Ben, never trust a benchmark, you haven't faked yourself!
There are many benchmarks out there, but the question is, how relevant are they for your usage pattern. How important are single stream benchmarks, when you are opening and closing 1000s of files per second or if you run a DB on top of it. At the end there is only one benchmark, which is the one you wrote yourself which simulates your application. There are some generic ones, like dd or iozone, which gives you a throughput number or some other (bonnie, etc.) , which tests other functions. At the end you need to know what is important for your usage and if you care on numbers like how many snapshots you can do per seconds or not. Writing your own benchmark in perl or a similar scripting language is quickly done and gives you the numbers you need. At the end storage is a complex system and there are many variables between the write() request and the bit being written on a piece of hardware. I wouldn't trust any numbers from syscall/sec benchmarks being relevant in my environment.
