102. HighPoint-RocketRAID 454 Maximum number of drives, 8 hard disk drives. Supported Hard drives, Up to ATA133. Supported RAID Levels, 0, 1, 5, 10, JBOD. Supported OSs http://www.highpoint-tech.com/USA/rr454.htm

Products SATA II SATA RAID SATA non-RAID e.SATA Product Line ATA RAID RocketRAID 464 RocketRAID 454 RocketRAID 133 RocketRAID 100 ATA non-RAID Storage Device / Accessories ... RR404/454 User Manual (new version) As a 4 channel ATA133 RAID adapter, the RocketRAID 454 supports up to 8 IDE hard disk drives, and provides multi level RAID support including RAID 0, 1, 5, 10, JBOD. The RocketRAID 454 is a high quality, cost-effective solution for your mass storage needs. The RocketRAID 454 can support multiple RAID arrays, and the 4 independent ATA133 channels provide parallel disk/array access. Due to the RocketRAID 454's RAID 5, 10 and capabilities, data storage and retrieval is dramatically faster than single drive systems. For RAID 1 and 10, the RocketRAID 454 provides disk mirroring, hot-spare options for automatic array-rebuilds, hot-swap support for swapping failed disks on the fly (works with Hot-Swap capable mobile racks such as Rocket Mate), and disk failure notification (audible alarms, visual warning messages).

RAID (Redundant Array of Independent Disks) What is RAID? The basic idea behind RAID is to combine multiple small, inexpensive disk drives into an array which yields performance exceeding that of one large and expensive drive. This array of drives will appear to the computer as a single logical storage unit or drive. RAID is a method in which information is spread across several disks, using techniques such as disk striping (RAID Level 0) and disk mirroring (RAID level 1) to achieve redundancy, lower latency and/or higher bandwidth for reading and/or writing to disks, and maximize recoverability from hard-disk crashes. The underlying concept in RAID is that data may be distributed across each drive in the array in a consistent manner. To do this, the data much first be broken into consistently-sized "chunks" (often 32K or 64K in size, although different sizes can be used). Each chunk is then written to each drive in turn. When the data is to be read, the process is reversed, giving the illusion that multiple drives are actually one large drive. Who Should Use RAID?

PC Mechanic's Floppy Drive Page Explains what a floppy drive is and contains instructions on how to remove or install one. By Mary Bellis In 1971, IBM introduced the first "memory disk", as it was called then, or the " floppy disk " as it is known today. The first floppy was an 8" plastic disk coated with magnetic iron oxide; data was written to and read from the disk's surface. The nickname "floppy" came from its flexibility. The floppy disk was considered a revolutionary device at the time for it's portability which provided a new and easy physical means of transporting data from computer to computer.

BIOS A special piece of software built into the motherboard of most computers that contains the basic processes executed when starting up.
