UHS Speed Class was introduced in 2009 by the SD Association and is designed for SDHC and SDXC memory cards. This, again, means that both of these cards will guarantee a minimum of 30Mb/s in the worst-case scenario. If you use a UHS memory card in a non-UHS host, it will default to the standard data bus and use the “Speed Class” rating, which in this case is Class 10, instead of the “UHS Speed Class” rating, which is U3. UHS memory cards have a full higher potential of recording real-time broadcasts, thereby capturing large-size HD videos and extremely high-quality professional HD.

Video Speed Class or “V Class” was created by the SD Association to identify cards that can handle higher video resolutions and recording features. This speed class guarantees minimum sustained performance for recording video. This means that both of these cards will guarantee a minimum sustained speed of 30Mb/sOne of the most-asked questions is: How much storage capacity do I need? Should I buy the 128GB or minimize my investment and buy the 32GB? To be honest, there is no right answer to this question. It all comes down to your needs, My personal preference is to get 4 x 32GB instead of 1 x 128GB. Put critical files in a vault folder to help keep them away from prying eyes with SanDisk SecureAccess™ encryption software 3. Speed Class is a minimum speed based on a worst-case scenario test, which means that both of these cards will guarantee a minimum of 10Mb/s. Compared to high-megapixel photography, video doesn’t need as big of a data pipe because the video format is a smaller “fixed stream” that uses only a portion of the data pipe. Also, your camera’s specifications should state the minimum Class Rating required.
