INSTRUCTIONS FOR PACKING YOUR RAID

It is important to pack your device properly to minimise the risk of damage while being transported to the laboratory.

Carefully wrap the device in static-free material, bubble wrap, foam or similar.
Use a rigid box stuffed with cushioning material that is deep enough to protect the device against possible impacts. Place the device in the box and cover with more stuffing material. Make sure the device is securely positioned inside the box to prevent it from shifting during transport.
Close and seal the box and write the request number in a visible location on the box.

3. Recovering the data from your RAID

When your RAID is received at our laboratory, the first thing we do is diagnose the problem free of charge and provide you with a fixed quote.

Once you accept our quote, our technicians will start work recovering the data from your RAID. Once your RAID is stabilised, we will send you a list of the recovered files. Up to this point, you pay nothing.

If you approve the list, we will copy the data recovered from your RAID to a new device selected by you when you approved the quote, which will be delivered to you at no additional cost.

RAID recovery. We recover data from RAIDs at any level

A RAID, or Redundant Array of Independent Disks, is a data storage system that was created to overcome the space, security and speed limitations posed by hard drives.

To achieve this, RAID systems are composed of various data storage units (hard drives or SSDs) working inside the same logical unit. This way, the operating system identifies only one device, regardless of the activity and behaviour, thereby expediting computer-disk processing.

How does a RAID work?

RAID storage systems are devices made up of integrated internal disk circuits that share and distribute the information in such a way as to speed up the access time, ensure the recovery of a system if one of the disks malfunctions and provide redundancy (repetition of the information that allows the contents to be reconstructed even if data is lost). This last functionality is achieved thanks to a restoration and re-establishment principle. If one disk fails, the redundant information on the healthy disk is used to reconstruct the data missing from the damaged disk.

RAID technology offers an additional advantage over hard disks: disks can be replaced with the equipment running. In other words, the system does not have to be shut down to replace the disk.

RAID levels

There are different ways of configuring RAID technology which offer different possibilities and “types” or levels. Each one offers a different combination of speed, security and capacity. It is not that one RAID system is better than another, but that different systems offer different possibilities to meet the user’s needs. Knowing how to differentiate between them is therefore critical in order to make a good choice.

The fastest RAID system which offers increased capacity depending on the number of disks.

RAID 0 technology is a system that requires at least two disks connected in parallel over which the information is distributed. The data is broken down and distributed among the different storage units. Its capacities are aggregated, generating a single, large volume of information in the computer and providing very rapid access to the data.

However, this system does not feature redundancy and therefore does not permit failover. Consequently, this system can only be used if there is a back-up copy.

Also known as mirroring. This level of “array” or matrix offers absolute redundancy by constantly duplicating the information from one unit to another and creating a backup copy of the information. In the event of a malfunction, the information can be recovered and the work can continue without the system having to be shut down.

Because this RAID level works with pairs of storage units, there must be at least two disks. In order to expand the capacity, it would be necessary to add two additional disks to make a copy or “mirror” of each one.

In contrast to the security of information recovery, the capacity is limited to the disk with the least space.

This RAID level works with at least three disks, two of them with data storage capacity which are accessed at the same time to get to the information. The remaining disk is used to store the parity data. In this way, if one of the units in this level malfunctions, the information stored in that unit is regenerated on the spare disk. However, a problem arises when a second disk malfunctions, in which case the information is lost.

This system offers high capacity and a high performance level.

The difference between this level and the previous one is that this type of technology makes it possible to access each one of the disks making up the logical unit individually.

This is one of the most frequently used RAID systems. The logical unit is composed of at least three disks. The information is distributed in bands and each band has a parity block. In other words, unlike RAID 3, RAID 5 does not use one of its units for parity. Rather, a certain amount of space is reserved on each disk to store such information (parity block), so that all are replicated and available to recover the data if necessary. This guarantees that the information will be recovered if one of the disks fails by duplicating the data from that disk on a spare disk. However, this will not be the case if another malfunction occurs before the information is written to the spare unit, in which case all of the data from the array would be lost.

This level surpasses RAID 5 in operativity. Although the functional structure is similar, the options are maximised at this matrix level. The number of disks required to make up the logical unit increases from three to four, thereby increasing capacity. The information is distributed among the storage units in bands but rather than allocating a band alternative to parity, this technology allocates two bands per disk, which affords greater security when faced with a loss of data. While RAID 5 can withstand one disk failure, RAID 6 can withstand failures in two disks without a loss of data. It also offers faster regeneration of the information.
