Buyers Guide to External SSDs: Performance and Security

Managing large amounts of data has become an everyday necessity for many. Whether it's high-resolution photos, 4K video projects, extensive game libraries, or simply crucial backups, the need for fast, reliable, and portable storage is constantly growing. An external SSD (Solid-State Drive) offers a high-performance solution that far surpasses traditional hard disk drives (HDDs) in speed and durability.

This guide is here to help. It highlights the most important technical features and presents a selection of models to provide you with a solid basis for making an informed decision based on your specific needs.

What to Look for When Buying an External SSD

Choosing the right model depends on several technical factors. The following three criteria are crucial for most use cases.

1. Speed and Interface: The Decisive Factor

Transfer speed is often the main selling point for an SSD. This is largely determined by the built-in technology and the interface.

• USB 3.2 Gen 2 (10 Gbps): This is the common standard for a fast external drive, enabling theoretical speeds of up to 1,050 MB/s. It's sufficient for most tasks, including 4K video editing and quick backups.
• USB 3.2 Gen 2x2 (20 Gbps): This interface doubles the bandwidth and can reach speeds of up to 2,000 MB/s. To unlock this potential, the port on your computer (PC or laptop) must also support this standard.
• Connector Type: Modern external SSDs almost exclusively use the USB-C connector. It's reversible and widely adopted. Many models come with adapters or extra cables for older USB-A ports.

2. Capacity: How Much Storage Space Do You Need?

The storage capacity you need depends directly on your usage habits.

• 1 TB - 2 TB: An external 2TB SSD is a great choice for general use. It offers enough space for operating system backups, a moderate photo collection, documents, and installing a few games.
• 4 TB and More: For professional users like videographers or 3D artists, an external 4TB SSD or larger is often the better choice. Large project files and high-resolution video footage quickly fill up smaller drives. An SSD for video editing should therefore be generously sized.

3. Durability and Compatibility

If you frequently transport your data, physical durability and compatibility with various devices are important.

• Durability: A rugged external SSD is characterized by features like drop protection and an IP rating. For example, an IP65 rating means the device is dust-tight and protected against water jets.
• Compatibility: Check if the SSD is compatible with your operating systems. Most drives work seamlessly with Windows and macOS. For use with mobile devices like the iPhone 15 Pro, direct compatibility is crucial, especially for features like external ProRes video recording. An external SSD for Mac is usually formatted appropriately out of the box or can be easily reformatted.

Samsung T7 Shield Portable SSD 4TB

Why It Stands Out: The Samsung T7 Shield combines a high 4TB storage capacity with exceptional durability. Its rubberized exterior not only provides a secure grip but also effectively protects the SSD from the elements and drops.

Advantages:

• High durability with an IP65 rating for water and dust resistance.
• Drop protection from a height of up to 3 meters (according to the manufacturer, onto a steel floor).
• Large storage capacity of 4 TB for extensive data archives.
• Sequential read/write speeds of up to 1,050/1,000 MB/s via USB 3.2 Gen 2.
• Optional AES 256-bit hardware encryption to protect sensitive data.

Who Is It For? This model is ideal for photographers, video producers, and anyone who needs a reliable and rugged external SSD for use in demanding outdoor or travel conditions.

Lexar ES5 Portable SSD 2TB

Why It Stands Out: The Lexar ES5 is designed for maximum speed and mobile workflows. With its USB 3.2 Gen 2x2 interface, it achieves extremely high transfer rates. A special feature is its MagSafe compatibility, allowing for easy attachment to an iPhone 15 Pro for direct video recording.

Advantages:

• Very high read and write speeds of up to 2,000 MB/s (requires a compatible USB 3.2 Gen 2x2 port on the host device).
• Supports direct recording of Apple ProRes 4K videos.
• IP65-certified and drop-proof from up to 3 meters.
• Slim design with practical cable management.

Who Is It For? The Lexar ES5 is aimed at content creators who film directly with their smartphone and can benefit from the MagSafe functionality. It is also an interesting option for power users whose computers have a USB 3.2 Gen 2x2 port and who require maximum transfer performance.

Samsung Portable SSD T7 2TB

Why It Stands Out: The Samsung T7 is an established and versatile model that offers a balanced combination of speed, compactness, and security. Its slim aluminum casing makes it an elegant yet durable companion for everyday use.

Advantages:

• Compact and lightweight design (58 grams) in a sturdy aluminum housing.
• Reliable read/write speeds of up to 1,050/1,000 MB/s.
• Integrated AES 256-bit hardware encryption for high data security.
• Broad compatibility with PC, Mac, gaming consoles, and mobile devices.

Who Is It For? The Samsung T7 is an excellent all-round solution for students, office workers, and home users looking for a fast, portable, and secure external 2TB SSD for daily backups, data transport, and storage expansion.

Frequently Asked Questions

What is the difference between an external SSD and an HDD?

An external SSD (Solid-State Drive) uses flash memory with no moving parts. This makes it significantly faster, quieter, more energy-efficient, and more resistant to shocks than a traditional external HDD (Hard Disk Drive), which stores data on rotating magnetic platters. HDDs typically offer more storage space for less money but are inferior in performance and durability.

Which external SSD is suitable for video editing?

An SSD for video editing should primarily offer high and consistent read/write speeds of at least 1,000 MB/s to ensure a smooth, stutter-free workflow. High capacity is also important, which is why models with 2TB are the minimum, and 4TB or more is recommended. A reliable interface like USB 3.2 Gen 2 or Thunderbolt is also crucial.

Can I use an external SSD with my iPhone 15 Pro?

Yes, thanks to their USB-C port, the iPhone 15 Pro and Pro Max support direct recording of high-resolution ProRes videos to a compatible external SSD. This is particularly useful as ProRes files are very large and can quickly fill up internal storage. Models like the Lexar ES5 or the Samsung T7 are suitable for this use case. It is advisable to check for compatibility with the respective SSD manufacturer.
