SSD Data Extraction and Reconstruction.

SSD hard drives were originally designed and product-ized as direct replacement items for the standardized hard disk drive, having a same physical form factor, interface and configuration implementation. More recent product applications however utilize the underlying solid state storage technology with improved performance and efficiency. Typical of recent SSD applications is the digital storage installed in the latest Sony Vaio laptop. This laptop has an optional Samsung 512GB Model MZRPC512 installed that contains dual 256 GB volumes on a single circuit board. These volumes interface with the Intel CPU Storage management using a single LIF connector cable and can be configured in RAID or as discrete volumes.

SSD Data Recovery Process.

The process of recovering data from a failed and faulty SSD is relatively much more complex than recovering data from a faulty HDD. The difficulty we experience is with a lack of standards. Each manufacturer having different service applications involved in their management. With no standards our technicians must treat each recovery as a unique case. The recovery processes for an SSD therefore requires specialist techniques and knowledge that can match the specific requirements of each brand and model of SSDs

With the Samsung device referred to above; LIF / SATA cable adaptors are not available for our test and recovery lab equipment and expedient soldering is needed to the SSD PCB SATA edge connectors in order to diagnose and resolve failure issues. i.e. data images of each volume being copied to alternative storage and a RAID emulation applied using correct disk order and stripe size in order to reconstruct the data.

These specialist requirements add time and complexity to our procedures which unfortunately add to costs ithat have to be accounted for in our data recovery pricing.

SSD Form Factors and Interface.

SSDs in desktops and laptops are usually either standard 2.5-inch drives or smaller M.2 drives.  SSDs are also available in a PCIe form factor, but these are usually reserved for workstation or server setups.  Whilst the 2.5-inch and M.2 drives look very different, they can share the same SATA interface – which allows for data transfer speeds of up to 600MB/s. However, certain M.2 SSDs use an NVMe PCIe interface instead, which allows for data transfer speeds of up to 16GB/s.

SATA SSDs are faster than mechanical hard drives, but are generally limited to just below 600MB/s. by comparison, a mechanical hard drive will give you data transfer speeds of around 150MB/s.

Form factor, interface, capacity and read/write speeds.

Capacity  refers to the maximum amount of data the drive can store. Read and write speeds are specified as – Sequential and Random.

Sequential speed is the maximum speed when reading or writing  files.  Random access speeds refers to the time taken to access small files randomly across the drive. Sequential read and write speeds are measured in MB/s, and Random read and write speeds  in input/output operations per second (IOPS). Other things to consider are mean time to failure (MTTF) and Endurance . Measured in hours and terabytes written respectively. These provide a good idea of the SSD’s expected reliability and operational lifetime.

Whatever the type, manufacture or form factor Datlabs has the capability and expertise to recover data they fail.

  SATA Connector Type.

There are several types of  SSDs interface connexion,  including SATA, PCIe, M.2, U.2, mSATA, SATA Express. The most common options are SATA and M.2.  SATA-based SSDs are best for older computers.   SATA drives operate at a maximum transfer speed of 600MB/s, whereas other  SSDs have exceeded 3GB/s, nearly five times the SATA maximum. This effectively shows  SATA-based SSDs cannot match  the speed and efficiency of newer controllers such as NVMe.

NVMe Connector.

NVMe, or Non-Volatile Memory Express, is a controller used to replace AHCI, or Advance Host Controller Interface. AHCI is the controller that Hard Drives traditionally use to interface between the SATA bus of a Hard Drive. The NVMe controller was built specifically with SSDs only in mind and is  able to run more than two thousand times more commands compared to a drive on the AHCI controller.

SSD Components.

The key components of a SSD are the controller and the memory. These components contain what is called flash memory, a medium that can be electrically erased and reprogrammed. The two main types of flash memory are named after NAND and NOR logic gates and have similar characteristics. The performance of an SSD scales with the number of parallel chips used in the device. When multiple NAND devices operate in parallel the overall transaction load can be evenly distributed between devices. Most SSD manufacturers use non-volatile NAND flash memory which has the ability to retain data without a constant power supply.

SSD Controller.

The SSD controller system electronics provide a bridge between the host computer operating system and the memory area of the device.  The controller system electronics have embedded firmware functions:

  • Bad Block mapping
  • Read Write Caching.
  • Error Detection and Error correcting code.
  • Garbage Collection
  • TRIM
  • Wear Levelling.

Bad Block mapping, Read Write Caching, Encryption and Error Detection are self explanatory functions  however specific to SSD’s are :-

SSD Garbage Collection.

Unlike hard disk drives (HDDs), NAND flash memory cannot overwrite existing data they must first erase old data before writing new data to the same location. With SSDs, Garbage Collection (GC) is the name for the process of relocating existing data to new locations and allowing the surrounding invalid data to be erased. Flash memory is  subdivided into blocks, and these blocks are divided into pages. Data can be written directly into an empty page, but only whole blocks can be erased. Therefore, to reclaim the space taken up by invalid data, all the valid data from one block must be first copied and written into the empty pages of a new block. It is  then that the invalid data in the original block be erased, making it ready for new valid data to be written.

SSD TRIM Command.

The TRIM command enables the OS to notify the SSD that old data is no longer valid about the time it deletes the logical block addresses from its logical table. The TRIM command  enables the SSD’s GC to skip the invalid data rather than moving it, thus saving time not rewriting the invalid data. This results in a reduction of the number of erase cycles on the flash memory and enables higher performance during writes. The SSD doesn’t Garbage collect these locations it marks them as no longer valid.

Note:  SSD Data Recovery and TRIM control.

SSD Wear Levelling.

Wear levelling is a technique for prolonging the service life of erasable computer storage media, such as flash memory used in solid-state drives (SSDs) and USB flash drives.There are two distinct kinds wear leveling, dynamic and static. Dynamic pools erased blocks and selects the block with the lowest erase count for the next write. Static wear leveling, selects the target block with the lowest overall erase count, erases the block if necessary, writes new data to the block, and ensures that blocks of static data are moved when their block erase count is below a certain threshold. This additional step of moving data can slow write performance due to overhead on the flash controller, but static wear leveling is considerably more effective than dynamic wear leveling for extending the lifespan of solid state devices.

Note: Factors Affecting SSD Failure.

SSD Interfaces.

Apart from associated connectors, interface functionality is incorporated into the controller and includes:

  • Serial attached SCSI
  • Serial ATA
  • PCI Express
  • Fibre Channel  – found on servers

Solid State Drives pose new challenges for Data Recovery companies. The way of storing data on SSD’s is non-linear and much more complex than that of Hard Disk Drives. The control elements of an SSD vary between manufacturers, and the TRIM command zeroes the whole range of a deleted file. Wear Levelling also means that the physical address of the data and the address exposed to the operating system are different.

File systems used on hard disk drives can also be used on solid state drives. The file system supports the TRIM command such that the SSD recycles discarded data. There is no need for the file system to take care of wear leveling or other flash memory operations as these things are handled internally by the SSD.

A TRIM command in the ATA command set, (UNMAP in the SCSI command set) allows an operating system to inform a solid-state drive (SSD) which blocks of data are no longer considered in use and can be wiped internally. The TRIM command was introduced co-incident with SSD availability.

Windows Support for SSD,s

Microsoft Windows prior to 7 do not take any special measures to support solid state drives.  From  Windows 7,  onwards NTFS file system provides TRIM support and the OS detects the presence of an SSD and optimizes operation accordingly. For SSD devices Windows disables “SuperFetch” and “Ready Boost,” boot-time and application pre-fetching operations.  Windows 7 also includes support for the TRIM command to reduce garbage collection for data which the operating system has already determined is no longer valid. It is of benefit to make config changes that prevent SSDs from being treated in the same manner as hard disk drives by cancelling de-fragmentation, not using the available capacity to more than about 75%,  not storing frequently written-to files such as log and temporary files on them if a hard drive is available and enabling the TRIM process.
