Redundant array of inexpensive disks. Its a cheap method of backing up data in a running server.
"RAID" is short for "Redundant Array of Inexpensive Disks." RAID are groups of storage systems. RAID Recovery is the act of recovering data from those storage systems.
Our experience of recovering the data from failed Raid Systems is unparalleled. We recover data from failed RAID 0, RAID 1, and RAID 5 systems regardless of configuration or manufacturer. We also recover data that has been rendered inaccessible as the result of a rebuild failure.
Products supplied by Areca are mostly computer storage systems. These includes SATA Raid, HBAs SAS RAID HBAs and non-RAIDs, Mezzanine Boards, RAID controllers and Internal RAID racks.

RAID 6 provides the most fault tolerance of any standard RAID disk arrays (RAID 0, 1 , 5, 6, and RAID 10). If any two disks in a RAID 6 array fail and are removed, then two new blank disks can be installed and no data has been lost. RAID 1+1 or most other "layered" RAID systems can provide more fault tolerance than RAID 6, tolerating the failure of any 3 disks. Some experimental non-standard disk arrays can provide more fault tolerance with less overhead, such as the parchive system. Nearly all distributed file systems and distributed version control systems can be set up so that if one machine is completely destroyed by fire, all the data can be recovered from a backup machine in another building.
You copy the RAID or Non RAID drivers file from the cards driver CD to the disk Read the documentation to find out which folder on the CD contains these files The card drivers must be installed during the Windows installation. you are given an opportunity at the beginning of the Windows installation to provide the drivers on floppy disk or a USB device.

Hardware RAID uses a dedicated controller card to manage the RAID array, offloading processing from the host system and often providing better performance and reliability compared to software RAID. It typically supports advanced features like battery-backed cache and can handle multiple drives more efficiently. Additionally, hardware RAID can offer greater compatibility with various operating systems and improves data recovery options in case of drive failure. However, it may be more expensive and less flexible than software RAID solutions.
Software-based RAID (Redundant Array of Independent Disks) is a data storage virtualization technology that manages multiple hard drives using software rather than dedicated hardware. This approach allows the operating system to handle RAID functions, such as data redundancy and performance optimization, without requiring a separate RAID controller. While software RAID can be more flexible and cost-effective, it may also impose a greater load on the CPU compared to hardware RAID solutions. Common implementations include RAID configurations found in operating systems like Windows, Linux, and macOS.
RAID 7 is triple parity RAID 6 is double parity.
