Diagram of a RAID 1 setup. RAID 1 consists of an exact copy (or mirror) of a set of data on two or more disks; a classic RAID 1 mirrored pair contains two disks.This configuration offers no parity, striping, or spanning of disk space across multiple disks, since the data is mirrored on all disks belonging to the array, and the array can only be as big as the smallest member disk.
RAID ( / reɪd /; " redundant array of inexpensive disks " [ 1] or " redundant array of independent disks " [ 2]) is a data storage virtualization technology that combines multiple physical disk drive components into one or more logical units for the purposes of data redundancy, performance improvement, or both.
RAID 01, also called RAID 0+1, is a RAID level using a mirror of stripes, achieving both replication and sharing of data between disks. [3] The usable capacity of a RAID 01 array is the same as in a RAID 1 array made of the same drives, in which one half of the drives is used to mirror the other half.
After the raid, U.S. forces returned to Afghanistan with bin Laden's body for identification and then flew over 850 miles (1,370 km) to the Arabian Sea, where he was buried in accordance with Islamic tradition. [9] Al-Qaeda confirmed bin Laden's death on May 6 through posts made on militant websites and vowed to avenge his killing. [10]
RAID 5E, RAID 5EE, and RAID 6E (with the added E standing for Enhanced) generally refer to variants of RAID 5 or 6 with an integrated hot-spare drive, where the spare drive is an active part of the block rotation scheme. This spreads I/O across all drives, including the spare, thus reducing the load on each drive, increasing performance.
Intel Rapid Storage Technology ( RST) is a driver SATA AHCI and a firmware-based RAID solution built into a wide range of Intel chipsets . Currently also is installed as a driver for Intel Optane temporary storage units. It contains two operation modes that follow two Intel specific modes rather than the SATA standard.
RAID 6 – Like RAID 5, but with two parity segments per stripe. RAID 10 – Take a number of RAID 1 mirrorsets and stripe across them RAID 0 style. RAID 10 is distinct from RAID 0+1, which consists of a top-level RAID 1 mirror composed of high-performance RAID 0 stripes directly across the physical hard disks.
The raid sparked a national debate about press freedom focused on Marion, a town of about 1,900 people set among rolling prairie hills about 150 miles (241 kilometers) southwest of Kansas City ...
