Windows Vista SP2 Beta vs Vista SP1:Battle of the Service Packs

HD Tune Pro File Benchmark

This file benchmark measures the performance for reading and writing files to the selected hard disk partition with different block sizes ranging from 0.5 KB to 8192 KB (x-axis). The length of the test files can be set. For accurate results a large size is recommended. If the file length is too small, the hard disk may be able to cache the entire file. In that case the cache speed will be measured instead of the hard disk throughput.

Windows Vista SP1

Windows Vista SP2 Beta

Here is where Vista SP2 Beta shows performance improvements. The read and write speeds of the file are higher than Vista SP1 in most of the  block sizes. The read and write speeds for 16KB blocks is increased by about 25MB/s on Vista SP2 Beta.

Lets move on to our next benchmark.
