For Windows gurus

[tmp007]

Hello folks,

I have a scenario where small blocksize write (to SAN Storage and Local Disk) is inffecient whereas large blocksize write is efficient.

I am looking for a tool/utility on WINDOWS which can show the throughput at different blocksize writes. I know I can use "dd" command after using "Cygwin" interface. But I would like to know if there is any direct tool/utility on WINDOWS which can help me here.

Cheers

Sure, you can use the ATTO benchmark:

Generally speaking what you describe is perfectly "normal".

If using Flash based storage, usually very slow on writes and on small "chunks" you may be interested in this thingy here:
