When buying a micro memory card, it is crucial to know that speed is one of the vital elements to check out. The rate exhibited by a model should be appropriate for the type of hardware that you intend for its use. The listed transfer speed is among the first that you ought to assess.

The UHS Bus speed is the next one that is essential to consider since it informs you on how data is transferred from the card’s pin to the connector of the host device. Unlike the listed transfer, the UHS Bus speed may not be explicitly listed in the features. It is indicated on the face of the card using roman numerals.

The Ultra Plus and Extreme SanDisk models both have a UHS Bus speed of (I). The theoretical maximum transfer speed for both cards is therefore 104mbps.

The video speed class is another aspect that you cannot overlook. It is indicated using a V icon on the face of the memory card, and it is for video-specific recording. The 64GB SanDisk Ultra Plus product lacks this marking; hence, it may not be an excellent pick for video recording.

The 128GB version is a V10 meaning it can record videos at 10MBps. The SanDisk Extreme cards, on the other hand, have a V30 marking on all the sizes starting from 32GB to 1TB. They can be used to record a high definition video comfortably.

The UHS rating for the SanDisk Ultra Plus model is one while that of the Extreme variation is three. The number inside the U-shaped logo can identify this type of speed.

The technology used to design a memory card dictates its functionality. The SanDisk Extreme has been made with Ultra DMA technology that allows this device to achieve double read and write speeds when compared to the SanDisk Ultra Plus.
