SanDisk 256GB MicroSD Cards Are Quite Fast, But Only In These Conditions


SanDisk has announced a duo of 256GB MicroSD cards, and they have been listed as follows:

  • 256GB SanDisk Extreme MicroSDXC UHS-I U3 card
  • 256GB SanDisk Ultra MicroSDXC UHS-I card, Premium Edition

While SanDisk has claimed that the top most storage card happens to be the world’s fastest, there are a certain set of conditions that must be satisfied in order for you to get the most out of these cards in terms of speed and reliability.

Here Are The Conditions That Need To Be Satisfied In Order For The SanDisk Storage Cards To Work At Their Optimum Performance

Given below are the speeds that SanDisk claims can be achieved by both of its storage cards:

256GB SanDisk Extreme MicroSDXC UHS-I U3 card

  • Transfer speeds up to 100MB/s
  • Achievable write speeds up to 90MB/s
  • Estimated 14 hours of 4K videos

256GB SanDisk Ultra MicroSDXC UHS-I card, Premium Edition

  • Transfer speeds up to 95MB/s
  • 1,200 photos can be transferred in just one minute
  • 24 hours of Full HD video recording

SanDisk Announces Its 256GB MicroSD Cards – Claiming To Be The World’s Fastest

For the world’s fastest MicroSD card, the transfer and write speeds are based on the following:

  • Internal testing: These speeds were achieved according to the company’s test environment, which to remind you have their results displayed above based on the peak data transfer speeds rather than using average data transfer speeds or real-world environments to conduct such tests. That being said, while you will effortlessly be able to record 4K videos without experiencing a hit in performance, it is highly unlikely that you will be achieving this sort of speed until and unless you manage to replicate the company’s testing environment
  • Performance may depend upon the device’s interface as well

As for the lesser performing brother, the 1,200 photos that managed to get transferred in just 60 seconds was the result of outside help as well. SanDisk states that these results were obtained after transferring 4.1GB of data, with the average size of each photograph possessing a file size of 3.5MB and the interface used was a USB 3.0 card reader. Keep in mind that the amount of time it takes will also depend upon the size of each photo, but transferring 4.1GB of space through a USB 3.0 card reader is not bad by any means.


Pricing And Availability

The 256GB SanDisk Ultra MicroSDXC UHS-I card, Premium Edition, will be available worldwide in August 2016 with a price tag of $149.99 while the faster brother will be available worldwide in Q4 2016 with an asking price of $199.99. Looking at the price tags, as well as the conditions that the company set in order to carry out and obtain the test results, do you feel that these storage cards will be worth the money when they officially arrive?
