SFSmark

SFSmark is a term used in the field of computer storage and filesystems to describe a class of benchmarking tests and performance indicators rather than a single, standardized benchmark. Because there is no universal definition, the exact meaning of SFSmark can vary between publications, vendors, and research groups.

In practice, SFSmark studies are employed to compare the performance of storage solutions, including hard drives, solid-state drives, NVMe devices, and distributed or networked file systems. They commonly aim to measure throughput, latency, and input/output operations per second under representative workloads.

Typical metrics include sequential read/write throughput (MB/s), random IOPS, read and write latency, and sometimes throughput under mixed or metadata-intensive workloads. Workloads can be synthetic or trace-based and may simulate common file-system tasks such as creating, reading, writing, and deleting files and directories, as well as metadata operations.

Variants and scope: Some SFSmark implementations target POSIX-compliant file systems, others focus on object storage layers or distributed storage stacks. Results depend on hardware, operating system, cache policies, and the file system in use, so comparable results require carefully documented test configurations.

Notes: SFSmark is not a single standard; users should examine the benchmark's methodology, workload mix, and hardware setup to interpret results reliably.
