◆Raspberry Pi SD Cards
The single-board computer Raspberry Pi uses SD cards for storage, so the official Raspberry Pi statement states that 'the SD card you use makes a big difference in your Raspberry Pi experience.' Until now, Raspberry Pi has worked with certified resellers to test and recommend third-party SD cards, but with the emergence of SD cards that support the A2 standard, which allows for high-speed reading and writing, this process has become increasingly cumbersome.
Therefore, in order to achieve the best experience at the lowest possible cost, Raspberry Pi has collaborated with Longsys to develop its own branded SD card, 'Raspberry Pi SD Cards'. Since Raspberry Pi SD Cards are A2 compatible, they not only provide excellent read and write performance on all Raspberry Pis, but also enable even higher performance on the Raspberry Pi 5 by using command queuing (CQ).
To achieve the best performance from A2-enabled Raspberry Pi SD Cards on the Raspberry Pi 5, you will need to update to the latest version of Raspberry Pi OS and explicitly put the SD card into CQ mode. CQ allows the flash controller to hide the latency associated with accessing different NAND flash pages, theoretically allowing better throughput for random I/O workloads of the kind generated by the Raspberry Pi OS.
In addition, the random 4KB read performance of Raspberry Pi SD Cards is 3200 IOPS for Raspberry Pi 4 and 5000 IOPS for Raspberry Pi 5, and the random 4KB write performance is 1200 IOPS for Raspberry Pi 4 and 2000 IOPS for Raspberry Pi 5. Storage capacities of 32GB, 64GB, and 128GB are available.

◆Raspberry Pi Bumper for Raspberry Pi 5
Additionally, the Raspberry Pi Bumper is now available for the Raspberry Pi 5. It has a snap-on silicone base that neatly protects the base, edges, and surface of the Raspberry Pi 5, and makes the power button easier to use. The Raspberry Pi Bumper is compatible with the Raspberry Pi Active Cooler and costs just $3.
