From a JB post...

Ok. If your computer is a brand name, lets say Dell or HP, they have a support on there site and driver downloads. They also have online scanners. However, if you find your motherboard's manufacturer make and model, etc., then you can search from the menu's website for the BIOS update. Some BIOS updates need to be put to floppy first, some can be downloaded and straight install. A reboot is required.


RAID 0
RAID 0 provides data stripping – it takes data that needs to be stored and distributes it evenly between two or more hard drives. Because the system considers the two hard drives as one logical hard drive, the data is stored only once.

In a two-drive setup, for example, RAID 0 saves and accesses data quickly and efficiently. Rather than one bit at a time, RAID 0 stores and retrieves two bits of data simultaneously. Theoretically, the time it takes to save and access information is cut in half over a single drive system.

RAID 0 is popular for video and image production and editing, pre-press applications, and other applications requiring high bandwidth. However, RAID 0 does not provide fault tolerance – if one drive fails, the information on it is lost.

RAID 1
RAID 1 provides “disk mirroring,” which copies the same data onto two or more drives. Unless the system uses RAID 1 with duplexing, both drives must use the same adapter card.

Unlike RAID 0, RAID 1 allows for fault tolerance. Since the same data is saved twice, if one hard drive fails the second has a complete copy of all information saved. While not as fast as RAID 0, RAID 1 retrieves data more efficiently than a single drive setup because information is gathered in from more than one location.

RAID 1 is popular for accounting, payroll, financial, and other applications that require high availability and higher relative data security. However, RAID 1 writes data once in each drive, which makes saving data less efficient and halves drive capacity.
