What is Disk Striping and its importance in Data Recovery?
This is a method of combining multiple drives into one logical storage unit. Striping partitions the storage space of each drive into stripes, which can be as small as one sector (512 bytes) or as large as several megabytes. These stripes are then interleaved in a rotating sequence, so that the combined space is composed alternately of stripes from each drive. RAID that uses striping complicates data recovery significantly. The data is no longer placed in relatively simple fashion on a single hard disk, but rather, distributed across many drives. Despite this complication, it is possible to do data recovery in most cases; it just costs more due to the complexity of the array.
