External SSD Buying Guide: How to Avoid a Bad Purchase

An external SSD seems like a simple purchase: you find one with enough storage and a reasonable price. However, the market is filled with marketing traps that lead to disappointment. You might buy a drive that's much slower in practice than advertised, or a model that becomes unusable after a minor drop. This guide will help you make the right choices based on factual specifications, ensuring you invest in a product that actually speeds up your workflow and keeps your data safe.

The 2 Most Common Traps When Buying an External SSD

Before we look at specifications, it's crucial to recognise the marketing tricks that often lead to a bad purchase.

1. The "Up To" Speed Trap: Manufacturers advertise impressive speeds like "up to 2,000 MB/s." What they often fail to mention clearly is that you can only achieve this speed if your computer or laptop has a specific, and often still rare, USB 3.2 Gen 2x2 port. On a standard port, that same SSD could be up to four times slower.
2. The Illusion of Ruggedness: A compact size is convenient, but it says nothing about durability. Many cheaper models have a fragile plastic casing that offers little protection. For professionals who are often on the move, like photographers or videographers, a rugged external SSD is not a luxury but a necessity. Without clear specifications on drop protection or water resistance, a "sturdy" appearance is merely a marketing claim.

Core Parameters: What to Look For

To bypass the traps, focus on three verifiable specifications. These determine the actual performance and reliability of a portable SSD.

1. Speed and the USB Standard: What Does It Really Mean?

An SSD's speed is entirely dependent on the combination of the drive and your device's USB port. These are the most common standards:

• USB 3.2 Gen 1 (5 Gbps): Delivers real-world speeds of up to approximately 500 MB/s. Fine for general backups and transferring documents.
• USB 3.2 Gen 2 (10 Gbps): The current standard for most modern laptops and PCs. Provides speeds up to approximately 1,050 MB/s. Ideal for quickly transferring large photo libraries and light video editing. A high-speed external SSD like the Samsung T7 is a prime example.
• USB 3.2 Gen 2x2 (20 Gbps): The fastest option, with speeds up to 2,000 MB/s. Requires a compatible port on your host device. Perfect for professionals working with 4K or 8K video files. The Samsung T9 is designed to leverage this speed.

Therefore, always check which USB port your computer has before you buy an external SSD. Most SSDs use a USB-C SSD connection, but the underlying standard determines the speed.

2. Storage Capacity: How Much Do You Need?

The required capacity depends on your usage.

• 1 TB: A popular choice for most users. A 1TB external SSD offers enough space for thousands of photos, important documents, software backups, and a modest game library.
• 2 TB - 4 TB: Essential for content creators who work with large video files, or for gamers who want to expand their SSD for PS5 or PC without constantly deleting games.

3. Durability and Compatibility

Look for objective specifications for durability:

• Drop Protection: Indicated in meters (e.g., "drop-resistant up to 3 meters"). This gives an idea of how well the internal components are protected.
• IP Certification: An IP rating like IP65 means the drive is dust-tight and protected against water jets. This is a key factor for those who often work outdoors or in demanding environments.
• Compatibility: Most SSDs work out of the box with Windows and macOS. For use with an external SSD for Mac or a game console, you may need to reformat the drive.

Frequently Asked Questions

Can I use any external SSD for my PS5?

Yes, you can use an external SSD to expand your PlayStation 5's storage. You can play PS4 games directly from it and archive PS5 games to free up space on the internal drive. To play a PS5 game, however, you must first move it back to the internal storage. The SSD must support at least the USB 3.2 Gen 1 standard. Models like the Samsung T7 and T7 Shield are popular choices for this purpose.

What is the advantage of an external SSD compared to a cheaper USB stick?

The main difference is performance. A portable SSD is built with the same technology as the internal SSD in your computer, making it many times faster, especially when writing (large) files. This makes an SSD suitable for tasks like video editing directly from the drive or running software. A USB stick is primarily intended for easily transferring smaller files and is significantly slower for that purpose.

My new, high-speed external SSD is slow. How is that possible?

This is almost always due to your computer's USB port or the cable being used. A high-speed external SSD like the Samsung T9, which promises 2,000 MB/s, will only reach this speed when connected to a USB 3.2 Gen 2x2 port. If you connect it to an older or slower port (like Gen 2 or Gen 1), the speed will be limited by what the port can handle. Therefore, always check the specifications of both the SSD and your computer, and use the cable that came with the drive.
