This is insane! True, we didn't quite get the same speeds that SanDisk announced, but it's still ridiculously fast. We got an 80 MB/s write speed and the read speed went well over 90 MB/s. In real terms this means it takes just 51 seconds to copy a 4 GB file on to it and 43 seconds to copy the file off of it. SanDisk is miles ahead of the competition.
There's just one detail. In order to achieve these speeds SanDisk had to use UHS-1. And right now there are a total of zero tablets and smartphones that support UHS-1. So the cards will work, but your device won't be able to make full use of the card's potential. As things stand today, you can only achieve these speeds if you have a USB 3.0 card reader.
- Amazing speeds (write: 81 MB/s, read: 94 MB/s)
- RescuePro included
- Perfect for professional cameras
- Requires a USB 3.0 card reader
- RescuePro licence expires after one year
This memory card is ahead of its time. The speeds it achieves are bewildering, period. But there's a snag. In order to reach these speeds you need a card reader that has a USB 3.0 interface. Today no smartphones or tablets have that, so they can't fully exploit the Extreme Pro's potential.
