They are actually two flash storage solutions aimed 4K shooters, offering different performance levels, as you see below:

Starting with the Exceria M303 microSDXC line up, in addition to UHS Speed Class 3, it is equivalent to Video Speed C lass 30. The series comes in capacities up to 256 GB - perfect for 4K video recording in fast and tought situations as well as for capacity expansion for your smartphone. The EXCERIA M303 is also compatible with the latest SD Association's A1 Application Performance specification Version 5.1, with the expanding needs of utilizing microSD memory card, usually used as external storage device, as internal storage for mobile device such as smartphone.

The line up supports maximum read/write speeds of 98MB/s and 65MB/s respectively. In addition, rated with Video Speed Class 30 (V30), the M303 provides a minimum data transfer rate of 30 MB/s with a recommended UHS device under the conditions regulated by SD association.

The series is made for hard conditions: waterproof, shockproof, X-Ray proof and temperature proof. The SD adapter included with the M303 Package gives you a wide variety of use options.

The M303 is utilising Toshiba Memory Corporation’s 3D Flash memory technology (BiCS FLASH). Operating at a temperature range of -25˚C to +85˚C, the M303 is shockproof, X-ray proof, and waterproof. The M303 cards come with a five-year warranty.
