Pick Samsung T5 Portable SSD 2TB if

More capacity — 2,000 GB vs 1TB (sandisk.com, bestbuy.com)

Skip both if

Neither publishes endurance, DRAM cache or warranty yet.

The SanDisk Extreme Portable SSD 1TB relies on a ruggedized aluminum housing with IP55 water. And dust resistance, read speeds listed up to 1050 MB/s, and a relatively thick profile that adds noticeable bulk to a backpack or pocket. In contrast, the Samsung T5 Portable SSD 2TB uses a slim anodized aluminum unibody that measures just 74 mm by 57 mm by 11 mm, delivers sequential reads around 540 MB/s according to manufacturer specifications. And doubles the capacity while staying lighter overall. Public reviews consistently note the T5’s smaller footprint. And lower street price per gigabyte, although both drives run cool under sustained transfers and draw minimal power from a single USB-C connection. Neither manufacturer publishes official TBW endurance ratings, DRAM cache details, or warranty lengths beyond the standard two to three years, leaving long-term reliability judgments to aggregated user reports that show comparable real-world performance in everyday file transfers. Bottom line: the Samsung T5 Portable SSD 2TB remains the clearer value for users who prioritize capacity, compactness, and cost over the SanDisk’s extra physical protection.

Verdict: Pick SanDisk Extreme Portable SSD 1TB if you need verified high‑speed read/write performance (up to 2000MB/s read, 1700MB/s write). Pick Samsung T5 Portable SSD 2TB if you want twice the storage for $200 less. Neither publishes endurance, DRAM cache or warranty yet.

SanDisk Extreme Portable SSD 1TB lists at $449.99 while Samsung T5 Portable SSD 2TB lists at $249.99 — Samsung T5 Portable SSD 2TB undercuts SanDisk Extreme Portable SSD 1TB by $200 (80%).
