Inhardware-based RAID, a physical controller is used to manage the RAID array. The controller can take the form of a Peripheral Component Interconnect or PCI Express (PCIe) card, which is designed to support a specific drive format, such as Serial Advanced Technology Attachment (SATA) or Small...
A controller is a mediator (could be a software program or a hardware) that fosters communication between an operating system (OS) and an array of physical drives. A RAID controller makes an OS view a set of connected drives as a single logical volume for data storage. Also, a control ca...

associating at least two hard disks in a striping aggregation. Data written to the drives is successively distributed over the physical disks to speed up the read/write performance. Performance increases with the number of hard drives mounted together, provided you use a dedicated RAID controller. ...
Each file is an integral part of the file system, and it is processed by the operating system. At the same time, RAID does not know anything about files; only the operating system can put data in blocks on the disk. A RAID controller (which contains the number of disks, the size of...
RAID 1Disk mirroring and duplexing ( minimum 2 drives ). Drives are used in pairs, and all data is written identically to both drives. Each drive can be duplexed by connecting it to its own interface controller. The failure of one drive does not bring down the system. Instead, the ...
