RAID Data Recovery .EU
RAID Data Recovery .EU technicians are capable of recovering and repairing inaccessible data from all forms of RAID arrays including: file servers, application servers, web servers, network attached storage RAID systems of any data size.
We provide RAID data recovery from servers and workstations and RAID arrays.
Data Recovery From Different RAID Array Configuration Under The Following Operating Systems:
Windows NT, Windows XP, Windows 2000, Windows 2003, Windows 2008, Microsoft Exchange, Sun, Solaris, IBM AIX HP UX, LINUX, UNIX:
RAID-0 > Striped Array
RAID Data Recovery Process:
What are the different RAID levels?
RAID", (short for Redundant Array of Inexpensive Disks) defining six RAID levels. Each level is a different way to spread data across multiple drives.
RAID Level 0 is not redundant, hence does not truly fit the "RAID" acronym. In Level 0, data is split across drives, resulting in higher data throughput. Since no redundant information is stored, performance is very good, but the failure of any disk in the array results in all data loss. This level is commonly referred to as striping.
RAID Level 1 is commonly referred to as mirroring with 2 hard drives. It provides redundancy by duplicating all data from one drive on another drive. The performance of a Level 1 array is slightly better than a single drive, but if either drive fails, no data is lost. This is a good entry-level redundant system, since only two drives are required. However, since one drive is used to store a duplicate of the data, the cost per megabyte is high.
RAID Level 4 stripes data at a block level across several drives, with parity stored on one drive. The parity information allows recovery from the failure of any single drive. The performance of a level 4 array is very good for reads (the same as level 0). Writes, however, require that parity data be updated each time. This slows small random writes, in particular, though large writes or sequential writes are fairly fast. Because only one drive in the array stores redundant data, the cost per megabyte of a level 4 array can be fairly low.
RAID Level 5 is commonly referred to as striping with distributed parity. RAID Level 5 is similar to level 4, but distributes parity among the drives. No single disk is devoted to parity. This can speed small writes in multiprocessing systems. Because parity data must be distributed on each drive during reads, the performance for reads tends to be considerably lower than a level 4 array. The cost per megabyte is the same as for level 4.
