Lexar Professional 1667x SDXC UHS-II Card 256GB - Professional 1667x

UHS-II (Ultra High Speed II) is a newer standard that offers significantly faster data transfer speeds compared to UHS-I. UHS-II utilizes an extra row of pins on the card connector, enabling theoretical speeds up to 312MB/s, while UHS-I is limited to theoretical speeds of 104MB/s. This card supports UHS-II for maximum performance.

V60 is a rating indicating that the card can sustain a minimum write speed of 60 MB/s. This is crucial for recording high-resolution video formats like 4K at higher frame rates without dropped frames or recording interruptions.

Yes, this Lexar Professional 1667x SDXC UHS-II card is backwards compatible. It will work in a UHS-I device, but it will operate at the maximum speeds supported by the UHS-I standard, not its full UHS-II potential.

It is recommended to format the card in the device (camera or camcorder) where it will be primarily used. Most devices have a format option in their menu. Alternatively, you can format it using a card reader on a computer, but ensure you back up any important data first, as formatting erases all content.

The Lexar Professional 1667x SDXC UHS-II card has a maximum read transfer speed of up to 250 MB/s when used with a UHS-II compatible reader and device.

The card offers a write speed of up to 90 MB/s, which is suitable for burst photography and recording high-definition video formats.

Yes, with its V60 rating and high write speeds, this card is well-suited for recording 4K video and other high-resolution video formats.

Ensure the card is fully inserted into the slot. Try cleaning the card's gold contacts with a dry, lint-free cloth. Test the card in a different compatible device or with a different card reader. Format the card using a UHS-II compatible reader if possible (back up data first).

Verify that you are using a UHS-II compatible card reader and that your computer's interface (e.g., USB port) supports the reader's speed. Ensure the card is inserted correctly into the UHS-II designated slot on the reader.

Format the card in the recording device (backup data first). Check for firmware updates for your camera or device. Test with a different card to rule out device issues. If the problem persists, the card may be corrupted or damaged.

Check if the write-protect switch on the SD card adapter (if used) is in the 'lock' position. If not, try formatting the card in a computer. This issue can sometimes indicate card failure.
