There are many benchmarks on file systems that are available. For example: Ext3 vs ReiserFS

My advice to you: Take a look at the Linux kernel. It has many drivers on how file systems are designed and made. Also with Linux, you do have the ability to simulate a file system by using a loop back (a file system mounted in a file).

Another option that you have is that if you are going to create a partition on a raw disk, you may want to develop that within a virtual machine, so that you do no have to have to buy new equipment or cause damage to your development machine.

As I said here, I really recommand the journal paper by Brook University and IBM Watson Labs in the "Transaction of Storage" about file system benchmarking, in which they present different benchmarks and their strong and weak points: A nine year study of file system and storage benchmarking: A nine year study of file system and storage benchmarking.

They give lots of advise how to benchmark a filesystem benchmark. It is not an easy task to do it right.

I would say: It is better with multiple disks and multiple machines otherwise I as reviewer would probably have doubt about your evaluation. I really know the problem: I myself have only a few nodes and a few dozen disks available for my research. There are disk simulators, e.g. DiskSim, that maybe can be used for fake disks, but in a distributed setting you probably have to fake the other components (networking, locking, too). It maybe isn t impossible -- simulations are often used on other distributed settings, e.g. sensor networks -- but it is hard to do it in a rigorous way.

Edited: Related to books: There isn t any really good book, but here is a short list:

• UNIX Filesystems: Evolution, Design and Implementation (2003): Older book and not really good, but on of the best I am aware of.
• Practical Filesystem Design (1999): Gives a nice overview about filesystem design in the 90s. I covers the BeOS filesystem in depth. But both books cover only single node filesystems.

A lot of storage courses at storage research labs recommend NFS Illustrated (2000).

P.S. And please! Stop moving everything to serverfault where the title contains "file systems"!

You can perform benchmark tests using a tool like IOZone. Performance benchmarks only tell part of the story, though. Do you need journaling, replication, etc? You might get worse performace in a benchmark but have additional features that are essential to your needs. Wikipedia has a decent comparison of some filesystem features.
