Looking for disk I/O bench marks?

[qnerd]

I am building a new system and am interested in top end disk I/O. I have seen several benchmarks on this site but they do not break out the disk I/O component. I would like detail down to the level of transfer rates for ATA 100 No Raid, Raid 0, Raid 1, and Raid 0+1. Any idea where I might find this type of benchmarks?

Thanks,

Qnerd

<A HREF="http://www.storagereview.com" target="_new">http://www.storagereview.com</A> has benchmarked a lot of high-end drives but I don't think they have tested RAID systems only individual drives, IDE and SCSI. (Check out their online database).

Perhaps some of their links will lead you to the information you seek.

The site reccomended earlier has an intersting review of two ATA RAID contollers, Promise & 3ware (Promise got smoked completely). Looks like a pretty good site.


In theory, there is no difference between theory and practice.
In practice, there is.

one of the best disk benchmarks is windows magazines'
is does sustained both cached and non cached..

IDE RAID is a waste of time... they do not support multiple concurrent ques like scsi drives, and are not designed to operate cohesively stacking commands like scsi raid

that said RAID 0 is the only fast performance way,
raid 1 is mirrored and therefor slower as it has to double everything..
also IDE in mirror cannot operate concurrantly as they both rely on host CPU and chipset, where scsi drives make better
raid 1-5 as tehy operate concurrently and independly with less overhead

hope that helps
