Hi, Saqib. Thanks a lot for your answer; don't worry about "late"; what matters is to get a response at all.
I wanted to ask you if you could give a bit more information on the specific utility you used (name, who makes it, etc.). I work for a security software development company and we have good relationship with hardware/software vendors, so it's quite likely our devs. know the tool. Apart from that, I wanted to ask about the specs of the computer(s) used in the test. I'd like to do some benchmarking of our own products, to see if the impact we have is consistent with that of other products out there; for that, I'd need to set up a similar system. I know that what I should really do is try to get my hands on the products myself, and do a real benchmark, but at the moment I don't think I can get the resources needed for that, so I'll have to settle for a "rough" benchmark and see what it turns out. We've been taking some measurements using HDTACH (http://www.simplisoftware.com/Public/index.php?request=HdTach) and now I've stumbled on IOMeter (http://www.iometer.org/, "Iometer is an I/O subsystem measurement and characterization tool for single and clustered systems"), a project that Intel begun and that now is Open Source, and it looks interesting, as it lets you simulate different workloads. I really believe it'd be interesting to try to do some benchmarking with a setup that others might replicate, so the results are more meaningfull for everybody. Just my 0,002 Thanks a lot in advance Javier Jarava -----Mensaje original----- De: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] En nombre de Saqib Ali Enviado el: martes, 23 de enero de 2007 17:49 Para: [email protected] Asunto: Re: [FDE] FDE Impact analysis: Tools / method used to get thenumbers? Hello Javier, Sorry for the late response. I used a File Access Timer utility. This utility is for limited distribution to only disk management software (e.g. defrag) vendors. It can read a complete file, and you can define the block size. It produces excellent stats. However I think one could write this utility in C. It shouldn't be that complex. If you going to perform the test, please try with smaller file sizes. That would be interesting.
