This comprehensive guide compares the fastest external SSDs and hard drives for gamers, creators, and professionals, featuring models with USB 3.2, Thunderbolt 4, and Thunderbolt 5 connectivity across multiple price points and storage capacities.
In 2025, the landscape of external storage has shifted dramatically. Gone are the days when external drives were merely slow backup vaults. Today, portable SSDs function as active workspaces, allowing gamers to run AAA titles directly from the drive and content creators to edit 8K raw footage without dropping a frame.
The arrival of Thunderbolt 5 has shattered previous speed ceilings, offering bandwidths that rival internal NVMe drives. However, with the coexistence of USB 3.2 Gen 2x2, USB4, and Thunderbolt standards, choosing the right drive can be confusing. This guide cuts through the technical jargon to present the absolute best portable SSDs available this year, focusing on real-world performance for gaming, professional workflow, and travel.
Before diving into the recommendations, it is crucial to match the drive to your device:
If you are a professional chasing the absolute pinnacle of performance in 2025, the OWC Envoy Ultra is the drive to beat. It is one of the first commercially available external SSDs to harness the power of Thunderbolt 5, delivering throughput that was previously unimaginable in a portable form factor.
In real-world testing, this drive is capable of jaw-dropping performance, reaching speeds over 6,000 MB/s. For videographers transferring terabytes of daily rushes, this speed difference changes the workflow from hours to minutes. Even during sustained write sessions, it maintains impressive stability.
However, this performance comes with a caveat: you need a Thunderbolt 5 equipped machine, such as the latest Macs with M4 Pro/Max chips, to unlock its full potential. It is backward compatible with Thunderbolt 4 and USB4, but you would be paying a premium for speed you cannot use on older hardware.

The Corsair EX400U is a standout release for 2025, perfectly bridging the gap between gaming utility and creative workflow. Leveraging the USB4 interface, it delivers blistering read speeds of up to 4,000 MB/s and write speeds of 3,600 MB/s. This makes it significantly faster than the previous generation of 20Gbps drives while remaining reasonably priced.
What sets the EX400U apart is its thoughtful design. It is incredibly small and features a magnetic back, allowing it to snap onto the back of modern iPhones and some Android devices. This is a game-changer for mobile content creators recording high-resolution ProRes video directly to external storage. For gamers, the high bandwidth supports fast load times for modern titles, making it an excellent library expansion for laptops and handheld gaming PCs.

Samsung has long been a dominant force in portable storage, and the T9 continues that legacy. While it utilizes the USB 3.2 Gen 2x2 interface rather than USB4, it remains the "Goldilocks" drive for most users—fast enough for 4K editing, widely compatible, and built like a tank.
The T9 offers sustained read and write speeds hovering between 1,700 MB/s and 2,000 MB/s. Its unique selling point is its physical design; the rubberized, textured coating provides excellent grip and shock absorption, capable of withstanding drops from up to three meters. It feels premium in the hand, similar to a high-end wallet.
Creators should note that Apple computers generally do not support the Gen 2x2 standard (limiting this drive to 1,000 MB/s on Macs), making the T9 a better choice for Windows PC users and editors who need reliable, high-capacity storage up to 4TB.
For outdoor photographers and travel vloggers, the SanDisk Extreme PRO has been the default choice for years. The latest iteration adopts USB4 connectivity, finally bringing its speed in line with its rugged reputation. Capable of speeds up to 3,800 MB/s when paired with a compatible system, it ensures that backing up footage in the field is instantaneous.
The drive retains its iconic carabiner loop design and robust IP55 water and dust resistance, making it ideal for clipping onto a camera bag during a hike. While it commands a premium price, the combination of extreme durability and top-tier transfer speeds makes it the best external SSD for professionals who work in harsh environments.

If you need high speed and extreme durability without breaking the bank, the Adata SD810 is the hidden gem of 2025. It meets the strict IEC IP68 standard, meaning it is dust-tight and can survive submersion in water for up to 60 minutes. This makes it even more rugged than many of its more expensive competitors.
Performance-wise, it punches above its weight class with USB 3.2 Gen 2x2 speeds reaching 2,000 MB/s. User testing has shown it maintains peak transfer speeds remarkably well during long file transfers, avoiding the aggressive thermal throttling seen in cheaper drives. It is compact, lightweight, and works instantly with gaming consoles like the Xbox, offering a fantastic price-to-performance ratio.
When selecting a portable SSD this year, keep the following criteria in mind:
Whether you are editing 8K video on a flight or storing a massive Steam library, the options above represent the best technology 2025 has to offer.
