The Lexar Professional 633x SD card, announced at CES earlier today, is the largest capacity SD card available to date at a whopping 1 TB. Despite its large size, the card is somewhat disappointing in performance; the 633x is rated at 95 MB/s write and 70 MB/s read. It also supports VSC Class 30, which means it should hit at least 30 MB/s when recording video. This should be adequate for 4K footage, but higher bitrates and higher resolutions may suffer.

Photographers and videographers that constantly swap SD cards throughout busy workday may be in luck. Lexar announced the world’s first commercially available 1 TB SD card at CES earlier today.

The Professional 633x SDHC/SDXC card is now available in a 1 TB size, the largest SD card available to consumers yet. The card is marketed at professionals, specifically videographers, due to its massive storage capacity. To put it in context, the 1 TB SD card should hold somewhere between 30-35 total hours of 4K video footage, depending on bitrate and framerate.

Despite its large size, videographers may find the card a bit limiting, especially for recording at 4K or higher. The Professional 633x SD card’s performance is rated at up to 95 MB/s read and 70 MB/s write. The Video Speed Class (VSC) is rated at 30 MB/s write, which may be a bottleneck for high bitrate, high framerate video.

Still, there currently isn’t a competitor card that can match the Lexar Professional 633x in sheer storage capacity. Lexar knows this and has set the price to be rather high at US $500. The card should become available at retailers in the coming weeks.
