I've been trying to gather disk speed results for a number of servers using the DiskSpeed utility, but I'm scratching my head at some of the results. The utility returns a list of 'Block Size' results, and I was trying to understand if this relates to 'cluster size' in a Windows system. For example, the cluster size by default on NTFS formatted drives is 4KB, so should I expect my disk speed performance to be inline with the 4KB Block Size results? If this is the case I'm seeing some much different results and I'd like to understand them. Not sure what additional information to include in this email to start with, but if anyone can help point me in the right direction I'd appreciate it.

Thanks,
Troy.

Hi there! Im going to change the scoring on the next release befcause it seems to confusre a lot a people. Basically the block is is the speed its reading chunks of data of that specified size at a time. So if a drive transfers data at 32KB faster tahn other block sizes, its probably the best cluster size for your system or if your building a RAID array, its the best striping block size etc.

The new version will hopefully be a lot simpler to understand!

Cheers!
