What does Raid 0 "Stripe" means when they are referring to hard disks?

I am thinking of buying a Dell system with 3 TB HD and 12,288 MB DDR3 RAM
but I want to confirm with you guys that it simply means two disks and it
can be used in the normal way like at present - Master/Slave
configurations.

Thanks.


Basically in your case a 3 TB HDD RAID 0 setup is two 1.5 TB drives tied
together to create one 3 TB drive letter. Part of the data in a file is
written to one drive and part is written to the second drive to increase
speed of the write and read process (data can travel down the pipe faster
than the pump can supply it so they put in two pumps (drives).) The main
issue with RAID 0 is that there is no automatic data backup. If one drive
fails all the data on both drives is unrecoverable (unless you have a backup
off of the RAID system.

From Wikipedia: "A RAID 0 (also known as a stripe set or striped volume)
splits data evenly across two or more disks (striped) with no parity
information for redundancy. RAID 0 was not one of the original RAID levels
and provides no data redundancy. RAID 0 is normally used to increase
performance, although it can also be used as a way to create a small number
of large virtual disks out of a large number of small physical ones."

What you probably CAN NOT do in this case is use the built in recovery media
(and the disks that you can create) to split the drives into two 1.5 TB
drives to use in the way you mentioned as the OS will have the RAID drivers
and setup already done to recreate the original setup. Personally I would
ask Dell if you can order the system without the drives combined into a RAID
configuration.
