If you record 4K content you must be well-aware that the speed of your memory cards matters. Of course it all depends on compression and if your camera is using a codec with a low bitrate, standard memory cards can be more than enough. But if the codec offers really great image quality, you are forced to invest in fast memory cards - and this is usually the case with 4K content. SanDisk, one of the leaders on the market, announced today a new suite of 256GB microSD cards, which includes the new 256GB SanDisk Extreme microSDXC UHS-I card – the fastest microSD card in its class. It also includes 256GB SanDisk Ultra microSDXC UHS-I card, Premium Edition, the first 256GB card optimized for mainstream consumers. The huge write/read speeds will allow you to capture professional-grade 4K videos without worrying about running out of space on their device. According to the company, you will be able to record up to 14 hours of 4K UHD video on one single card!
The 256GB SanDisk Extreme microSDXC UHS-I card delivers transfer speeds of up to 100MB/s and write speeds of up to 90MB/s - sounds like a perfect choice for owners of such 4K cameras as the Panasonic GH4. Prices also seem to be reasonable - The 256GB SanDisk Ultra microSDXC UHS-I card, Premium Edition, will be available worldwide in August 2016 for the suggested price of $149.99, while the 256GB SanDisk Extreme microSDXC UHS-I card will be available worldwide in calendar Q4 2016 for the suggested price of $199.99.
