WHAT IS A RAID SYSTEM?
What is a RAID system?
- Data redundancy and therefore disaster recovery.
- Optimization and speed, which will allow for performance.
- A combination of the two previous ones, providing a compromise between speed and security.
- A single volume with multiple hard drives.
RAID DISK PROBLEMS
- The RAID is inaccessible
- A disk has been replaced and the RAID has stopped working
- The RAID has been REBUILD and other RAID disks have failed
- The RAID controller has been damaged and the logical drive or LUN cannot be remounted.
- The RAID disks make noises or warning lights turn on on the controller.
- The RAID does not work after restarting the machine or computer.

TIPS TO AVOID LOSING DATA
It is important to know what type of RAID we want to perform and look to the future to be scalable. We can define RAID tipology within three options: Speed, capacity, security and then, a mixed tipology. It is also important to know what type of content will be stored inside the RAID in order to configure the BLOCK SIZE.
This will determine the write/read speed as well as the capacity that will remain after performing file copy operations.
If you are looking for full capacity and speed, you should opt for RAID 0. This will provide a drive whose capacity will be the sum of all the devices (3 x 1TB disks will provide a 3TB drive in total). It is an extremely fast system (it allows writing and reading on all three disks simultaneously), but in case of loss of a disk, all information will be lost.
If you are looking for security, you should opt for RAID 1. This will provide a drive whose capacity is half of the drives (2 x 1TB disks will provide a 1TB drive in total). It is a slow system, because it has to write in both devices at the same time the same information, although it is a fast reading system (it can read from both simultaneously).
In case of loss of a disk, you will be able to work with the other disk, replace the damaged one and the system will perform a “REBUILD” of the damaged disk to continue working normally. This process will make your system slow
If you are looking for something in between, you can opt for a RAID 5. This will provide a unit whose capacity will be N= N-1 N where N will be the number of disks in the RAID (Minimum 3 disks). For example 5 x 1TB disks will offer a capacity of 4TB available. With RAID 5 it is possible to lose a device and continue working, replace the damaged one and the system will perform a “REBUILD” of the damaged disk to continue working normally. This process will make your system slow
RAID 6, could be considered an extension of RAID 5 where it allows two simultaneous disks to be broken and the system to continue working.
However, the following should be kept in mind: During a REBUILD the disks are made to work at maximum performance. If we add to this process the workload requests by users, programs or similar, we will be forcing the disks to a high level of stress. This should not be a problem a priori, but in most cases the disks already have many hours of work and their surface or reader units are not at 100% performance so it is possible that the REBUILD fails in the middle of the process, leaving the system and/or the RAID data inaccessible.
To avoid this situation it is interesting to have a disk replacement plan according to the use and workload of the RAID system. Likewise, it is essential to configure the disk alerts and control the RAID periodically to ensure that there is no anomaly, since one of the disks may fail without realizing it and after a few months another one may fail.

HOW MUCH DOES RAID DATA RECOVERY COST?
RAID SYSTEM DATA RECOVERY PRICES
The price for recovering data from RAID systems will always depend on the damage suffered by the device, together with the working hours and technical equipment required to carry out the recovery processes.
In any case, a prior diagnosis is necessary to detect the type of failure or combination of several failures.

WHAT DEVICES CAN WE RECOVER AT LABY?
Data Recovery from Mechanical Hard
HDD disks have as main components the metal plates (disks), where the data is stored, and the heads that are responsible for accessing the information. The most common hard disk.
SSD Hard Drive Recovery
SSDs do not move, hence the name solid state. The information is stored in blocks and no headers are required to access it. It is much more efficient and faster than an HDD hard disk.
External Hard Disk Drive Recovery
External hard disks allow us to store outside the computer all the important information of which we want to make a backup copy. But one failure can cause us to lose all this data.
iPhone, iPad, iMac or MacBook
Apple devices, including iPhone, iPad, iMac, MacBook, Mac Mini, etc. They are reliable, elegant, powerful and easy to use.
Laptop Hard Drive Data Recovery
On the laptop hard disk we store important work or home information. If a failure occurs, it can cause us to lose all this valuable personal data.
Data Recovery NAS, SAN and
A SAN, NAS or DAS disk is a compact enclosure consisting of several hard disks that are connected via a network cable to the system, hence the common name network hard disk.
Data recovery from RAID systems
RAID disks are a redundant group of independent disks. They can be HDD disks or SSD disks and together they form a storage system to distribute or replicate data.
Recovery of USB Flash Drives
Pen drives or USB flash drives consist of one or more memory blocks. They work in many cases like SSD devices (same Flash technology).
Memory Card Recovery
Memory cards are used to store information from devices such as cameras, cell phones or tablets. They differ in their storage capacity and read/write speed.
Ransomware or Virus Recovery
We recover data encrypted with viruses or ransomware. Ransomware is extortive software: its purpose is to prevent you from using your device until you have paid a ransom. Depending on the type of ransomware, either the entire operating system or only some files are encrypted.
Mobile and Tablet Recovery
In mobile devices such as smartphones or tablets, recovery processes can be performed by analyzing the electronics of the damaged components or by performing the chip off process.
FAQs ABOUT RAID SYSTEMS
A RAID (Redundant Array of Independent Disks) system is a technology that combines multiple storage units into a single logical array to improve performance, capacity or data redundancy. Depending on the type of RAID chosen or configured, we will have higher read and write speed, greater storage capacity, greater fault tolerance and in some cases the ability to recover data in the event of a drive failure.
A RAID system works by distributing data across a minimum of two drives up to multiple hard drives in different configurations. Common configuration methods include RAID 0, RAID 1, RAID 5, RAID 6 and RAID 10.
In RAID 0, data is striped and stored on different disks, which improves performance, but does not provide any security.
In RAID 1, data is mirrored on two disks to provide greater security and fault tolerance at the expense of write performance.
RAID 5, RAID 6 and RAID 10 combine performance and redundancy features through the use of parity or CRC calculations of stored data, either on the disks themselves or to additional drives within the RAID itself.
The main parts of a RAID system include the storage drives (mechanical hard disks or SSDs), a RAID controller (hardware or software) that manages the write and read operations of the disks, and a management system (usually an O.S. such as Windows or Linux) that allows the RAID operation to be configured and monitored. In addition, connecting cables such as SATA, SAS, FC (Fiber Chanel) and specific adapters (enclosures) may be used to connect disks.
If your RAID system has stopped working, it may indicate a possible failure of one or more storage drives, an error in the RAID configuration, or a problem with the RAID controller. It is recommended to check the drive connections, make sure the RAID controller is working properly and verify the RAID configuration. It is also advisable to perform an updated data backup before attempting any solution to minimize the risk of data loss.
The chances of recovering data from a damaged RAID system depend on several factors, such as the cause and severity of the failures, the RAID level used, and the availability of specialized tools and expertise. In some cases, it is possible to recover data using specialized data recovery software and techniques. However, when the failure comes from the storage drives, depending on the type of RAID used, recovering data on a damaged RAID can be a complex process. It is advisable to consult with a specialized data recovery lab to assess the RAID status and determine the options available to recover the data.
