  • UHS I / U:3 (EVO+), Class 10 cards
  • Waterproof
  • Magnet proof
  • Temperature proof

To test the read and write times of these cards, we used a USB 3.0 card reader and CrystalDiskMark 3.0.1 x64. For digital cameras, the write time is the most important aspect as this determines how quickly you can write photos from the camera to the card. The read time is important when you want to copy the photos from the card onto your PC or view them in playback mode on the camera.

Read MB/s Write MB/s
Samsung EVO+ 256GB MicroSDXC UHS I U:3 Class 10 92.16 84.81
Samsung PRO+ 64GB MicroSDXC UHS I U:3 Class 10 94.34 84.14
Sandisk Extreme Pro 8GB SDHC UHS I U:1 Class 10 51.08 42.58
Samsung EVO+ 128GB MicroSDXC UHS I U:1 Class 10 88.70 26.98
Leef Pro 16GB MicroSDHC UHS I U:1 Class 10 31.99 7.082

While read and write speeds from the Samsung EVO+ MicroSDXC card are not as quick as specified on the box, the card does deliver extremely high read and write speeds, and slightly quicker performance than the Sandisk Extreme Pro card. The Samsung card is also quicker than a number of other high-speed cards.

Value For Money

The Samsung EVO+ 256GB MicroSDXC card is available for £175/$262, compared to £129/$193 for a 256GB Sandisk Ultra. The Samsung EVO+ 128GB MicroSD card is available for £62.99/$94 with the adapter, compared to around£51.99/$78 for a 128GB Sandisk Ultra with adapter. These cards are pretty evenly matched, with the Samsung edging it giving a 10 year warranty for peace of mind.

The Samsung EVO+ 256GB microSDXC memory card offers some of the fastest read and write speeds available as well as offering a 10 year warranty that is also backed up by the card being waterproof, temperature proof, x-ray proof and magnet proof making it much more likely to survive when compared to more fragile cards. We would therefore be happy to recommend the Samsung EVO+ microSDXC memory card, particularly if you need the storage space.
