SanDisk Extreme Portable 1TB vs Transcend ESD310C 1TB — Which External SSD Is Faster & Better Value?
Compare SanDisk Extreme Portable 1TB and Transcend ESD310C 1TB side by side. Both are 1TB USB 3.2 Gen 2 external SSDs, but they differ in speed, design, and value. Here's how they stack up.
SanDisk
The non-Pro Extreme is the lower-cost sibling — same 1050 MB/s rated read and IP55 rugged body, but writes top out well below Extreme Pro on sustained workloads. A solid buy when the write-speed gap doesn't matter (game consoles, file transfer, backup) but the rugged rating does.
Transcend
A tiny 1050-class Gen 2 portable from a long-established memory brand. ESD310C is one of the smallest 1TB Gen 2 SSDs at retail — small enough to be lost in a bag. Buy it for the form factor over sustained performance.
