Samsung Pro Plus

The best overall — fast, reliable read AND write speeds with U3/V30 (smooth 4K) and A2 (fast app loading) ratings, 6-Proof durability, and Samsung reliability, at a fair price. Pro-tier video wants more write headroom and the cheapest cards cost less, but the sweet spot of real read/write speed, the right ratings, durability, and value for the widest range of uses.

The Samsung Pro Plus combines fast, reliable read AND write speeds, the right ratings for 4K video and demanding use, strong durability, and Samsung's trusted reliability — at a fair price. It delivers high read speeds and, crucially, fast sustained write speeds (what actually matters for recording 4K and shooting bursts, which cheaper cards skimp on), with U3 and V30 (at least 30 MB/s sustained write for smooth 4K) and A2 (faster app loading in a phone), plus 6-Proof durability (water, temperature, X-ray, magnetic, drop, and wear resistant). It hits the sweet spot for the widest range of uses. For the most demanding pro video the SanDisk Extreme Pro or a V60/V90 card has more headroom, and the cheapest cards cost less for light use, but for the best all-round balance of read and write speed, the right ratings, durability, reliability, and value, it's the one most people should buy.
