SanDisk Ultra microSDXC UHS-1 256GB Snap Verdict

I’m constantly amazed at the increasing size of flash memory, and at 256GB this is one of the largest capacity cards I’ve ever used. This capacity is even more incredible seeing as how the SanDisk Ultra microSDXC UHS-1 is a MicroSD card.

It’s the size of my thumbnail, weighs a couple of grams and can store up to 170 typical two-hour movies.

Tested in the latest range of products including the GoPro Hero and Removu K1 the card worked like any other, no hic-ups, just direct reliable storage.

The price may make you wince at around £118 for the 256GB version, but then you’re unlikely to need another card for a very long time.

Against SanDisk Ultra microSDXC UHS-1 256GB

  • Can easy get lost
  • Capacity excedes compatibility with some devices

This type of large capacity card has existed for quite a while, and there are even cards that make this card look small in comparison, but to me 256GB is huge.

What’s more that’s capacity comes in the form of a MicroSD card, that’s minute.

I haven’t truth be told had the greatest success with MicroSD cards, they’re really small, and some action cameras come equipped with over-enthusiastic springs in the card slots.

How to get started with video

What this ultimately means is that if you’re not careful the MicroSD card that contains your amazing footage; base jumping from the Eifel tower, out skiing an avalanche and let’s not forget riding the ultimate 100-foot wave has, unfortunately, all been fatefully lost.

OK maybe that’s an exaggeration, but seeing how far you can fire a microSD card across a room is a great way to while away a dull afternoon.

However at 256GB and costing well over £100 I felt inclined to take care of this MicroSD card like no other card I’d ever had.

Testing MicroSD cards is pretty straightforward, pop the card into a few devices and check that it works.

Go out and use the card in earnest and check that it doesn’t melt, snap or do anything that it shouldn’t.


This card falls into the mid-Ultra range of SanDisk cards; these cards are an ideal solution for anyone buying the GoPro Hero.

The card is optimised for use when filming Full HD, and features speeds of up to 95MB/s, that speed refers to the read speed, write speeds are unquoted on either the packaging or website.

SanDisk Ultra microSDXC UHS-1 256GB Review

The card features the Ultra range’s usual split grey and red design, a feature that I’m a big fan of as it makes finding them easier after they ping out of your device, although that colouring is only on one side.

The card is available in two capacities either the 256GB version, the one I have on test, or a 200GB version.

The form factor of the card is MicroSDXC and it has a video speed of C10, meaning a minimum write speed of 10MB/s.

As well as the MicroSD card you also get the SD card adapter that enables you to directly mount the card into any computer with an SD card slot.
