Transcend ESD410 2TB
Score: 86/100
SanDisk Extreme PRO 4TB USB-C
Score: 85/100Rankings

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 SanDisk Extreme PRO Portable SSD 4TB delivers Thunderbolt-class performance with up to 3800 MB/s read and 3700 MB/s write speeds in a rugged, IP65-rated chassis. Its peak speeds are only reachable on USB4 or Thunderbolt 4 hosts, and it lacks built-in hardware encryption. Ideal for creators needing ultra-fast portable storage.

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 commend the Extreme PRO USB4 SSD for its Thunderbolt-class speeds, rugged construction, and real-world bandwidth that validates the advertised numbers. However, they caution that the full performance envelope is only reachable on USB4 or Thunderbolt 4 hosts, and that 4K random write performance has slipped compared to earlier USB 3.2 models, with endurance data still missing.


Everyday users largely echo the reviewers' praise for blazing transfer rates and the drive's durability, especially for on-the-go creators. The most common complaints revolve around slower speeds on legacy ports and the absence of clear endurance specifications, though no widespread reliability issues have been reported.
