Manufacturer description

The DIGIERA 256GB CT100 microSDXC card is a bulk-storage upgrade for devices that fill up fast. Rated Class 10, U3, and V30, it sustains the write floor 4K UHD video recording needs, and DIGIERA's internal testing puts sequential speeds at up to 100MB/s read and 70MB/s write, so moving RAW photo batches or a large game install off the card does not stall your workflow. The A2 rating matters if you run apps from the card: DIGIERA specs up to 4,000 random read and 2,000 random write IOPS, which is what keeps app launches and multitasking responsive on a phone or handheld console rather than…

SpecPicks Verdict

SpecPicks scored DIGIERA 256GB CT100 microSDXC UHS-I Memory Card with Adapter using a rating × review-volume × price-fit model applied to published specs and reviews across the accessories category. DIGIERA's accessories lineup sits within the broader category mid-tier; price and specs are the deciding factors over brand loyalty here. Judge it on the specification table and the price rather than on sentiment: check the figures that decide your use case, then put it side-by-side with two or three close alternatives in the Compare tool before clicking through.

Common buyer scenarios for accessories of this kind: matching it to an existing build, replacing a failing part, or upgrading from a previous-generation equivalent. Check the spec table below against your current setup — particularly socket / form-factor / power-rating fields — and confirm compatibility on the retailer's listing before purchase. Prices and stock are set by the retailer and may have moved since this page was last updated.

Frequently Asked Questions

Can this card record 4K video without dropping frames?

Yes. It is rated V30, U3, and Class 10, which guarantees a 30MB/s minimum sustained write speed, the standard threshold for 4K UHD recording.

How much storage do you actually get from the 256GB?

Less than 256GB. DIGIERA counts 1GB as 1 billion bytes, and formatting plus device system files reduce it further; a 128GB card typically shows about 115-119GB.

Does it work in a Nintendo Switch, Steam Deck, or other console?

DIGIERA lists gaming consoles among supported devices, and the SDXC format plus A2 rating suits game storage. Check your console's supported card type and capacity first.

What does the A2 rating do for phone and tablet use?

A2 targets random I/O rather than file copies. DIGIERA specs up to 4,000 random read and 2,000 random write IOPS, which speeds app loading and multitasking from the card.

Does it include an SD adapter for cameras and laptops?

Yes, a full-size SD adapter ships in the box, so the same card works in DSLR and mirrorless bodies, laptop SD readers, and other full-size SD slots.

  • High-Speed Performance: Featuring UHS-I bus interface, the DIGIERA microSD card delivers up to 100MB/s read and 70MB/s write speeds, making it perfect for transferring 4K UHD videos, RAW photos, and large files quickly.

  • 256GB Extra-Large Storage: With 256GB of storage space, the DIGIERA memory card holds approximately 48,000 high-resolution photos, 11+ hours of 4K UHD video, or numerous large game files. Due to different capacity algorithms and partial capacity used for system files, management, and performance optimization, the available capacity may be less than the identified capacity
  • Broad Multi-Device Compatibility: Equipped with SDXC technology and an included SD adapter, this mini SD card works with smartphones, tablets, laptops, cameras, drones, gaming consoles, security cameras, and more.

  • Note on Storage Capacity: 1GB = 1 billion bytes. 1TB = 1 trillion bytes. Actual usable storage capacity will be less due to the operating system, formatting, firmware, and device-specific system files. The available capacity on your device will vary based on the host device, operating environment, and file system used. Example: A 128GB memory card will typically show approximately 115-119GB of available storage.
