¿QUÉ ES UN SISTEMA RAID?
Qué es un sistema RAID
Un sistema RAID, es la combinación de dos o más discos para formar una o varias unidades lógicas que funcionan como conjunto tanto si queremos hacer copias como si queremos multiplicar el espacio pero usándolo como un único disco. Es decir podremos tener varios discos pero solo ver una sola unidad de almacenamiento.
Según la tipología de RAID escogida, se conseguirá:
- Redundancia de datos y por tanto seguridad ante desastres.
- Optimización y velocidad lo que permitirá rendimiento.
- Combinación de las dos anteriores dando un compromiso entre velocidad y seguridad.
- Único volumen con varios discos duros.
PROBLEMAS DISCOS DEL RAID
Estos son los típicos problemas de los discos en RAID:
- El RAID es inaccesible
- Se ha reemplazado algún disco y el RAID ha dejado de funcionar
- Se ha realizado el REBUILD del RAID y otros discos del RAID han fallado
- La controladora RAID se ha dañado y no permite remontar la unidad lógica o LUN
- Los discos del RAID hacen ruidos o se encienden luces en la controladora de aviso
- No funciona el RAID tras reiniciar la máquina o ordenador

CONSEJOS PARA NO PERDER DATOS
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.
En Laby somos especialistas en la recuperación de dispositivos RAID (tanto de hardware o software conocidos como DELL, COMPAQ, HP, LINUX, WINDOWS) y de otros fabricantes como QNAP, SYNOLOGY o fabricantes de NAS o DAS.

¿QUÉ DISPOSITIVOS PODEMOS RECUPERAR EN LABY?
Mechanical hard disks
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.
Vehicle Forensic Analysis
What is vehicle systems forensics? It is a process by which a wide range of data and information is extracted from vehicles, which can be used in collision and serious crime investigations. At Laby, we offer specialized services to support our clients in obtaining and analyzing vehicle data. Our team
SSD Hard Drives
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 Drives
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 or MacBook
Apple devices, both iPhone, iPad, iMac, MacBook, Mac Mini, etc. They are reliable, elegant, powerful and easy-to-use devices.
Laptop hard disks
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.
NAS, SAN and DAS disks
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.
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.
Pendrives and 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 cards
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.
Virus or Ransomware
We recover data encrypted with viruses or ransomware. Ransomware is extortion software: its purpose is to prevent you from using your device until you have paid a ransom. Depending on the type of ransomware, the entire operating system or just some files are encrypted.
Mobile Phones and Tablets
In mobile devices or smartphones or tablets, the recovery processes can be carried out through the analysis of the electronics of the damaged components or, by carrying out the chip off process.
Data deletion
We offer the service of deletion and destruction of secure data with a certificate, either in our laboratory or remotely.
Computer forensics
Computer forensic analysis and expert evidence. We recover and certify critical information with legal value for companies and individuals. We have collegiate computer experts to carry out certifications, expert analyzes and reports with legal value.
