Choosing an external storage device is a decision driven by technical requirements and your specific use case. External Solid-State Drives (SSDs) have established themselves as the standard for both professional and personal use, outperforming traditional hard disk drives (HDDs) with significantly higher transfer speeds, a more robust design with no moving parts, and a more compact form factor. This article breaks down the key criteria for selecting an external SSD and presents a curated selection of models for various use cases.
The performance and suitability of a portable SSD depend on several technical parameters. An informed decision requires weighing these factors against your personal needs.
Speed is often the primary decision-making factor. It is determined by the internal SSD technology (e.g., PCIe NVMe) and the external interface.
Most modern SSDs use a USB-C SSD connector, which is the physical port used for all the USB and Thunderbolt standards mentioned above.
The capacity you need depends directly on the type and volume of data you plan to store.
For mobile use, physical resilience is a key factor. A rugged external SSD is characterised by the following features:
An external SSD should work seamlessly with your existing devices. Most models are compatible with Windows, macOS, and Linux. For specific use cases, such as using it as an external SSD for Mac or an external SSD for PS5, you should check for compatibility with the respective file systems (APFS, exFAT). Hardware encryption (e.g., AES 256-bit) also provides enhanced protection for sensitive data against unauthorised access.
Based on the technical criteria above, we have compiled a selection of external SSDs for different user profiles.
Why we recommend it: The Samsung T7 represents a well-balanced combination of speed, security, and compact design. It uses the common USB 3.2 Gen 2 interface, ensuring broad compatibility while delivering high performance for everyday and professional tasks.
Pros:
Who it's for: Users looking for a reliable and fast all-round solution for backups, transferring data between PC and Mac, or expanding storage for laptops and consoles.
Why we recommend it: The T7 Shield builds on the T7's concept by adding significantly enhanced durability. With its IP65 certification and high shock resistance, it is designed for use in demanding conditions without compromising on speed.
Pros:
Who it's for: Photographers, videographers, and content creators who frequently work outdoors or while travelling. Also for users who need an exceptionally durable storage solution for external SSD video recording or for backups in rugged environments.
Why we recommend it: The Lexar ES5 is aimed at users who require maximum transfer speeds and utilise modern recording workflows. Its support for USB 3.2 Gen 2x2 and MagSafe compatibility make it a specialised tool for direct video recording with the latest smartphones.
Pros:
Who it's for: Professional content creators and tech-savvy users who record directly from their smartphone (e.g., iPhone 15/16 Pro, Galaxy S25) in the highest quality. Also for users with a PC or laptop equipped with a USB 3.2 Gen 2x2 port to take full advantage of its maximum speed.

1. What is the difference between an external SSD and an external HDD? The main difference lies in the technology. An SSD (Solid-State Drive) uses flash memory with no moving parts, making it faster, quieter, and more shock-resistant. An HDD (Hard Disk Drive) stores data on rotating magnetic platters read by a read/write head. HDDs are typically slower, more sensitive to impacts, and often offer more storage space for a lower price.
2. Can I use an external SSD for my PS5 or Xbox Series X/S? Yes, external SSDs are excellent for expanding the storage of modern consoles. You can play PS4 games directly from an external SSD for PS5. PS5 games can be archived on the external SSD to free up internal space but must be moved back to the internal SSD to be played. Similar conditions apply to the Xbox Series X/S. A fast USB 3.2 Gen 2 SSD will significantly reduce loading and transfer times.
3. Do I need special software to use an external SSD? For basic data storage, no additional software is usually required. Most external SSDs come pre-formatted (typically with exFAT) and are instantly recognised by Windows and macOS. For advanced features like enabling hardware encryption or performing firmware updates, manufacturers like Samsung provide optional management software (e.g., Samsung Magician).
