Dell Datasafe / RAID 1 / Ghost questions

I just got the Dimension 5150 wth datasafe that I ordered recently and have few questions.  Can anyone take a shot at this / confrm my thinking?  

1) So is there any documentation about this!?

2) From opening the box and watching the boot process,  I see there's 2 - 160 gb drives in a hardware RAID 1 configuration (mirroring of the 2 drives - everything on drive A is also on drive b - protects against drive a or b failing).  all that right?

3) so does the 5150 come with hardware raid standard, even if you don't order datasafe? Or is there differences in the motherboard / bios that enables raid on the machines you pay for it?

4) You've got 4 partitions on the drive according to drive manager - a dell utility partition, the C drive, the D drive (which is where ghost stores snapshots) and another partition that holds the restore of the original drive (so they don't have to send the restore CD).  All that right?

5) So the ghost part of this is just to take the snapshots?  how does this differ / improve on windows system restore, which I've never used.

thanks!

Dell DataSafe: A Brief Explanation


Dell DataSafe is a solution that helps protect data from destructive events such as system crashes, hard drive failures, viruses, and software corruption. Based on the solution selected, you can configure the computer to automatically store periodic copies of your data to protected areas of your hard drive array.
Not only does Dell DataSafe allow you to store and protect valuable data such as photos, music, videos, files, and more, it also helps restore the system and data in the event of a failure. The included Symantec software provides the ability to roll back the system to a healthy state, easily retrieve deleted files, and recover individual files or the entire hard drive.

Dell DataSafe uses Symantec Ghost software and RAID 1 (mirror) technology to create a robust level of data protection for your files.
 
 
What are the benefits of having Dell™ DataSafe on my system?


 
Even though today’s PCs are very reliable devices, there is still a risk that potential issues could occur. Threats such as viruses, corrupted software and possible hardware failure magnify the need for a simple, automatic and reliable data protection solution. DataSafe provides the following:
Gives you an affordable backup solution for your data
Combines hardware and software backup options to give a superior level of data protection
Is a totally internal solution for the desktop (no external hard drives needed)
Serves as protection from software and hardware failure (viruses; hard drive crashes)
 
 
A protected hidden hard drive is built into your system. In the event of an actual hard drive hardware failure, your system can keep functioning normally allowing you to replace the failed hard drive at your leisure.
Your primary hard drive has also been partitioned to allow for storage of your hard drive images so that you don’t need an external hard drive to store your backed-up data. You will notice a partition (hard drive) named Data Backup within the My Computer icon. This allows you to recover your hard drive data or selected files in the event of a software failure incident (Figure 1).

I know the official pitch about it....

But:

3) so does the 5150 come with hardware raid standard, even if you don't order datasafe? Or is there differences in the motherboard / bios that enables raid on the machines you pay for it?

4) You've got 4 partitions on the drive according to drive manager - a dell utility partition, the C drive, the D drive (which is where ghost stores snapshots) and another partition that holds the restore of the original drive (so they don't have to send the restore CD).  All that right?

5) So the ghost part of this is just to take the snapshots?  how does this differ / improve on windows system restore, which I've never used.

3)  Yes, the 5150 uses the Intel RAID included on the mobo.
4) Yes
5) Correct. System restore just takes note of critical files, and allows you turn back any changes made to system files/registery. The data safe takes a whole snapshot of all files, and put all files back onto the HDD(vs. just correcting a few sys files). This is better because it is a complete backup of all files on system, and allows for almost instaneous repair of the OS
