Compiled this simple testprogram for random access read benchmark. http://www.linuxinsight.com/how_fast_is_your_disk.html

Howto run on dns323

Those are some interesting numbers - I'd love to see some from the same disk in & out of the DNS-323 - perhaps see what impact the DNS-323 has on the test results.

I don't know if you've ever noticed but the read/write performance absolutely sucks when you're dealing with multiple small files - for example - backing up a few thousand <100 kByte files that would typically make up web pages - which I think would qualify as "random access".
