APPENDIX

RAID 1

RAID 1 is also known as “disk mirroring”; data written on one

disk drive is simultaneously written to another disk drive. Read

performance will be enhanced if the array controller can, in

parallel, access both members of a mirrored pair. During writes,

there will be a minor performance penalty when compared to

writing to a single disk. If one drive fails, all data (and software

applications) are preserved on the other drive. RAID 1 offers

extremely high data reliability, but at the cost of doubling the

required data storage capacity.
