The 250GB and 1TB Expansion Cards give you the performance of an internal drive with the flexibility of an external one. With a USB 3.2 Gen 2 interface, the 1TB card exceeds 1000 MB/s read and write speeds, while the 250GB card reaches 1000 MB/s read and 375 MB/s write speeds. Both are fast enough to run apps and even boot an operating system from, and you can plug them into other computers for high-speed file transfer.
