| DIFFERENT TYPES OF RAID The most popular RAID level are 0, 1, 3 and 5, their definition of RAID levels are: RAID 0 Known as disk striping. It combines disks that are used to improve some performance, but there is no logic to protect/recover data. Pros/Cons Fast data transfer on large blocks of data I/O. No parity check for fault-tolerance. -------------------------------------------------------------------------------- RAID 1 This is known as mirroring, where data is written to two different disks at the same time, and data can be read from either disk. Pros/Cons Secure against disk failure. Double the cost of storage. -------------------------------------------------------------------------------- RAID 2 Disk striping with several disks similar to RAID 0, but a small percentage of those disks were set aside to be "check disk," A special Hamming Error Correction Codes is implemented. Not used because of high performance penalty. -------------------------------------------------------------------------------- RAID 3 Striping data over several disks. Parity interleaves at byte level and is stored in a dedicated disk. Pros/Cons Fastest for large-file transfer, lower cost for data security. If the dedicated parity disk failed, all data integrity is lost. -------------------------------------------------------------------------------- RAID 4 Similar to RAID 3, striping data over several disks. Parity interleaves at block level rather that byte level and is stored in a dedicated parity disk. RAID 4 improves read access but suffers form a write penalty since every write must access the parity disk. -------------------------------------------------------------------------------- RAID 5 Striping data and parity over several disks with no dedicated disk for parity. Pros/Cons Higher I/O rate for writing data and since no dedicated parity disks, no data loss for any disk failure Not as fast as RAID 3. There are of course, RAID level's 10 and 50 but probably well beyond the scope of what you need to know. |

| I would recommend that if you do go for RAID 0 than invest in a backup prog like Ghost or an external drive to save important stuff. IMO it is not really worth raiding unless you are doing stuff like video-editing. |

Yes. It is also so close to twice as fast as a single disk you will probably ejaculate all over your monitor. I would advise buying some windscreen wipers along with your motherboard..... |
