Ranked #3 in Best External SSDs

Crucial X9 Pro

4.0

$89as of May 26

StorageReview and The SSD Review highlight the Crucial X9 Pro as an exceptionally compact and lightweight portable SSD, measuring just 65x50mm and weighing 1.34 ounces. While real-world single-threaded tests showed speeds slightly under the advertised 1,050MB/s, multi-threaded workloads closely matched manufacturer claims, making it suitable for creators needing fast transfer rates. Reviewers also praised its rugged build, citing IP55 water/dust resistance and drop-proof durability up to 7.5 feet. However, users must ensure their host device supports USB 3.2 Gen 2 to achieve these peak speeds, otherwise performance will be capped. This drive is best for professionals prioritizing portability and durability over absolute maximum throughput.

Strengths

— Compact dimensions of 65x50mm and lightweight at 1.34 ounces
— High sequential read/write speeds up to 1,050MB/s
— IP55 water and dust resistance rating

Watch-outs

— Single-threaded performance falls slightly below quoted maximums
— Requires USB 3.2 Gen 2 port for optimal speeds

Samsung T7 Shield

4.2

$479.99as of Jun 7

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
