Recently I published benchmarks of Btrfs from a Serial ATA 3.0
SSD (the excellent OCZ Vertex 3 SSD) and those results were interesting,
but most people aren't running 6Gb/s solid-state drives, so how does
this next-generation file-system perform on the opposite end of the
spectrum? In this article are EXT4 and Btrfs benchmarks from an old Core
Duo notebook with a 5400RPM mobile hard drive.
