SPDK is a set of C libraries, drivers, and tools for building high-performance, scalable user-mode storage applications. It moves storage drivers (NVMe, I/OAT, Virtio) into userspace with polled-mode, thread-per-core, lockless designs to eliminate kernel context switches and interrupt overhead.
Use cases
- build a high-performance NVMe driver in userspace
- run an NVMe over Fabrics target
- run an iSCSI target in userspace
- expose virtual disks to VMs with vhost
- benchmark and tune storage I/O performance
- write custom block device modules
- implement a user-mode storage application with polled-mode I/O
When to choose
- you need maximum storage I/O performance with minimal latency
- you are building NVMe-oF, iSCSI, or vhost targets
- you want user-space NVMe drivers with a thread-per-core architecture
- you need a production-proven, well-documented storage development kit
When to avoid
- you only need simple file or block I/O without extreme performance requirements
- your platform is not Linux or FreeBSD
- you cannot dedicate CPU cores to polling
- you need a portable cross-platform storage library
