Class 10 SD card not enough: some benchmark results

I benchmarked some of my SD cards last night, and knowing that with my fastest cart the Samsung NX20 can write about 20 MB/s, I wanted to see which of my memory cards were fast enough.

Write speeds of various cards (continuous, not burst) using USB3 card reader/writer.

  • Samsung 32 GB Class 10: 11 MB/s
  • Samsung 32 GB Pro 40 MB/s (UHS-I): 31 MB/s
  • Sandisk 16 GB 30 MB/s: 18 MB/s
  • Sandisk 16 GB 95 MB/s (UHS-I): 60 MB/s (I don't have exact figure for this card on me, but over 60)
