A hardrive does not affect peformance, its to store data and such, unless you replace the HDD for one with a higher RPM.

If your applications do a lot of disk intensive work, you'll notice a performance increase with RAID 0. For just loading applications, like games, you won't notice much of an increase.

Reverence - did you convert to RAID 0?  I'm expecting a new XPS 600 on Monday.  I ordered it with a single 250GB drive as I already have another recent 250GB SATA drive in my Dimension 8300 which I was hoping to add into the XPS600.

I've downloaded the XPS 600 user guide and it doesn't appear to contain any advice on migrating from a single hard disk to a RAID 0 array.  Will I have to reinstall the operating system before I can get a RAID 0 array up and running?

Hi, Tuff

Ive researched stuff about raid, and basically to get the full performance you need the same kind of hardrive, im not really sure what hardrive will you get but i think you gonna get a seagate SATA w/ NCQ, I've seen the 160GB on ebay and I was thinking of buying it, but i read about RAID and you wont get any performance boost in all programs, it depends on what program you use, i think its better to get a single wdRaptor than getting another one of those seagates to do a raid0, or better yet 2 of those wdraptors, or maybe it depends really on the hardrive, im not a tech-know-it-all person but correct me if im wrong, i just reading stuff.
