256 GB microSDXC card for Android devices

The SanDisk Ultra Go microSDXC 256GB card adds storage to Android smartphones, tablets and digital cameras. It uses UHS-I interface with A1, C10 and V10 ratings for app loading and Full HD video capture. Read speeds reach up to 190MB/s for quick file transfers. The card is new and built with NAND flash for durability.

Suits phones and cameras needing expandable space

This card fits users who want more room for photos, videos, games and apps on compatible Android devices. It is not for hardware that requires UHS-II or higher speed classes. It is not for buyers who need capacities beyond 256 GB on a single card. It is not for devices limited to microSDHC maximums.

UHS-I A1 C10 V10 speed class rating

The UHS-I A1 C10 V10 rating determines whether the card meets a device's minimum write-speed requirement for apps and Full HD recording. Check the host specification for this exact class before purchase. The 190 MB/s read figure applies to 128 GB to 1.5 TB models including this 256 GB version.

Questions about this item

How do I install the SanDisk Ultra Go microSDXC 256GB card in my Android phone and what step do people often miss?

Power off the phone, open the SIM tray or dedicated slot, insert the card with the gold contacts facing down until it clicks, then power on and format it as internal or portable storage in Settings — skipping the format step leaves the card unreadable.

What maintenance or replacement will this 256GB microSDXC card need over time?

No scheduled maintenance is required; the NAND flash is built for long-term durability, but if write cycles eventually exceed the cell endurance the card must be replaced — there are no user-serviceable parts.

What limit appears first when I keep writing large files to this 190MB/s UHS-I card?

Sustained write speed is capped by the UHS-I bus and V10 rating, so after the SLC cache fills the card drops to a minimum of 10 MB/s sequential write.
