SanDisk Introduces Application Performance Class 1 (A1) Memory Cards

4Share

SanDisk has just introduced the 400GB Ultra UHS-I microSDXC Memory Card with SD Adapter, a new microSD card with the Application Performance Class 1 (A1) rating, which can be used in virtually all devices that support microSDXC media, including photo and video rigs, and more. With the A1 rating, this card has been optimized to deliver a faster mobile application performance. This spec also allows the card to manage random IOPS operations so it can quickly open apps and process accompanying tasks such as audio, graphics, saved profiles, and in-app permissions.

SanDisk has built this card with a capacity of 400GB, which provides ample storage space. It is also compatible with the UHS-I bus, features a speed class rating of U1, and supports the Class 10 standard, which provides a minimum write speed of 10 MB/s and certification to capture photos and Full HD video. When downloading content from this card, read speeds can reach as high as 100 MB/s. Also featured is water, shock, temperature, and x-ray protection. If you don’t have a microSD card reader, fear not—an SD adapter is included. If you’ve been looking for a high-capacity microSD card, SanDisk has just delivered with a very worthy option.

Do you have a preferred microSD card you like to use with your mobile or other microSD compatible device? Feel free to share your comments, below.

Haha, maybe this will contain my wife who loves to "machine gun" weddings hehehe..

As someone who wondered how "They" could fit 64MB on to such a small SD memory card, the they went into GBs and up to 128GBs and now to 400, but a bit of a throwback to 10MBS... Something is wrong... 

Someone tell me how they do it and why I need it.

The more GBs the more to download and work on. I have a 64GB in my 1st SD slot and a 32GB in the 2nd, in my DSLR. Add to that the fact that SDs may be on the way out, replaced by XQDs, at least in the FF DSLRs and soon into the APS-C models, Watch for the next Sonys, especially since Sony kept the fastest units for its own logo and is "giving" the slower, but more than fast enough for 4K, to the other brands. We are in the beginning of a big switch.

Remember those skinny memory cards in the 90s. I even forgot the name, eventhough I still have a ext. R/W for it and a CF, somewhere in the house.

I seldum shoot more than 4GB in a day's shoot, as an event photographer/photojournalist, and will keep my 16/32/64* as more than large enough. * 64MB for HD/4K video.

I think you mean SmartMedia cards with a maximum capacity of 128 MB? I had one of those in my Olympus 100RS, but sold it as long as it was still worth something.

I do a LOT of long format events for 128GB for 4K is my minimum. The only downside to the really large cards is when you *think* you forget your discipline and don't offload the materials immediately. Then one day you have 400GB of different events to offload and properly label.
