SSD Data Recovery – Solid State Drive Recovery Service
Data Recovery Services recovery on a full range of solid state drives on flash memory technologies for all makes and models of laptops and notebooks.
Unlike hard disk drives (HDDs), solid-state storage devices have no moving parts. This creates the wrong impression that data is much safer on an SSD. However, this is not the case. SSDs are more vulnerable to some defects than typical HDDs are, including abrupt power loss, magnetic fields and electric charges. Also, because SSDs have a limited number of write cycles, the ability to write to them will eventually wear out, leading to potential data loss.
SSD Data Recovery
Most SSDs use complicated controller technology to extend the reliability and speed of storage. The architecture inside a high performance SSD is more complicated than that in most RAID systems.The algorithms which map logical addresses to physical media locations vary from manufacturer to manufacturer and details are closely guarded commercial secrets.
We developed an advanced SSD drive recovery process of rebuilding multiple sets of NAND flash dumps, unscrambling the code and then taking the numerous unscrambled sets and assembling them into one single drive image. No matter how dependable the storage device, sooner or later it wears out. Often, this occurs without warning after tens of thousands of write/erase cycles. In much the same way a rechargeable battery loses its charge after several hundred cycles, non-volatile SSDs can lose their ability to retain data after thousands of write/erase cycles. This is usually specified by component vendors as endurance.
An example of this wear out process which is typical of SSDs is the Samsung 840 EVO series, which incorporated a lower-cost TLC (triple-level cell) NAND memory whose purpose was to improve storage densities while reducing price. The TCL NAND led to well-known performance issues when reading older data.
When a block loses its ability to retain data or when data errors occur that cannot be corrected by the drive’s error correction (ECC) algorithm, the block is swapped with one from an available spare pool. When the spare blocks are exhausted and another error occurs, the SSD reaches critical failure state and needs to be replaced. SSD management algorithms such as advanced ECC and wear leveling over the entire flash media maximize the drive’s operating life and extend system-level endurance.
Due to the proprietary nature of controller chip manufacturing and programming, every flash and SSD recovery situation is unique. We will first determine the steps necessary to complete your particular SSD recovery, and then we will contact you for approval. With your approval, our engineers will continue with the recovery effort, validate the data and place it on a suitable replacement media, whether that is another drive, USB flash or any other media you chose.
