Parts of an SSD hard drive
An SDD (solid state drive) is an alternative storage device to the traditional mechanical hard drive. SSD drives store data using memory based on flash technology. This technology offers much more speed than mechanical hard drives and of course they are silent. SSD drives are made up of a board that contains various electronic components, as well as the controller and memory blocks. The controller is in charge of making requests and executing orders from the PC to fetch the information or write it to the place it touches (memory blocks). We could define memory blocks as boxes or shelves where we store information. It is not saved in an orderly and intelligible way for reasons of space and speed optimization. That's what the controller does.
PROBLEMS WITH AN SSD HARD DRIVE?
If you encounter a situation similar to this:
- Your computer does not recognize the SSD disk?.
- The SSD is damaged and won't boot?
- Has the SSD broken or stopped working?
- Is the SSD hard drive slower than usual or does the computer hang?
- Give an unexpected error when trying to access information on the SSD?
- Any other situation not mentioned above.
We are specialists in diagnosis and data recovery.
We work with all SSD manufacturers: A400, Samsung, Crucial, Sandisk, Toshiba, Western Digital, Seagate, MSI, Corsair, Kioxia, Kingston, LaCie, Sandisk, PNY, Intenso, Freecom, Transcend, Adata, G-Drive, G Raid...
SSDs offer high performance at a mid-range price and with a capacity that is currently low compared to a mechanical hard disk. They are ideal for use in operating systems (system disks) but Laby recommends against using them exclusively for data storage. Except for very high-end SSDs, memory blocks have a limited read and write lifetime: The famous TBW (Terabytes Written) is defined by JEDEC as the number of terabytes that can be read and written on an SSD until its memory cells are “exhausted”, and is defined in the JESD218 standard.
To avoid the loss of sensitive information, it is interesting to use SSDs as system disks and not as storage disks. Also, traditionally, on a mechanical hard disk, if the data is erased and not overwritten, there is usually a high success rate in the data recovery process. Nowadays, in SSDs and memory cards, this percentage drops due to the use of the TRIM command in current operating systems.
Due to the way of reading / writing the information inside the memory blocks (flash technology) every time you want to modify a “sector” inside the memory block, you cannot do it directly. An entire block (page) must be read, loaded into the buffer (swap memory), modified and the modified information stored again.
It is an inefficient process and slows down the speed. To speed up the write process, when data is erased from an SSD or memory card, the operating system launches the TRIM command. This command searches for cells marked as deleted and performs the process of resetting them to “0”. In this way they will be ready to be used without the need to load them into the buffer, modify the content and save the information again. If you delete data from an SSD or memory card, disconnect the device as soon as possible and avoid using it in conventional operating systems to ensure the data recovery process.
More than 29.800 devices in stock for fast and economical service.
Own software and customized intranet.
SSD disks 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.
To avoid further damage to the device:

SSD HARD DRIVE DATA RECOVERY PRICES
The price to recover data from SSD hard drives will always depend on the damage suffered by the device, together with the hours of work 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 various failures. Below we detail the most common breakdowns and the reference prices:
SSD hard drive data recovery pricing is mainly driven by two factors:
Damage to SSD hard drive components (whether a firmware problem, on-board electronics, controller or memory blocks) and the labor hours involved in the recovery.
At Laby we will NOT charge you a higher amount for data volume. Only because of the difficulty of access. This difficulty is also noticeable in current NVME hard disks or Chinese models with “standard” controllers but with internal encryption.
In many cases SSD failures that are not recognized in the system are the result of a failure in the firmware of the device, either due to corruption or because it cannot be read by the controller and therefore does not know how to work. Each time the SSD is powered on, the main controller reads an area of the memory blocks where there is important operational information (S.A -Service Area- ) in the same way as in traditional hard disks. If the S.A is corrupted by a malfunction or the memory blocks are degraded due to usage (remember the term TBW) the SSD will not be able to initialize.
In some cases, it is possible to read the information by means of modified firmware that allows access to data through the controller itself. At other times, this is not feasible (damaged controller, unknown firmware, electronic board failure) and the only possibility is to desolder the memory blocks and read them.
Once read, several highly complex processes must be carried out to obtain the data. These processes recreate the tasks performed by the controller physically on a chip in a logical manner. And among these operations is the XOR decryption process. It is a key used by the controllers to distribute the workload over the memory blocks.
These keys, often vary, from one controller to another or in the various revisions that are appearing during the production of the SSD disk so that sometimes it takes several weeks to find the key and proceed to retrieve the information from the SSD.

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.
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 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.
Apple devices, both iPhone, iPad, iMac, MacBook, Mac Mini, etc. They are reliable, elegant, powerful and easy-to-use devices.
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.
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 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.
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 are used to store information from devices such as cameras, cell phones or tablets. They differ in their storage capacity and read/write speed.
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.
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.
We offer the service of deletion and destruction of secure data with a certificate, either in our laboratory or remotely.
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.
