For : removing RAID 0 is doable, but the most important step is protecting the data on that striped volume. raised the performance tradeoff and flagged the installation/recovery issue — below are practical, low-risk options and concrete steps to follow so nothing important is lost.

Start checklist (do these before touching the array)

  • Make a complete backup of everything on the machine to external media. A file copy is good; a full image is best if you want an exact system restore.
  • Make or obtain Windows install/recovery media and any driver CDs you might need.
  • Note product keys, activation info and any hidden recovery partitions (manufacturers sometimes use these instead of recovery CDs).

Two common ways to remove RAID 0

  • Fresh reinstall to single disk: After backups, use the RAID configuration utility at boot to remove the array (this destroys the logical volume). Change SATA/IDE mode in BIOS if you prefer non-RAID operation, boot from install media, repartition and install Windows on a single drive, then restore files from backup.
  • Clone the RAID volume to a single drive: Use a disk-imaging/cloning tool (for example, bootable rescue media from current imaging tools) to image the RAID volume to external media, then restore that image onto a single target drive that is large enough. Test that the new drive boots before wiping the originals.

Troubleshooting and cautions

  • If Windows refuses to boot after switching SATA mode, a driver mismatch is usually the cause; repair/install via install media or revert the BIOS setting until drivers are prepared.
  • If there is no backup and the array is the only copy, avoid deleting the array — data recovery from RAID 0 is complex and often expensive.
  • If the goal is reliability rather than speed, consider migrating to RAID 1 or using regular image backups.

If unsure about any step, get Dell support or a local technician to do the migration so the array and your data are handled safely.

Any reason you want to remove the striping? Its benifitial to the computer overall

It should be available to change in the bios, check your manual. The only issue I can see is that when you remove the RAID 0, you will have two hard drives with little bits and pieces of your data and operating system on them (assuming your OS is installed on them). These drives are now useless and must be re-formatted. Sometimes companies don't ship their computers with full versions of the OS. Even scarier is that sometimes the OS disk is written as an image to the hard drive (this saves the company money because they don't have to make CDs). If these are your only two drives, you will want to make sure that you'll be able to install the OS.

Oh, and I can understand why you'd want to remove RAID 0. I've heard that it only gives you about a 30% increase in efficiency for most applications, and it doubles your risk of data loss.
