What customers say about "Key Specs"
Lexar Professional 667x 128GB SDXC UHS-I/U3 Card
  • This is an excellent card for the money. It is around 92MBps read and around 80 MBps write speeds on sequential transfers with my USB3 card reader.
  • Transfer speed is impressive, I have no complaints at all.
  • Storage capacity more than ample - for most recording I use 1080p, and after 45 minutes of video, it still has plenty of capacity left.
  • It basically maxes out the UHS-I bus and will be difficult to get any faster speeds.
  • The transfer speed to your computer is horrendous.
SanDisk Extreme PRO UHS-I 128 GB SDXC Memory Card
  • Read and write speeds cope with the 4K video and also writing 30MB raw files in high speed bursts without a flutter.
  • This card is a good price for this speed rating.
  • The data transfer speed is lightning quick.
  • Nice file transfer speeds and no glitches.
  • Very good writing speed and storage space is excellent.
