4TB SD cards are arriving in 2025 for your cameras and laptops

This new SD card will support 8K video recording.

While Western Digital is previewing its four-terabyte SD card at the NAB Show this week, it won’t actually be available until 2025. AnandTech notes that the card uses the Ultra High Speed-I (UHS-I) interface, which supports up to 104MB/s data transfers in the UHS104 (SDR104) mode. It’s taken quite some time to get to the 4TB point, and Western Digital isn’t disclosing what type of NAND is inside the upcoming card, so even higher capacities are likely a ways off.
