SD cards with speeds of 624 MB / s: the UHS-III standard arrives

[OyaYansa]

At a time when digital photography is advancing by leaps and bounds, the ability to record and transfer image data at high speeds is imperative. However good it may be - for example - the 4K camera we use to immortalize a scene, it is essential to use an external memory card that is capable of processing the data at the speed required by the most modern image formats.

The SD Association, the organization that regulates the standards of external storage cards, has announced the UHS-III, the format that will help to transfer large amounts of data to a SD card generated by 3D cameras, drones and 4k video cameras to A speed of 624 MB per second. The UHS-II (the standard under which nowadays most of the external memory cards work), in turn, does not exceed 200-300 MB / s of transfer speed.

UHS-III is a specification dictating the speed of data transfer between the SD card and a device. Precisely this week has been Sony which has presented a microSD card that beat all speed records under the previous standard, the UHS-II, with a writing speeds of up to 300 MB / s.

The UHS-III standard now occupies the position of the fastest speeds in the market for external storage cards, since to be exact it will double the data transfer rates in relation to the previous UHS-II format that allowed to reach the 312 MB / s.

The UHS-III will be compatible with both SDXC and SDHC as well as the older SD specifications, ie it will work with all the SD currently on the market, although the performance would be higher with the first two configurations.

The storage capacities of the latest cards are larger and allow you to save more photos, as well as use unique video features in the latest camera models. In this sense, UHS-III will help to organize these contents more quickly and smoothly.

The UHS-I announced in 2010 began opening the world of ultra-high speed with 104 Mb / s, which tripled with the UHS-II of 312 Mb / s and will reach its peak with the UHS-III of 624 Mb / s .

Both the first and the second make the storage more manageable and portable. The size and shape of the cards would not be modified with the UHS-III since only one aspect of the PHY would be changed. The UHS-III, therefore, is positioned as one of the best specifications of SD and undoubtedly the fastest and most powerful of the moment.
