How Do We Recover Your RAID Data?
We have an up-front way of recovering data from RAID arrays. It comprises on steps:
- Make a call OR send us an email.
- Send your damaged media to one of our UK located data recovery centres.
- After reception of media it will be forwarded for free diagnosis by our RAID recovery experts. After complete analysis, a comprehensive analysis report will be sent to you.
- On your approval we will start recovering data. After recovery data will be copied to media of your choice.
- Recovered data along with the original media will be shipped to you.
Our data recovery engineers can recover RAID arrays damaged by ordinary tragedies, user mistakes, unintentional removal or formatting, water or other liquid dropping etc, diskette breakdown, RAID booting scheme botched, RAID controller breakdown, hateful software program assault such as virus, Trojan, spy ware etc and RAID stoppage because of electric problems.
Our RAID engineers use up-front and proven methods and techniques to salvage your critical data from damaged RAID arrays. Our data recovery experts have provided and can provide data recovery services for the, Ciprico, Dell, Bus Logic, AMI and many other regulators of RAID arrays.
Data Recovery for All RAID Types
Redundant array of independent disks comes in nine types including a non-redundant array (RAID 0).
RAID-0:
It is often called “Striping”. This name is due to the fact that the data is stripped in small portions and spread throughout the disks. Its performance is out class but it is not “fault-tolerant”. There is no data protection if one drive corrupts then the whole system goes down. Array capacity is equal to the combined capacity of member disks. It requires two physical disks.
RAID-1:
Level one is called the “mirroring” level since identical data is written on member disks for redundancy. This technique is very useful for quick recovery of data but data entry time is slower. It is very common because of its simplicity and having high data availability rate. It also requires two physical disks.
RAID-2:
It has become obsolete. Lately it was used for the correction of RAM errors which are called Hamming Codes.
RAID-3:
This type also uses striping mechanism but with a difference as there is a dedicated parity disk which contains the parity data. It is not used quite often as its performance is poor while retrieving little amounts of data as in a database. For sequential data requests it performs quite remarkably.
RAID-4:
It utilizes a block level data striping technique with a dedicated parity drive. Array capacity is equivalent to the total capacity of the member disks subtracting the capacity of a single memory disk. It is useful for transactional operations since it can’t carry out large file transfers.
RAID-5:
In this type the parity data is written on some or all the member disk drives. It overcomes the write bottleneck inherent present in RAID-4, though parity calculation process remains the only bottleneck. Array capacity is equal to the total capacity of member disks minus the capacity of a single member disk. It highly suits a transaction oriented environment and can be optimized for large sequential access.
RAID-6:
It is similar to RAID-5 but in addition includes a independent sets of parity instead of one, which is distributed across some or all of the member disk drives. Adopting this technique ensures extreme fault and disk failure tolerance.
RAID-7:
It is basically RAID-3 with a real time operating system as a controller for a better management of data and cache to speed up the access. It is a registered trademark of ‘Storage Computer Corporation’.
RAID-10:
It involves an array of stripes in which each stripe is a RAID-1 array of drives. It offers higher performance than RAID-1 but at a great cost.
But nothing is perfect in its character and in this way even RAID array can give up its job. When it happens then Business Company goes at big risk. In this situation you need our help — Geeksnerds services available for RAID arrays 24/7/365
