SanDisk Extreme 80MB/s UHS-I U3 128GB SDXC Card Review

SanDisk Extreme 80MB/s UHS-I U3 SDXC 128GB Memory Card

Note: The Extreme 80MB/s and Extreme 60MB/s cards are being replaced by a new Extreme 90MB/s line. The new cards are being tested and reviews with speed test results will be posted soon. Preliminary tests of the Extreme 90MB/s 128GB card indicate similar performance to this Extreme 80MB/s 128GB card.

Introduction

The Extreme is the entry level high-performance card from SanDisk. As of 2015, the Extreme line consisted of the Extreme 60MB/s, Extreme Plus 80MB/s and Extreme Pro 95MB/s. The Extreme has long been a popular choice when performance is desired at a reasonable price. In mid-2015, Sandisk introduced the Extreme 80MB/s in 128GB and 256GB capacities with 80MB/s read speed and 60MB/s write speed. These cards are positioned in the same line as the Extreme 60MB/s cards (60MB/s read and 40MB/s write speed) that are offered in 16, 32 and 64GB capacities since around mid-2014. The Extreme 80MB/s is rated the same as the the Extreme Plus 80MB/s cards, which were available before the Extreme 60MB/s line was introduced and at the time of this review (September 2015) the Extreme Plus 80MB/s are being sold in 16, 32, 64, and 128GB capacities.

The Extreme 128GB UHS-I U3 SDXC card tested for this review is suitable for both high-megapixel digital photography as well as high definition and high-definition video. The card carries the UHS Speed Class 3 (U3) designation that guarantees at least 30MB/s continuous write speed making them suitable for recording 4K video. SanDisk quotes the a maximum 60MB/s write speed. Visually, the card shares the gold label of the Extreme 60MB/s cards.

Performance

In USB 3.0 card readers, the SanDisk Extreme 128GB SDXC card was tested with read and write speed benchmark tests. The highest sequential read speed measured 85.2 MB/s, comfortable above the 80MB/s speed on the label. Its sequential write speed measured as high as 80.4 MB/s. This is impressive considering SanDisk quotes the write speed at only 60MB/s. The 128GB card also performed slightly faster than the 256GB capacity card.
