Professional 1TB UHS-II card

The Lexar Professional 1800x SDXC card delivers 1TB capacity with UHS-II Class 10 performance for DSLR and mirrorless cameras. It reaches up to 270 MB/s read and up to 180 MB/s write speeds for high-resolution photos and 4K video capture.

Sustained write reliability

A Video Speed Class 60 rating guarantees minimum sustained write performance for continuous 4K recording without dropped frames. The card operates reliably from 0 °C to 70 °C and survives storage between -25 °C and 85 °C.

Upgrade from slower SD cards

Photographers moving from UHS-I or lower speed-class cards gain faster burst clearing and quicker offloads. The jump is worth it when workflow bottlenecks appear during long shoots or large batch transfers.

Questions about this item

Does the Lexar Professional 1800x SDXC card run hot during long 4K video sessions?

The card is rated for continuous operation between 0 °C and 70 °C, so it handles sustained write loads without overheating in normal ambient conditions.

My camera only has a single UHS-I slot — will this UHS-II card still record 4K reliably?

It will work in a UHS-I slot but speeds drop to the UHS-I bus limit; you need a camera with a UHS-II slot to reach the 180 MB/s write speed required for smooth 4K capture.

Can I offload footage directly to my older laptop that only has a USB 3.0 Type-A port?

Yes, use a UHS-II compatible USB 3.0 card reader; the card itself has no USB interface, so the reader determines the transfer speed you actually see.
