Food Demo:
- Cheese - one of bacteria's greatest gifts to civilization
RAID Definitions:
- - Redundant Array of Inexpensive Disks
- - Redundant Array of Independent Disks
SCSI:
- Small Computer System Interface
- Fast
- Expensive
- High Performance
- Mainly used in Business Situations
RAID:
- RAID 0
- RAID 1
- RAID 0+1 (we used 1TB LaCie F800)
- strips hard drives for capacity and performance, then mirrors them on other drives
- RAID 5
- Can be external or internal technology
- Found on most new motherboards
- Better Speed
- Better Stability
- Better Redundancy (Backup)
- Mirroring Drives (Backup)
- Types of RAID:
- splits data evenly among two or more hard drives
- referred to as "striping"
- the operating system will only see a single larger hard drive
- because RAID o alternates between drives while reading and writing, overall disk performance increases
- an exact copy of your data on at least one additional hard drive
- referred to as "mirroring"
- uses striping across disks, but places additional data on all disks for data recovery purposes
- Disk Formatting - actually done with Modified Frequency Modulation.
- TB - stands for terabyte
- Some VooDoo PCs come with RAID
- The more drives you put into a RAID configuration, the more likely it is that one of the drives will eventually fail.
- Consequently, with a RAID 0 setup, you may be getting a minor speed boost at the cost of a future data disaster.
- All RAID configurations use two or more hard drives
- The lowest capacity disk in your array will determine the size of your RAID: smallest drive times the # of disks.
- While RAID can be handled by either a hardware or software controller, most modern RAID uses hardware.
- If your motherboard doesn't have Serial ATA or IDE RAID onboard, your can add it via PCI card
- Consumer-level computers typically do not ship with RAID onboard, though many workstation configurations do
