OWC Express 2TB
Score: 79/100
Transcend ESD410 2TB
Score: 86/100Rankings
The Transcend ESD410 provides 2 TB of storage with 2,000 MB/s read/write performance, MIL-STD-810G shock resistance, IPX5 water resistance, and 256-bit AES encryption. Sustained write speeds fall after the 64 GB pSLC cache and full speed requires a compatible host. Perfect for field-working videographers needing rugged, high-speed storage.
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.

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.
Professional reviewers such as SSD-Tester and Guru3D highlighted the drive's lightning-fast peak throughput-over 2 GB/s in synthetic benchmarks-and its rugged construction that meets MIL-STD-810G and IPX5 standards. They praised its suitability for high-resolution video workflows but cautioned that sustained write speeds dip after the 64 GB pSLC cache is used up and that full performance requires a USB 3.2 Gen 2x2 host.
“"incredible"”
“"maximum offload speeds faster than Thunderbolt"”
