SanDisk Extreme Plus 80MB/s 32GB microSDHC UHS-I U3 Memory Card Review

SanDisk Extreme Plus 80MB/s U3 MicroSDHC Card

Introduction

The Extreme Plus 80MB/s microSDHC 32GB card offers high performance in a very tiny package. The Extreme Plus is positioned between the Extreme and Extreme Pro. It supports UHS-I and features the UHS Speed Class 3 (U3) designation, meaning it can support at least 30MB/s continuous write for use in 4K video recording applications. Sandisk rates Extreme Plus microSD cards at 80MB/s read and 50MB/s write (except the 16GB version is rated 30MB/s write). The Extreme Plus microSD card is available in 16, 32 and 64 GB capacities. The 32GB microSDHC version is reviewed here.

Performance

The Extreme Plus 80MB/s 32GB microSDHC card was tested in several USB 3.0 card readers. In card readers it was tested in a microSD slot, if available, and in a standard SD slot using the included SanDisk microSD to SD adapter. Speed tests with and without the adapter in readers with both slots provide virtually identical results (microSD to SD adapters are simple pass-though devices).

The microSDHC version of the Extreme Plus outperformed the standard SD card version that was previously reviewed. The microSD version supported about 5MB/s faster write speed, averaging 65.4MB/s sequential write across several USB 3.0 card readers. Sequential reads between the microSD and full size card were similar, with the microSDHC card reaching over 98MB/s in two of the faster USB 3.0 card readers, well above its 80MB/s advertised read speed.

In camera tests the 32GB Extreme Plus microSDHC posted some impressive results. In some cameras it is among the top performing cards. For example, in the Canon 6D SD card comparison it was only behind the Extreme Pro 95MB/s UHS-I, beating many cards with faster write speed benchmarks. Results from additional cameras show that in UHS-I cameras that support UHS-I mode SDR104 (104MB/s bus speed), this card is limited by its write speed. While in other cameras like the Canon 6D only support UHS-I 50MB/s bus speed, the card is not limited by its write speed. Its excellent performance is probably due to a very efficient controller (its sequential read benchmarks are similar to the Extreme Pro 95MB/s card).

SD vs microSD

The microSD version of the Extreme Plus 80MB/s offers the speed and capacity of a full-size SD card in a minuscule package. For devices that require a microSD card size it would be an obvious choice, and in cameras or other devices that have standard SD slots it can be used with the included adapter. There is no speed penalty for using this card in an adapter (its performance is the same with and without the adapter), but the microSD version usually costs more. With more devices such as smartphones and action cameras (GoPro) using microSD cards, it might make sense to purchase the microSD version even if your primary camera uses standard SD cards.
