I was wondering what are the advantages and disadvantages of a Raid 0 and Raid 1 hard drive set up.I'm getting a desktop with 1.5 TB storage. I don't even half that storage, so which choice should I go with?It'll be a Intel i7 processor.Thanks

Raid 1 is mirroring:pRO: If you lose one hard drive, you still have all your data. Your computer will still work.PRO: Reading files is twice as fast since it can read from both drives at the same time.CON: You lose all the storage capacity of one drive.CON: Writing files is not faster than without RAID.Raid 0 is striping:pRO: Reading files is twice as fast since it can read from both drives at the same time.PRO: Writing files is twice as fast, too.PRO: You realize all the storage of both hard drives.CON: If one hard drive crashes, then you lose all the data on both hard drives.Raid 0 is scary. I never ever do it.

For performance, RAID 0 is becoming more popular. This will spread data over the drives.For back-up, Raid 1 is best because it mirrors the information you save. If one drive is lost, the information is still intact on the second drive. I use this on my server.Good question!

RAID 0 isn't strictly RAID at all but striping - the data is spread between two or more drives theoretically combining the capacity of each. RAID 1 is mirroring where identical copies of your data are stored on each drive. You only get the capacity of an individual drive but the data is still accessible even if a drive breaks down.Be careful of any guidance you receive based about performance. Traditionally RAID is implemented with intelligent controllers that are basically special-purpose computers in their own right and are capable of blistering levels of performance. This is the set up that is assumed by most studies examining RAID. However, firmware based RAID, typically included on even basic modern motherboards, is becoming increasingly prevalent. Those are dependent on the host computer to coordinate all disk activity and as a result performance is usually little better than a single drive.

raid for home use? whatever for go buy this one:WD VelociRaptor 600 GB Internal hard drive - 600 MBps - 10000 rpm * about $200 to $250 usd this one can keep up with/ exceed anything a mobo can throw at it!
