The 1TB Superior UHS-I microSDXC Memory from Silicon Power keeps up with the pace of your life, allowing you to capture Ultra HD 4K and Full HD video, as well as raw and JPEG stills and bursts. Built with a storage capacity of up to 1TB, this card features a maximum read speed of 100 MB/s, a maximum write speed of 80 MB/s, and a thanks to its V30 / U3 rating, write speeds are guaranteed not to drop below 30 MB/s. If your device does not support V30 / U3, there is backward compatibility for Class 10 / U1 devices. Aside from support for UHS-I, V30, and U3, Silicon Power built this card with support for the Application Performance Class 2 (A2) spec, which includes optimizations to give Android users an improved mobile experience, delivering faster mobile app performance. The A2 spec allows the card to manage random read input-output access per second (IOPS) operations so it can quickly open apps and process accompanying tasks, such as audio, graphics, saved profiles, and in-app permissions. Designed and tested to withstand harsh environments, Silicon Power's 1TB Superior card is resistant against water, shock, and x-rays, as well as temperature extremes of 32 to 158°F. It can also endure a minimum of 10,000 insertions. So that this card may be used in SD-compatible devices, a microSD to SD adapter is included.

Abnormally slow read and write after normal 2 weeks of use with DJI Action Pro 5, security cam recorders, drone.. Eventually won't read anymore just now. Swapped to another same SP card and different brand, recorded and playback flawlessly. I can't trust this kind of media. Returning all these batch. The integrity of footage recorded is far more valuable than saving $30 vs other brands. I would NOT use this on anything important.

As the title states, it's a small and convenient item that's flexible for connections and has a HUGE amount of storage capability. The price ain't bad either! It's simple and straight forward. Give it a try, I don't think that you'll be disappointed.

I've been a Samsung EVO Select devotee for a couple of years. They work well in cameras, giving really good read speeds for downloading photos. However, cameras and read speeds aren't the only use and metric for a memory card. Come to find out, the EVO Select isn't good at all for writing lots of small files in the range of 4 to 6 MB. Think of putting lots of MP3s or MP4s (music) on the card for on the go listening. With lots of files in the 4 to 6 MB range, speed is abysmal; in the 25 MB/s range. Thousands of files will take quite a while.Here's my surprise. The Silicon Power Superior U3 A2, 256GB in my case, gobbles up those same files at around 50 MB/s. Yes, double the speed. Less expensive, just as fast on large files, and double the speed on smaller files? ... MoreI've been a Samsung EVO Select devotee for a couple of years.
