With years of experience in the data recovery field and qualified technicians working around the clock, 24Hour Data Australia recovery in Melbourne and Perth has the technical expertise to handle complex RAID recoveries.
When your RAID fails, do not attempt to repair or rebuild your RAID array. If done incorrectly or with the wrong stripe block size or disk order, this may corrupt your data permanently. Don't risk it!

Different Levels of RAID
RAID 0 - Striped Disk Array without Fault Tolerance: Provides data striping (spreading out blocks of each file across multiple disk drives) but no redundancy. This improves performance but does not deliver fault tolerance. If one drive fails then all data in the array is lost.
RAID 1 - Mirroring Volume: Provides disk mirroring. Level 1 provides twice the read transaction rate of single disks and the same write transaction rate as single disks.
RAID 5 - Block Interleaved Distributed Parity: Provides data striping at the byte level and also stripe error correction information. This results in excellent performance and good fault tolerance. Level 5 is one of the most popular implementations of RAID.
RAID 10 (or RAID 0+1) - A Mirror of Stripes: Not one of the original RAID levels, two RAID 0 stripes are created, and a RAID 1 mirror is created over them. Used for both replicating and sharing data among disks.
Data recovery process becomes much more complicated when dealing with a failed hard drive which is part of a RAID array, and this is why it is important for professional, experienced data recovery specialists to handle the recovery.
