OWC Envoy Ultra
Ranked #5 in Best External SSDs
OWC Envoy Ultra
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

Samsung T7 Shield
Higher ratedRanked #2 in Best External SSDs
Samsung T7 Shield
5 sources$435as of Aug 1

Reviewers rate the Samsung T7 Shield mainly on toughness: IP65 water and dust resistance plus 3-meter drop protection make it a reliable travel and outdoor drive. They also point to AES 256-bit hardware encryption and a 4TB capacity that is rare in Samsung's portable lineup. The soft silicone exterior attracts dust, and the top transfer speed of 1050MB/s only arrives if the host supports 10Gbps USB. Pick it when durability and security matter more than sleek looks or peak speed on older hardware.

Strengths
  • — IP65-certified water and dust resistance
  • — 3-meter drop resistance for durability
  • — AES 256-bit hardware encryption for data security
Watch-outs
  • — Silicone exterior casing attracts dust and lint
  • — Requires 10Gbps USB port for maximum 1050MB/s speeds
