Available in PDF, EPUB and Kindle. Book excerpt: I have implemented a prototype log-structured file system called Sprite LFS; it outperforms current Unix file systems by an order of magnitude for small-file writes and matches or exceeds Unix performance for reads and large writes. Even when the overhead for cleaning is included, Sprite LFS can use 70% of the disk bandwidth for writing. Unix file systems typically can use only 5-10%.
