Multi Disk Storage Recovery

KDR is seeing more Multi Disk storage devices, such as NAS and RAID devices coming into the workshop than ever before. This method of storage used to be reserved only for businesses, but as the prices have dropped more home users now own a multi disk storage device than ever before.

A multi disk storage device is made up of two or more hard drives which run collectively to storage data. This type of storage design offers greater storage capacity, faster access times and can also offer redundancy due to failure.

External Drive RAID Arrays

There are several different types of RAID arrays available. They all have different parameters that will suit a user’s purpose.

Typically a NAS box for the home user will offer a configuration of RAID 0 and RAID 1.

RAID 0 – This has no redundancy and consists of 2 or more hard drives. The data is striped over all of the drives for maximum capacity and speed. If you want to use the full space your drives have to offer you chose this configuration but you sacrifice redundancy.
RAID 1 – This is for mirroring the data. Two hard drives are used and you only have the capacity of one of the drives to use. Data is mirrored onto the other drive meaning if one drive fails the other drive will have a copy of the data stored on it. Hard drive performance and capacity is sacrificed for peace of mind.

There are many other configurations for multi disk storage. We have explained the two most used for NAS storage devices typically used by home users. Most NAS devices have built in operating systems (usually Linux) to deal with multiple tasks that the device can perform. Hard drive problems with NAS devices are the same as single disk storage devices, with the added issue of rebuilding a RAID array and dealing with different file systems.

Kingdom Data recovery can recover data from all types of RAID configurations and file systems. Call us for a free consultation and diagnosis of your RAID device. We only charge for a successful recovery: no data, no fee.
