A friend of mine is looking at buying the following:
[I]Dell XPS 8300: Intel Core i7-2600 (3.40GHz), 16GB (4x4096) 1333MHz DDR3 Dual Channel, 2TB Dual Hard Drive Raid 0 "Stripe" (2x1TB - 7200RPM), 1 GB ATI Radeon HD 5670 Graphics Card, 6X Blu-Ray ROM Combo (Blu-Ray read only, DVD, CD read & write) Drive...[/I]

I see the RAID config is 2TB Dual Hard Drive Raid 0 "Stripe" (2x1TB - 7200RPM)

My first question is where does the Windows OS sit? On a seperate partition? Across both HDD's? or on one HDD and data then stored across the two disks? I tried reading up on RAID 0 but couldn't find any info on the OS

Second question is..if for some reason I was to add a third HDD(2GB) to this config, how does this affect the setup? Does the RAID config need to be altered or can I just add it as 'non-RAID' drive/as it's own partition?
 
For the RAID configuration, the whole hard drive would be put in RAID, so the OS & DATA partitions would both be spread across both drives.

Unfortunately you won't be able to just add another drive to the RAID 0 configuration without formatting all the drives.
AFAIK, there aren't any hardware RAID configurations (except for RAID 1, in which all the drives are just clones) where you can just add another drive without formatting all the drives.

I really think that your friend can build a faster rig for much cheaper than that Dell XPS rig, which has a very entry level graphics card and no SSD.
 
Windows cannot boot from Raid 0 or Raid 5 so he'll need to have his OS running on either a simple volume or a Raid 1 configuration along side the Raid 0 config for data. (And yes you can have multiple raid types in one system, the additional drive won't be part of the current RAID configuration unless you destroy and recreate the RAID while including it - obviously resulting in massive data loss)

Ah silly me. I actually only have RAID experience in Server software/enviroments and after re-examining my notes they only mention that Server 2008 cannot boot from RAID 0. Though I find it strange that the client oses would have more RAID functionality, I'm not scared to admit Microsoft are prone to making...............................odd.............choices.

Basjohn: you should be able to run Windows XP/Vista/7 from a RAID 0 configuration, but you're going to need the RAID drivers - just like Windows XP required SATA drivers for installing it onto a SATA drive if the SATA controller was set to AHCI.

I really dont see this as an odd choice, why double the potential of drive failure in a server environment by enabling RAID 0? Can you imagine the screaming and yelling if people could do this then lose their entire server because 1 drive died? There would be be screams that MS hasn't got a cooking clue about how to configure or build a reliable server environment ;) Just being devils advocate here

Yeah - I'd be worried running RAID0 on the lappie too . A better choice would be to have ssd drive in one slot ( for OS and programs ) and 1Tb hdd in other slot for storage space .
 
RAID0 should be used with caution - if one drive fails you'll lose everything.

Everything.

Rather use RAID1, RAID5 or Z-RAID...


Or an external CF/HDD for backups.

Because Mr Murphy.

+1 to what The_Librarian has to say .

I suppose it's a good option to have a lappie that is capable of taking 2 drives , but not with striping ( RAID0 ) .
