Silicon Power gave us an opportunity to try out their newest memory cards, the Superior UHS-1 flash cards. Let’s test this card and find out if the card is in fact ‘superior’.


Before we start, let’s take a look at the features and specifications:

  • Capture high-quality images and extended lengths of stunning 1080p full-HD video with any SD UHS-1 compatible DSLR, camera, HD camcorder, 3D camera
  • Powerful Transfer speeds, reducing lag time while photo-shooting:
  • Superior series
    • up to 90/45 MB/s reading and writing (SDHC UHS-1)
    • up to 85/40 MB/s in reading and writing (SDXC UHS-1);
  • Class 10 video recording performance
  • Getting 10 more photos in consecutive shooting in JPEG by a UHS-1 supported device


  • Form factor: SDHC (16/32 GB) & SDXC (64 GB)
  • Card dimension: 24 mm x 32 mm x 2.1 mm
  • Operating temperature: 0ºC to 70 ºC
  • Storage temperature: -40ºC to 85ºC
  • Compatible with SDHC / SDXC UHS-1 enabled host devices.



Take note that we are using the 64 GB version of the UHS-1, we tested the unit from several event coverage with the combination of photos and videos. With such capacity, it can hold up to 8 hours of video footage with 720p HD quality and around 15,000 images, all in JPEG format from a 10 megapixel camera.

Reading and writing speed of the UHS-1 is really good, especially when recording really long videos where some cards would take a while before they can complete the writing process. This is a real help for photographers and videographers for long session shoots as they don’t need to bring extra cards

We even tried using the unit as a portable storage device, and with 90 Mbps reading speed, you can enjoy watching videos straight through the card, even transferring files was a breeze.

All in all, the Superior UHS-1 SDHC card is a great arsenal to your gear, whether you’re a photographer or just someone who needs a fast and large portable storage.
