Rating and Price

  • Rating: 10/10

microSD memory cards offer the benefit of easily expand storage capacity for mobile devices (and even laptops) easily and relatively cheaply. With more and more demanding applications such as 4K video recording, more and more users pay close attention to the performance of the memory cards they buy. That is where the new Samsung EVO Plus microSDXC offering is interesting: it offers theoretical speeds of 100/90 MB/s (R/W)* which is pretty much the best you can get on a UHS-I card today.

The new Samsung EVO Plus is available in 32,64,128, and 256GB capacities and prices are respectively $29.99, $49.99, $99.99 and “undecided” for the 256GB version. If you compare this to having a phone or tablet with more memory, the savings are considerable.

To be fair, internal storage is much faster than current memory cards (hence the price premium), which is why having a fast memory card can make up for some of the performance gaps. The ultimate goal being to avoid perceived performance differences as much as possible.

Specifications

Let’s take a quick overview at the technical specs to have a lay of the land. This Samsung EVO Plus microSD card is a Speed Class 10 (“Class 10”), UHS-I Class 3 (U3) card that uses the latest standards to provide high-performance storage. We are testing the 128GB version here, and unfortunately, those specifications are pretty confusing when you do not know what each logo or rating means. Here’s a quick decoder:

Speed Class 10 is currently the highest “Class” rating available. It is a rating put together by the SD Association to provide a guideline about the minimum read/write speed that any Class should reach.

UHS-I Class 3 (read UHS Grade 1, Class 3 ) determines how fast the bus speed is. UHS-I has a range of 12.5 to 104 MBps, and this card is at the high-end of that spectrum, with the Class 3 (U3 logo) being the best available today.

For example, (Speed Class 10 + UHS-I Class 1) guarantees that the card will record 1080p video. (Speed Class 10 + UHS-I Class 3) allows for 4k 60FPS video recording.

*Important note: the theoretical write speed of 90 MBps is only applicable for the 128GB and 256GB versions. Smaller capacities will cap at 60 MBps.

Samsung EVO Plus microSD industrial design

Usually, people do not pay too much attention about how good the packaging or “board” is when buying memory cards. However, with the rise of waterproof phones, wearable cameras (GoPro, Sony 4K ActionCam) and drones, the physical toughness of the memory card can matter very much since the device can land in water and stay exposed to elements until retrieved.

The Samsung EVO Plus microSD is rated to be waterproof, magnet-proof, temperature resistant and impervious to X-Rays. Depending on your specific usage, this kind of toughness is worth paying attention to since you may avoid content loss.

  • Operating temperature: -25C to 85C
  • Non-operating temperature: -40C to 85C
  • IPX7 waterproof rating (rated for water immersion, but not dust protection)
Overall product rating: 10/10
