RAID, an acronym for Redundant Array of Independent Disks, is a technique for storing computer data, by dividing and/or reproducing it, on various hard disks. These disks are (by default) arranged into arrays (as the name suggests) for redundancy and increase performance and reliability, when compared to single disks. To put it simply, when two or more hard disks are used together, by applying RAID technology, they form a RAID array. Based on their arrangement, they are categorized as RAID-0, RAID-1, RAID-3, RAID-5, RAID-6, RAID-7, RAID-10, RAID-50, RAID-53, RAID-S, RAID-01, etc. These configurations or levels, are used in different data critical applications and have different levels of performance and fault tolerance benefits...

There is nothing more alarming when the computer for work or personal use has passed away. Indeed very important data are lost and probably the world seems to crumble under the feet of the novices and non-professionals. A common scenario and can also happen when the hard drive has spat or when a false manipulation caused an unintentional formatting. It is also possible that this operation was carried out voluntarily, but few data have been inadvertently omitted and not been saved.

Starting today, know that it is possible to retrieve data permanently deleted from the PC or can no longer be accessible and that, through a simple software. There are dozens, even hundreds of freeware recovery, but be aware that the most efficient are mostly paid. A statement which, however, proves not to be true to one hundred percent as there are some exceptions to the rule but must still know them. Among the rare and excellent software for data recovery is the soft called Stellar Phoenix...
