"The drive comes in 128 GB ($30 list price) or 256 GB capacity ($55) and plugs into any USB Type-A port, though it works best when attached to one that operates at USB 3 (aka USB 3.1 Gen 1 and USB 3.2 Gen 1) speeds of up to 5 Gbps. The snazzy-looking stick boasts an all-aluminum chassis with a Raspberry Pi logo on it and a hole you can use to attach it to a keyring."
"According to Raspberry Pi, the cache allows the drive to "be almost as fast as USB 3.0 can go" in sequential writes, but when a workload saturates the cache and it has to write straight to the QLC, the drive operates at speeds of 75 MB/s (128 GB capacity) and 150 MB/s (256 GB capacity). The company does not tout a sequential read speed but estimates random read and write speeds in terms of IOPS (Input / Output Operations per second) at a 4K block size."
Raspberry Pi sells a USB Type-A flash drive in 128 GB ($30) and 256 GB ($55) capacities with an all-aluminum chassis and a keyring hole. The drive performs best on USB 3 (up to 5 Gbps) ports and can function as general storage or a boot drive for Raspberry Pi systems. A pseudo-SLC cache converts portions of QLC NAND into single-bit mode to boost burst performance. When the cache is exhausted, sequential write speeds fall to 75 MB/s (128 GB) and 150 MB/s (256 GB). Random 4K IOPS are rated at 16,000/21,000 (128 GB) and 18,000/22,000 (256 GB). The drives should outperform microSD cards when used as boot media on Raspberry Pi 4 or 5.
