HPE 32GB microSD RAID 1 USB Boot Drive

The HPE P21868-B21 is a boot drive that relies on two 32GB microSD cards working in a hardware RAID 1 mirror, all housed in a convenient USB form factor. It offers a straightforward way to keep your operating system isolated from primary data storage on HPE servers, which can help simplify backups, upgrades, and disaster-recovery plans.

Because the unit ships already configured, an administrator can slide it into an available USB slot, power on the server, and see a single, redundant volume ready for installation. If one microSD card ever fails, the mirrored partner keeps the system online, and the faulty card can be replaced without rebuilding the operating system.

An included 2280 M.2 NVMe SSD enables Gen3 PCIe support, so you retain performance headroom while still meeting the physical limitations of tight rack environments. The drive is compliant with USB 2.0, and its small footprint of 2.01 cm by 6.3 cm by 0.94 cm lets you preserve front-bay real estate for application data drives.

This product fits naturally in virtualized hosts running VMware ESXi, Linux distributions, or Windows Server where you want a dedicated, resilient boot device. It also suits branch-office servers or edge systems that must stay up without hands-on intervention. With a one-year limited warranty, 0.4 kg total weight, and compatibility across HPE Compute Mainstream Platforms, it delivers a practical, plug-and-play path to reliable server booting.
