Quantcast Open Sources Hadoop Distributed File System Alternative

Feldman says internal benchmarks found that QFS reads are up to 75% at faster than HDFS and writes up to 46% faster. QFS uses a more efficient data replication system based on Reed-Solomon coding so that data takes up less disk space — this also reduces the overall IO required. And QFS uses C++, which has a few performance benefits over Java as well.
