Designed for photographers and digital media professionals, the PRO Ultimate UHS-I SD Memory Card from Samsung features a storage capacity of 128GB and takes advantage of the UHS-I bus to support read speeds up to 200 MB/s and write speeds up to 130 MB/s. Its V30/U3 class rating guarantees write speeds won't drop below 30 MB/s, making it suitable for 4K, Full HD, and 3D video, as well as raw and JPEG captures, plus rapid shutter bursts.

As with most Samsung cards, this memory card is resistant to water, X-rays, magnets, drops, shock, and wear. It is also able to withstand temperatures from -13 to 185°F so you can take it with you into extreme environments, including snow and deserts.

Q: 9. I was given this reader as a gift,but when using it with my late 2013 mac pro and uhs-II cards or cards in general it is very slow. In fact my old non uhs-II reader is faster. Is there a solution for this?

A: Currently, using USB 3.1 cables and ports and UHS-II SD memory cards, is one of the fastest ways to transfer photos available. It is likely that your computer does not have USB 3.1 ports available so these high speeds will be slowed by the much slower computer and ports being used. Whichever is the slowest link in the chain will throttle all of the others to its speed.

Q: 10. can I use this in a Gopro?

A: Yes, you can. You can also put 150MPH racing tires on a sedan. I suggest a more affordable moderate performance card like the SanDisk 64GB Extreme PLUS UHS-I microSDXC Memory Card with SD Adapter B&H # SAEPMSD64V3. You will see no difference except in your wallet.
