Samsung PRO Plus 128GB microSDXC vs SanDisk Extreme 64GB microSDXC

Buy the Samsung PRO Plus 128GB if you want more room and faster writes: it doubles the capacity and writes at 120 MB/s versus 90 MB/s on the 64GB SanDisk Extreme. The SanDisk Extreme 64GB has a longer track record and a slightly higher rating from far more owners, and it is the safer pick if 64GB covers your use. Both are UHS-I U3/V30 cards that handle 4K video; the Samsung's A2 rating and higher write speed make it the better fit for heavy app and burst-photo use.

  • Choose the Samsung PRO Plus 128GB if you shoot lots of 4K video or large photo bursts and need the extra capacity and faster sustained writes.
  • Choose the SanDisk Extreme 64GB if 64GB is enough for your phone, drone or action camera and you want the card with the widest owner feedback.

What reviewers say

Samsung PRO Plus 128GB microSDXC

  • 4.7 / 5404 ratings

Owners and reviewers rate it among the best UHS-I microSD cards, praising real-world write speeds and reliability in cameras, phones and handhelds. Complaints are minor: heat under sustained load and the easily lost adapter.

  • 4K recordingPraisedUsers say it records 4K video without dropped frames in phones, drones and action cameras.
  • ReliabilityPraisedLong-term users in dash cams and security cameras report no corruption or failures.

SanDisk Extreme 64GB microSDXC

  • 4.8 / 53,100 ratings

Owners rate it 4.8 out of 5 across 3,100 ratings, mostly for dependable 4K recording in action cameras and drones and for A2 app performance on phones. Complaints centre on write speed falling during long recordings and on cards running warm in continuous 4K.

Questions and answers

Which card is better for 4K video in a drone or action camera?
Both meet U3 and V30, so both record 4K without frame drops. The Samsung's 128GB holds roughly twice the footage and its faster writes clear the buffer sooner, so it suits longer shoots.
Is the SanDisk Extreme more reliable?
It has a much larger pool of owner ratings at a slightly higher average, which is meaningful evidence. The Samsung has fewer ratings but no pattern of failures, and both carry limited warranties.
Do I need A2?
A2 matters only if you store and run apps on the card, common on Android phones. Both cards offer A2 at these capacities, so it does not separate them.
Will either card hit its top speed in my phone?
Only with a UHS-I reader or a device that supports the full bus speed. In many phones and cameras both cards run slower than their rated read and write figures.
Is the Samsung worth stepping up to over the SanDisk?
Step up if you need 128GB or faster writes for burst shooting and long 4K clips. If 64GB covers your use, the SanDisk is the well-proven choice.
Which lasts longer?
Both use similar flash and carry limited warranties; SanDisk offers a lifetime limited warranty, Samsung a limited warranty of its own. Real lifespan depends more on write volume than on brand.
