Netac 2TB Portable SSD
Score: 68/100
Corsair EX400U 2TB
Score: 84/100Rankings
The Corsair EX400U 2TB delivers blazing USB4 performance up to 4,000 MB/s read and includes MagSafe compatibility in a tiny 64 mm square case. It lacks an IP rating and rugged drop protection, and carries a premium price. Perfect for professionals needing near-internal speeds on modern USB4 devices.
The Netac ZX20 2TB Extreme Portable NVMe SSD provides a feather-light, pocket-sized form factor with up to 2000 MB/s reads when paired with a USB 3.2 Gen 2x2 host. Its limitations include reliance on rare host ports for peak speeds, a plastic enclosure without IP protection, and a higher price point. It is best for mobile professionals who value ultra-light weight and high capacity over ruggedness.

Professional reviewers commend the Netac ZX20 for its feather-light weight, compact size, and useful cable bundle, noting it delivers solid performance on compatible USB 3.2 Gen 2 ports. However, they caution that the advertised top speeds require a rare Gen 2x2 host, the plastic enclosure feels flimsy and lacks any IP protection, and the price is higher than comparable models with similar capacity.
Everyday users appreciate the drive's portability, lightweight feel, and the convenience of the included cables, but they frequently express disappointment when the real-world speeds fall short of the advertised 2000 MB/s and criticize the cheap-feeling plastic housing and the absence of an IP rating.
Professional reviewers praise the EX400U for its tiny footprint, blazing USB4 performance, and hassle-free plug-and-play experience. The inclusion of a full-length 40 Gbps cable and the ability to operate without a separate power brick were highlighted as strong points, while the drive's speed is consistently described as comparable to internal SSDs.
