Netac 2TB Portable SSD
Score: 68/100
OWC Express 2TB
Score: 79/100Rankings
The OWC Express 1M2 offers up to 3836 MB/s USB4 performance in a rugged aluminum enclosure with a patented heatsink and upgradeable M.2 SSDs. Its larger size and potential heat under sustained loads are drawbacks. It targets pros who need fast, future-proof portable storage.
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 Express 1M2 for its blistering USB4 speeds, robust aluminum heatsink that prevents throttling, and the flexibility of a user-replaceable SSD. They position it as a high-performance tool for DITs and video editors needing fast off-loads, while noting the trade-off of increased size and heat under sustained load.
Early consumer feedback is limited but generally positive, highlighting the fast transfer rates, lightweight empty chassis, and easy plug-and-play use. Common concerns revolve around heat generation, the need to reformat for Windows, and the lack of extensive user reviews due to its recent launch.
