SanDisk Extreme Pro 280MB/s 32GB UHS-II SDHC Memory Card

SanDisk Extreme Pro UHS-II 280MB/s 32GB SD Card

Introduction

The SanDisk Extreme Pro 280 MB/s UHS-II SD card uses the new UHS-II interface to provide the fastest SD memory card to date. UHS-II cards have a second row of contacts to provide a 4-lane bus and operate at a maximum 312 MB/s speed. UHS-II cards are reverse compatible with standard SD and UHS-I capable devices, but will operate at lower speed. The Extreme Pro UHS-II is available in 16, 32 and 64GB capacities.

Who should consider UHS-II cards? Primarilly those who have UHS-II devices. As of November 2014, the only digital cameras to support UHS-II are the Fuji X-T1 and Samsung NX1 (announced September 2014). See the updated list of cameras that support UHS-II for current cameras. Some recent Panasonic video cameras use microP2 which is the same format as UHS-II. Even if you don't have a UHS-II camera yet, you can still take advantage of the fast download speed UHS-II can provide. A UHS-II card reader connected through a USB 3.0 connection can provide over 200MB/s actual transfer speed.

Performance

Measuring the speed potential of the Extreme Pro UHS-II card requires a UHS-II enabled card reader. When the card was introduced only a few readers were UHS-II enabled. They were the SanDisk Extreme Pro UHS-II Reader, the Kingston MobileLite G4 and the Panasonic Micro P2 reader.

Since the initial review, additional UHS-II card readers have been released. After testing the card is several UHS-II readers, the highest read speed benchmark was 279.3 MB/s. The fastest sequential write speed reached 230.9 MB/s.

Computer hardware, drivers and operating system need to be up to date to experience the best performance. There was a significant increase in USB 3.0 performance after updating from Windows 7 to Windows 8.

In UHS-I card readers that do not support UHS-II, the Extreme Pro UHS-II reverts to UHS-I performance. However it does not support the fastest SDR104 (104MB/s bus speed) variant; it is limited to 50MB/s bus speed. In UHS-I readers, the maximum sequential read speed we recorded was 48 MB/s, while maximum write speed was 46 MB/s. Compare this with the SanDisk Extreme Pro 95MB/s UHS-I card that performs up to 98MB/s read and 92MB/s write in UHS-I mode. Also consider the Toshiba Exceria Pro UHS-II card, which is able to provide UHS-II speed in addition to UHS-I SDR104. We measured the Toshiba UHS-II at 96MB/s read and 92MB/s write performance in UHS-I mode. It was also marginally faster than the SanDisk card at UHS-II speed.

In cameras that do not have UHS-II support, the SanDisk Extreme Pro UHS-II card will operate at UHS-I speed. However this SanDisk card does not support UHS-I mode SDR104, so it will be limited to under 50MB/s speed. If you thought spending extra for the fastest card was a going to make your camera faster, you will have wasted your money. In UHS-I cameras such as the Nikon D800 and D7100 the card is only as fast as the Extreme 45MB/s card: In the D800 its maximum write speed was 29.5MB/s and in the D7100 its write speed was 38.3MB/s. The Canon 7D Mark II reached 39.8MB/s write speed.

Recommendation

For the most demanding high-speed applications, UHS-II has a clear advantage over UHS-I. Its reverse compatibility also assures it will work in existing devices. However, unless you have a UHS-II camera it may be hard to justify the cost of this card. You could spend less and get better UHS-I performance with the SanDisk Extreme Pro 95MB/s UHS-I card. If you want better UHS-I performance from a UHS-II card, you might consider the Toshiba Exceria Pro UHS-II card because it supports SDR104 (104 MB/s bus speed), but the Toshiba card is expensive and hard to obtain outside of Europe or Japan. The SanDisk Extreme Pro UHS-II will still provide high speed downloading of images to your computer.
