What works. What doesn't.
Speed
Samsung lists up to 1,050MB/s read and 1,000MB/s write over USB 3.2 Gen 2. Apple lists USB 2, up to 480Mb/s, on the iPhone 15, 16, 16e, 17, 17e and Air, so those phones cap the drive near 60MB/s. Pro models and iPhone Duo list USB 3, up to 10Gb/s.
Storage media
A sealed 2TB SSD with no card slot. Samsung ships it formatted exFAT, which is on Apple's list of formats iPhone can read, and says it can be reformatted as APFS.
Power
Samsung says its portable SSDs run on as little as 2.5W (5V at 0.5A), and that the T7 stays under the 4.5W limit Apple sets for ProRes recording at room temperature (25C). It recommends the cable that comes in the box.
