Ranked #4 in Best External SSDs

Crucial X10 Pro

4.0

6 sources1 derived$185.52as of Aug 1

The SSD Review and StorageReview both frame the Crucial X10 Pro as a high-performance portable drive for media professionals, moving data over USB 3.2 Gen 2x2. They praise the ultra-compact aluminum build and the security package, hardware encryption plus a 5-year warranty, that separates it from the base X10. Some testers saw sustained write performance dip below Crucial's maximum claims under heavy loads. Get it if you have a compatible 20Gbps port and value speed and durability over cost; on older USB ports the slower, cheaper X9 Pro makes more sense.

Strengths

— Supports USB 3.2 Gen 2x2 interface for up to 20Gbps transfer speeds
— Compact 65 x 50mm unibody anodized aluminum chassis weighing 1.48 ounces
— Includes 256-bit AES hardware encryption with software-based password protection

Watch-outs

— Real-world sustained write speeds may fall short of the advertised 2,000MB/s peak
— Higher price point compared to standard USB 3.2 Gen 2 portable SSDs

Ranked #5 in Best External SSDs

OWC Envoy Ultra

4.0

3 sources1 derived$699.99as of Aug 1

OWC bills the Envoy Ultra as the world's first Thunderbolt 5 bus-powered 8TB drive, pairing rugged durability with high-speed storage aimed at creative professionals. Coverage focuses on the hardware's compact size and speed, and on the wider OWC Thunderbolt 5 ecosystem (Stack AI), which runs AI models locally on existing PCs and laptops. Full AI acceleration on Mac is planned for a future release rather than shipping now. Windows and Linux power users and video creators who need massive portable storage are the fit; Mac AI enthusiasts will be waiting on software updates.

Strengths

— World's first Thunderbolt 5 bus-powered 8TB drive in its class
— Rugged, blazing fast SSD design
— Compact form factor suitable for professional workflows

Watch-outs

— Full speed is limited to Thunderbolt 5 hosts; Thunderbolt 4 and USB4 cap it at 40 Gbps
— Mac support for AI acceleration features is planned for future release
