Transcend ESD410 2TB
Score: 86/100
Corsair EX400U 2TB
Score: 84/100Rankings
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 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.

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.
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.
