAQ)
Q1: Why should I choose an SSD over a traditional HDD for my Mac?
A1: SSDs offer significantly faster speeds, greater durability (no moving parts, so less prone to damage from drops), and are generally more compact and lightweight. For Mac users, this translates to quicker file transfers, faster application loading, and a more responsive system overall.
Q2: What’s the best capacity for an external SSD for Mac?
A2: The “best” capacity really depends on your needs. While you might initially be searching for a 250GB SSD, many users find 500GB, 1TB, or even 2TB offers better value and more headroom for future storage needs. For basic backups or a boot drive, 250GB (like the SSK reviewed) can be sufficient, but for media files or large project work, 1TB or 2TB is often recommended.
Q3: Do I need to format an external SSD for my Mac?
A3: Most external SSDs come pre-formatted for Windows (NTFS). While your Mac can read NTFS drives, it can’t write to them without third-party software. For optimal performance and full read/write access on your Mac, it’s best to format the SSD to APFS (Apple File System) or exFAT if you need cross-platform compatibility with Windows.
Q4: What’s the difference between USB 3.2 Gen1, Gen2, and Gen 2×2?
A4: These refer to the USB transfer speeds.
– USB 3.2 Gen 1 (formerly USB 3.0/3.1 Gen 1): Up to 5Gbps (around 500MB/s).
– USB 3.2 Gen 2 (formerly USB 3.1 Gen 2): Up to 10Gbps (around 1000MB/s). This is what most modern external SSDs use.
– USB 3.2 Gen 2×2: Up to 20Gbps (around 2000MB/s). This is the fastest current widely available standard for external drives, seen in products like the Crucial X10. Ensure your Mac supports the corresponding USB standard for maximum performance.
Q5: Are these external SSDs compatible with older Mac models?
A5: Yes, most modern external SSDs (including those reviewed here) come with both USB-C and USB-A cables or are compatible with adapters, ensuring broad compatibility with older Macs that might only have USB-A ports, as well as newer Macs with USB-C/Thunderbolt 3/4 ports. Performance might be limited by the older port’s speed.
Q6: What is APFS optimization, and why is it important for Mac users?
A6: APFS (Apple File System) is Apple’s proprietary file system designed for SSDs. When an external SSD is “APFS optimized,” it means it’s pre-configured to work seamlessly and efficiently with macOS, potentially offering better performance and integration for Mac-specific features. The Crucial X9 Pro for Mac is a great example of this.
Q7: Is password protection necessary for my external SSD?
A7: For sensitive data, password protection is highly recommended. It adds an extra layer of security, ensuring that even if your drive is lost or stolen, your information remains private. Features like 256-bit AES hardware encryption (found in the SanDisk Extreme) offer robust protection.

Choosing the right external SSD for your Mac can significantly improve your digital life, whether you’re a student, a professional, or just someone who needs more space. While your initial search might be for a Crucial best 250gb ssd external hard drive for Mac, consider the value and features offered by slightly larger capacities.
