Frequently Asked Questions (FAQs)
Q1: What is the main difference between an external SSD and a traditional external HDD for Mac?
A1: The primary difference is speed and durability. SSDs (Solid State Drives) use flash memory and have no moving parts, making them significantly faster (often 5-10x) and more resistant to drops and shocks than HDDs (Hard Disk Drives), which use spinning platters. SSDs are also typically smaller and lighter.
Q2: Do I need a special external SSD for my Mac, or will any external SSD work?
A2: Most modern external SSDs are universally compatible with Macs. The main thing to look for is the connection type (usually USB-C), which is prevalent on newer Macs. The drives reviewed here are all “plug-and-play” with macOS.
Q3: What does “NVMe” mean, and why is it important for an external SSD?
A3: NVMe (Non-Volatile Memory Express) is a communication protocol designed specifically for SSDs. It allows for much faster data transfer speeds compared to older protocols like SATA. For an external SSD, NVMe technology ensures you’re getting the fastest possible performance over a USB-C connection, crucial for demanding tasks.
Q4: Is hardware encryption really necessary for an external SSD?
A4: While not strictly “necessary” for everyone, hardware encryption offers a robust layer of security for sensitive data. If your external SSD contains personal information, client files, or any data you wouldn’t want falling into the wrong hands, hardware encryption (like 256-bit AES) is highly recommended for peace of mind.
Q5: What’s the difference between USB 3.2 Gen 2 and other USB standards?
A5: USB 3.2 Gen 2 (often called USB 3.1 Gen 2) offers data transfer speeds up to 10 Gigabits per second (Gbps), which translates to around 1250MB/s. This is significantly faster than older standards like USB 3.0 (5Gbps) or USB 2.0 (480Mbps), allowing modern NVMe SSDs to reach their potential speeds. Many newer Macs feature Thunderbolt ports, which are backward compatible with USB-C and offer even higher potential speeds.
Q6: Can I use an external SSD to boot my Mac or run applications?
A6: Yes, you absolutely can! Many Mac users choose to install macOS or specific applications on a fast external SSD to improve performance, especially if their internal drive is older or slower. For professionals, running demanding applications or editing video directly from an external SSD can significantly speed up their workflow.
Q7: How do I format an external SSD for my Mac?
A7: When you connect a new external SSD to your Mac, you’ll likely want to format it using Disk Utility. For optimal performance and compatibility with macOS, choose “APFS” (Apple File System) as the format. If you need to share the drive with Windows computers, “ExFAT” is a good cross-platform option, though it might not offer the same performance or features as APFS on Mac.
