Ariel has been working as a highly professional computer-relevant technology editor at MiniTool for many years. UHS Speed Class was introduced in 2009 by the SD Association and is designed for SDHC and SDXC memory cards.

as real users, posing a threat to a site’s security, so the site sometimes runs random security checks. With a few differences between both of these cards, it all comes down to your needs, if you are shooting mainly video, or if you shoot mainly in a studio tethered to a computer, I would personally recommend going for the cheaper option, which is the Extreme. Video Speed Class or “V Class” was created by the SD Association to identify cards that can handle higher video resolutions and recording features. With the SanDisk Extreme microSDXC memory card, you can capture 4K UHD video recording, Full HD video, and high-resolution photos.

Long story short, I connected both of the cards to my Mac and copied 2GB of data to and from each of them, using a stopwatch. The SD and SDHC memory card is mainly formatted to the FAT file system, while SDXC and SDUC are mainly formatted to exFAT file system.

However, a variety of SanDisk memory cards such as the Extreme, Extreme Pro, and Extreme Plus series let lots of consumers dazzle. Both of these cards were engineered using SanDisk proprietary technology that allows them to reach speeds beyond UHS-I 104MB/s, but ultimately, max speed depends on your device. When I hit the 34-second mark, it started lagging a bit and stopped completely for 2 seconds at the 49-second mark. However, if you are concerned about the transfer rate or if you depend on burst shooting, I would definitely recommend the Extreme Pro simply because it didn’t lag during the test. Work as fast as you need to with premium performance and huge capacities in a portable yet tough and reliable USB flash drive.With the fastest read speed of 170MB/s, SanDisk Extreme Pro microSDXC card wins SanDisk Extreme and SanDisk Extreme Plus. Cost range will vary depending upon Service Level, type of device, cause of data loss, drive condition, and other factors.

After a little time, you will see the test results including transfer size, the random/sequential reading and writing speed, etc. We also publish tips and tutorials about photography, helping everyone become a better photographer. When it comes to a memory card, a great many people take the data transfer speed into their first consideration.Besides, the Ultra lineup can support up to the 512GB capacity, while the Extreme can support up to 1TB. No matter what type of SanDisk memory card you want to choose, you have to manage your SD card effectively. The supported the storage capacity and file systems vary according to different memory card formats.
