Samsung T7 Shield comes out ahead by a narrow margin (4.0 vs 4.2). The gap is mostly about fit for purpose — read the strengths below before deciding.

OWC Envoy Ultra
Ranked #3 in Best External SSDs
OWC Envoy Ultra

OWC positions the Envoy Ultra as the world's first Thunderbolt 5 bus-powered 8TB drive, combining rugged durability with high-speed storage for creative professionals. While the hardware itself is highlighted for its compact size and speed, the broader OWC Thunderbolt 5 ecosystem (Stack AI) is noted for enabling local AI model execution on existing PCs and laptops. However, users should note that full AI acceleration support for Mac is currently planned for a future release rather than being available immediately. This product best fits Windows/Linux power users and video creators needing massive, portable storage, while Mac AI enthusiasts may need to wait for 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
  • — Limited to Thunderbolt 5 connectivity

Samsung T7 Shield
$429

The Samsung T7 Shield is praised for its rugged build, offering IP65 water and dust resistance alongside 3-meter drop protection, making it a reliable choice for outdoor or travel use. Reviewers highlight the inclusion of AES 256-bit hardware encryption and the availability of a massive 4TB capacity, which is rare for Samsung's portable lineup. However, the soft silicone exterior is noted as a dust magnet, and users must ensure their host device supports 10Gbps USB to achieve the drive's top transfer speeds of 1050MB/s. This drive best fits users who prioritize durability and security over sleek aesthetics or maximum 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
