Btrfs File-System For Old Computers?

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.

This testing is just like the earlier Btrfs SATA 3.0 benchmarks, but with more Btrfs mount options being tested and with old hardware being used. In particular, a Lenovo ThinkPad T60 was used with a 1.86GHz Core Duo T2400 CPU with 1GB of RAM and a Hitachi HTS541080G9SA00 HDD. The Hitachi hard drive spins at 5400RPM, complies with SATA 1.0, has 8MB of cache, and has a 12ms average seek time. Full system details are below.
