Two 128GB SDXC cards in a single pack

This kit contains two SanDisk SDXC cards, each rated at 128GB and Class 10 speed. They are full-size Secure Digital cards built for devices that accept the SDXC standard. The pair is ready for immediate use in compatible cameras, recorders or other portable electronics.

Suits shooters who need a spare card on hand

Photographers and videographers who want a backup card in the same bag will find this twin pack convenient. Users whose hardware only supports the older SDHC standard should check compatibility first, because these cards require an SDXC-capable host.

Class 10 speed rating defines minimum write

The Class 10 marking guarantees a minimum sustained write speed of 10MB/s, which is the key figure for deciding whether the card can keep up with your recording bitrate. If your workflow demands a higher guaranteed minimum, these cards will not meet that requirement.

Questions about this item

Will these Class 10 SDXC cards work in an older camera that only supports standard SDHC?

The cards follow the SDXC specification, which is a different capacity range from SDHC; check your camera manual to confirm it accepts SDXC media before use.

How can I verify the cards are delivering Class 10 performance after formatting?

Run a sustained write test with a benchmark tool; a steady minimum write speed of 10 MB/s confirms the Class 10 rating is being met.

Does the twin-pack include any adapters or cases, or must I buy them separately?

The kit contains only the two 128GB full-size SD cards; microSD adapters, USB readers and protective cases are sold separately.
