For highest performance RAID5 and RAID6 are used.
RAID 0 and 1 are also used, but RAID0 is not advised since it offers no fault-tolerance at all.
Unfortunately these RAID0 are still used in NAS systems and also in very big external harddisks.
The RAID5 and RAID6 systems are very reliable, but can also fail when several harddisks fail at the same time.
Also fire or water can damage these systems.
At present time, there are many variants of these RAID-systems, e.g. from Dell; HP (Compaq), Intel etc...
In the past years we’ve build a very large expertise to recover the data in a very short time.
We always use copies of the harddisks, to avoid further damage to the data.
This implies that it takes some more time before we can start, but it also guarantees that no more damage is done to the data.
For recovery of a RAID system, a working controller is not neccessary; we reconstruct the data independently from the used controllers.
Like in all our other recoveries, here also applies: No data, No costs
