While both microSD cards come in multiple sizes, the Samsung EVO Select is the better choice for 4K recording while the SanDisk Ultra offers better value for those who don’t record in 4K.


Samsung EVO

A great inclusive option for the best microSD cards is this Samsung MicroSD EVO Select.

At 32GB, it offers substantial storage for your tablet, smartphone, and travel camera, giving you the right amount of space needed to keep up to date with the latest apps, and not worry about low storage space, at least not for a while, anyway.

As a Class 10 card, it guarantees read speeds of at least 10 MB/s, and Samsung boats an optimum speed as high as 95 MB/s, speeding up your data transfer activities and giving you a chance to move on quickly.

For versatile storage and transfer options, it also comes with a full-size SD Adapter, adding an extra level of data protection with its durable design and construction.


  • Fast Read and Write Speeds.
  • Lots of environmental protections.
  • Multiple storage sizes.


  • Only available at Amazon.
  • Speeds can vary.

SanDisk Ultra

Ideal for Android smartphones and tablets, this SanDisk 64GB microSDXC is a next-level storage device acting as much more than a mere memory card.

On top of the fast read/write speeds, it comes with built-in data protection in the form of the RescuePRO Recovery Software.

We all know how devastating it can be to lose all your data without warning, nor doing anything wrong – it’s devastating when you have done something wrong, but at least you can place the blame somewhere – so this offers peace of mind you may never have had with an SD card before.

Besides this, the SanDisk Memory Zone gives you an easy file organization, which is great news for those who take more pictures than they can keep up with.

To sweeten the deal, it supports 4K recording and comes with a lifetime warranty, so there’s (pretty much) no limit to what you can record and store.

  • Excellent value for money.
  • Huge choice of storage options.
  • Can get it almost anywhere.


  • Only U1 not U3.

Is Samsung EVO Select or SanDisk Ultra a better microSD card for you?

To choose the right microSD for you we need to look at your use case. Unless you are specifically going to be recording video in 4K then the SanDisk Ultra is a better choice.

At $26 for the 128GB version it is the cheaper option, and while not being as fast as the EVO Select, the choice in sizes gives you far more options.

Of course, if you do intend to record video at 4K then choose the EVO Select. The faster write speed is invaluable for recording great 4K video.

The breakdown

As you can see from the spec list the EVO Select and the SanDisk Ultra have similar read speeds but the biggest difference is in the write speed.

That’s because the SanDisk is only classed at U1 instead of the U3 of the Samsung.

The U Number tells you what class the microSD is when connected to devices using the UHS transfer bus.

It’s technical, but generally the higher the number the faster the write speed from the device to the card.

As the SanDisk only has a U1 rating it can only write data and around 10Mbps, which is perfectly fine for DSLR cameras capturing RAW files or taking pictures on your phone, but won’t really be sufficient for recording in 4K on something like a GoPro.

The Samsung Evo Select, however, has a U3 classification, which means it is capable of much higher write speed, around 90Mbps, and is the best choice if you are recording 4K video on any device.

While the Samsung is the faster of the two microSD cards the SanDisk does come in many more size choices.

While it feels it would be better to always go for the biggest capacity, it may be better to select several smaller cards to make sorting media easier.

The EVO Select comes in four sizes while the SanDisk comes in seven, including a massive 400GB model.

The Bottom Line

I hope you have choose the right SD card for you.
