Sony M Series 32GB SDHC UHS-II U3 Memory Card Review Review

Sony M Series 32GB SDHC UHS-II U3 Memory Card

Introduction

Sony M Series offers a less expensive alternative to the top-of-the-line G Series UHS-II memory cards. The M Series SD cards use UHS-II technology to deliver an extremely high read speed of 260MB/s and write speed of 100MB/s according to Sony. The write speed is similar to other fast UHS-I cards but the read speed makes transfers to a computer nearly three times as fast as the fastest UHS-I cards. This UHS-II card is backwards compatible and will work in UHS-I and standard SD cameras and other devices, although its speed will be limited by the device.

The M Series 32GB SDHC card is UHS Speed Class 3 (U3) rated, meaning it can maintain at least 30MB/s continuous write speed for HD and 4K video recording. This M Series SD card is also suited for DSLR cameras where its 100MB/s write speed will support long continuous shooting bursts. Sony M Series SD cards are offered in 32, 64 and 128 GB capacities. The 32GB SDHC card model SF-M32/T with UPC 027242898080 is tested in this review. The box has a sticker 2017-03 and a green dot on the back of the package.
