Twin-card kit for 4K capture

This pack supplies two 128 GB SDXC cards rated UHS-I, V30 and Class 10 for cameras that record 4K UHD video or fire sequential bursts. Each card delivers read speeds up to 200 MB/s and write speeds up to 90 MB/s so the buffer clears quickly between shots. The included slim holder keeps both cards together and protected in a gear bag.

Durability in extreme environments

Cards are tested to survive water immersion, shock impact and X-ray exposure while operating from -13 °F to 185 °F. Solid-state construction means no moving parts to fail, silent operation and no extra power draw beyond the host device. QuickFlow technology sustains the 200 MB/s offload rate when paired with a compatible reader.

Holder and reader synergy

The bundled slim case organises the pair without adding bulk, reducing the chance of lost media on location. SanDisk notes that maximum transfer speeds require the Professional PRO-READER SD and microSD Card Reader, so buyers without that hardware will see lower offload rates. No software utilities are included in the package.

Questions about this item

How do I insert the 128GB SDXC card into my camera and avoid the write-protect mistake?

Slide the card label-side up until it clicks; then check the tiny side switch is pushed toward the contacts so the V30 write speed of up to 90 MB/s stays active.

Will the card or the slim holder need replacement after heavy 4K UHD use?

The cards are water, shock and X-ray proof and rated for -13 to 185 °F, so only the plastic holder might crack if crushed; the silicon itself has no wear-out spec.

What sustained-speed ceiling hits first during long 4K bursts?

The V30 rating guarantees 30 MB/s minimum write; the card can peak at 90 MB/s, but the UHS-I bus and host device usually limit continuous throughput before the card does.
