How it makes file storage cheaper
Because RAID 0 lets your notebook see multiple hard drives as 
a single drive, you can install two lower capacity (less 
expensive) drives and have the same single-drive storage 
simplicity and capacity as a larger, more expensive hard drive.
Drawbacks
Unfortunately, RAID 0 lets two drives behave as one in another 
way. If part of the array fails (such as a hard drive crashing), 
the entire array fails. Because the drives are treated like a single 
drive, parts of files (including operating system files) can be 
spread across both drives, leaving the notebook with only file 
fragments if one drive fails. Regular and frequent backups are 
critical.
Another drawback is that RAID 0 treats each hard drive as if it 
has the storage capacity of the smallest drive in the array. So 
if you have two drives (300 GB and 200 GB) in a RAID 0 array, 
your notebook only recognizes 400 GB total capacity.
RAID 1 for security
RAID 1 maintains a complete copy of all files on each physical 
hard drive in the array. Maintaining simultaneous, complete 
copies of files across both hard drives is called mirroring. If a 
drive fails, the mirrored drive takes over and acts as the 
primary drive.
In the graphic below, each letter represents a unique block of 
data, and each column represents a separate hard drive.
File reading performance (seek time) is increased using the 
same methods that RAID 0 uses, although writing speed is the 
same as if writing to a single hard drive.

Drawback
RAID 1 treats the entire array as a single drive with the storage 
capacity of the smallest physical drive in the array. So if you 
have two drives (300 GB and 250 GB) in a RAID 1 array, your 
notebook only recognizes a single drive with 250 GB total 
capacity.
Preparing your notebook for RAID
Setting up RAID on your notebook can involve two major steps, 
depending on how your notebook has been configured.
To prepare your notebook for RAID:  
1Configure the RAID arrays. See the Array Manager User 
Guide, or “Configuring RAID” on page 54.
2Install the operating system.
Configuring RAID
Enabling RAID
If you ordered your notebook with a RAID configuration from 
the factory, RAID is already enabled, and you can skip this 
procedure. However, if your notebook came without a RAID 
configuration and you set up RAID yourself, you must enable 
RAID before your notebook can use it.
To enable RAID on your notebook:  
1Start (or restart) your notebook.
2As soon as your notebook turns on and the Gateway logo 
appears on the screen, press F2. The BIOS Setup utility 
opens.
3Select the Advanced menu, then select SATA mode.
4Change the SATA mode to RAID.
5Press F10, then type Y to exit BIOS saving changes.
Now that RAID is enabled, you can access the RAID setup.
Creating a RAID volume
Because RAID can be configured so many ways, this procedure 
covers only the basics.

Resetting drives to non-RAID status
To troubleshoot or repair incompatible RAID configurations, 
failed RAID volumes, or failed drives within a RAID volume, you 
can reset (remove from the RAID) the drives until the problems 
can be resolved.Caution
If your notebook has the operating system installed on a RAID, 
deleting the RAID will remove the operating system, and you will not be 
able to start your notebook.

and eSATA (external SATA hard drive). You use these ports to 
connect peripheral devices such as printers, scanners, and 
digital cameras to your notebook.
USB ports support plug-and-play and hot swapping, which 
means that your notebook will usually recognize such a device 
whenever you plug it into the appropriate port. When you use 
a USB device for the first time, your notebook will prompt you 
to install any software the device needs. After doing this, you 
can disconnect and reconnect the device at any time.Important
