I think velocirpator is best for normal use, and less lous than a RAID0

A comparison or the two variable partitions used and overall performance in RAID0.
Same pair of high end HDDS of say 750G or 1 TB HDDs. Test with the full drive space, test with only a 50G partition.
Of course the RAID controller will likely come into play though. So without a high end RAID card the results could be skewed.
Just a curiosity since I have none of the above items to perform this.

Testing full drive space will give you the information about the 50GB partition. Since hard drives begin at the outer edge and move inwards, so do arrays. An array benchmark will provide you with the info about the first 50GB. If you do a test on the first 50GB partition, the resulting chart will just be an excerpt from the full array.




HOWEVER, if you do an application/real-world test... performance may differ since these tests have more random access involved. The smaller partition may improve these types of benchmarks.
Once again...

Can you or someone clarify how partitions benefit or hamper performance of an HD? Or provide a link of some sort. I am thinking about getting two 160GB WD and putting them in RAID0. At $40 each, you CAN'T beat the value!

BTW, my 7200.1 320GB in RAID0 was fast as all hell! I had three partitions, maybe that had something to do with the performance, but it was very quick. I am super unhappy with RAID1. TOO SLOW.

I DO!!

I've been enjoying them for over a year now. Since the new 7200.11's are out, I'm sure they've dropped in price a little.

I am deathly afraid of even attempting it. I just backed up all my work files and completely filled up a 1TB drive. I'm not sure if all my personal stuff will fit on my other 250gb backup drive. Once backed up, maybe, just maybe I could be convinced to repartition my 2x320gb RAID0 setup. I'm happy with the speed as it is and I'm not sure what kind of performance gain I'll get.
