"Want to connect a lot of drives to your Pi? You need the $15 that has four downstream USB 3.0 Type-A ports, offers data transfer speeds up to 5 Gb/s, and can draw up to 4.5W of power from the host Raspberry Pi, or it can make use of an optional USB-C power input, which increases the power to 15W."
"The drives are encased in an all-aluminum shell that is both tough and acts as a heatsink to dissipate excess heat, and have a hole on the end for a lanyard. Performance is dependent on capacity: 128GB capacity 16k IOPS (4kB random reads) 21k IOPS (4kB random writes) 75MB/s sequential write speed (sustained) 256GB capacity 18k IOPS (4kB random reads) 22k IOPS (4kB random writes) 150MB/s sequential write speed (sustained)"
The Raspberry Pi Foundation offers a compact flash drive accessory that plugs into Raspberry Pi USB-A ports and comes in 128GB and 256GB capacities. The drives support SMART and the TRIM command for failure monitoring and improved longevity. They use a USB 3.0 Gen 1x1 Type-A interface while remaining backward compatible with USB 2.0. The aluminum shell provides toughness and acts as a heatsink and includes a lanyard hole. Performance varies by capacity, with the 256GB model delivering higher IOPS and significantly faster sustained sequential write speeds. The drive can also function as a regular USB flash drive.
