Overview of two high-capacity memory cards: microSDXC 128 Gb and SDXC 256 Gb
Hi, Giktayms! Memory cards are needed by absolutely everyone, except perhaps the owners of smartphones and tablets with bitten apples. One of the world leaders in the production of memory cards is the company Kingston. And now the moment has come to conquer new volumes of memory cards - SDXC for 256 gigabytes and microSDXC for 128 gigabytes. Under the cut - the story of the updates.

It’s very easy to talk about the advantages of such cards: these are huge collections of movies and music in Android tablets and smartphones and a huge amount of hours of recording in DVRs and action cameras.
In addition, I note that a card of this volume at the same time is a way to lose all the material at once, for example, in the case of a quadrocopter falling into water.
Recording speed is extremely important for high resolution cameras, and in fact according to this parameter they divide memory cards into classes. The test specimen is declared as class 10 UHS-1, which means it must demonstrate a write speed of at least 10 MB / s. Of course, we should expect that this threshold is exceeded, in fact, we will check in the tests.
And here's a nice truth, the map is really faster than the stated standard
Owners of SLR cameras already probably rub their hands, although frankly speaking, 128 gigabytes was often enough even for long journeys. If the photographer is actively using video recording, in this case you need to think about the maximum amount of memory card. The card standard is declared as class 10 UHS-1, which means it must demonstrate a write speed of at least 10 MB / s. Smaller for recording FullHD video is simply not allowed, but there is still high-speed shooting in the SLR, and there the flow of information is much more.
What can limit a person when working with such cards?
Actually the speed of the camera and the speed of data transfer to a computer through a card reader. To eliminate the potential bottleneck I will take the original Kingston device for reading and writing to memory cards, at the same time it will be possible to evaluate this device.
The device by the way is made very competently. Support for a heap of standards for memory cards does not surprise anyone anymore, but not every vendor puts a long USB cable in the kit.
A bit annoying is the red Kingston logo, which is actively flashing during operations with the inserted card, but the light is not very bright, and you can easily turn the reader over.
By the way, remember there was a post about the MobileLite Wireless Gen2 wireless card reader? So, the marked memory cards kindly agreed to go through the testing procedure in this device. In a warm and friendly environment, all the information that was recorded on SDXC 256 Gb and microSDXC 128 Gb was shared on the connected iPhone and tablet on the android. “Prank failed” (C) Harry Potter.
Testing in real life was carried out for microSDXC in the Sony HDR-AS100V camera , and for SDXC - in a Canon 6D reflex camera.
When shooting a video on an action camera, no problems were noticed, the card coped with all the tasks and the frame rate - 120 frames per second at a resolution of 720p and at a frame rate of 240 at a resolution of 480p. But for shooting in the XAVC-S format with a data transfer rate of 50 Mbps, you need a faster card, for example, the Kingston SDA3 , but it has twice the capacity.
Burst shooting on SDXC 256 Gb in Canon 6D was a success. At a shooting speed of 4.5 frames per second, the card took over 28 frames in 15 seconds. This is not a record figure, Kingston has faster SDA3 cards - but their capacity is limited to 64 gigabytes.
Summing up, I’ll say - 10 years ago, cards with a capacity of 1024 times smaller were considered large, and the recording speed of 4-5 MB / s was the height of dreams, progress does not stand still, flash memory progresses continuously, and leads in this process, of course, Kingston company.
