I have read anecdotes about people installing RAID0 (RAID - Wikipedia, the free encyclopedia) on some of their machines because it gives a performance boost. Because bandwidth on the motherboard is limited, can someone explain exactly why it should be faster? (7 Replies)

ataraid
ATARAID(4) BSD Kernel Interfaces Manual ATARAID(4)
NAME
ataraid -- software BIOS RAID
SYNOPSIS
pseudo-device ataraid
ld* at ataraid? vendtype ? unit ?
DESCRIPTION
The ataraid driver provides support for BIOS-based software RAID controllers. These are devices which have some simple support for several
basic RAID levels (often RAID 0 and RAID 1), but which require software support to actually perform the RAID function. The BIOS support is
largely just to create and recognize the array so that it may be a boot device.
The driver currently supports RAID formats from:
o Adaptec HostRAID (found in Intel 6300ESB)
o Intel MatrixRAID
o JMicron RAID
o nVidia MediaShield
o Promise FastTrak
o Via V-RAID (found in many VIA-based motherboards)
Status of the logical disk as well as the disks associated with it, can be viewed through the bioctl(8) utility.
SEE ALSO
ld(4), bioctl(8)
HISTORY
The ataraid driver first appeared in NetBSD 2.0.
AUTHORS
The ataraid driver was originally adapted from FreeBSD by Jason Thorpe <thorpej@NetBSD.org>.
BUGS
Not all features of the software RAID are currently recognized or supported. For example, the Adaptec support doesn't recognize when a RAID
1 should be in a ``building'' state, and it does not do the right thing.
At least part of the reason for this is that the publically-available information on these formats is quite limited.
