SSD, short for the solid-state drive, is a data storage device using solid-state memory to store persistent data. It offers superior performance, uses less power, runs silently, shortens access time and is more resistant to shock than common hard drives, and solves the problem of physical constraints by replacing hard disk drives with high speed circuitry. Instead of a rotating disk, a solid state disk uses memory chips (typically DDR RAM or Flash Memory) to read and write data.
SSDs are entirely electronic. The system still has to go through more hoops to get at SSD data than RAM data, but all of the mechanical delay is eliminated - so SSDs can retrieve data much faster than a hard drive. For other uses, the drive will be faster but the difference may not be as dramatic, particularly if you're writing to the drive.
Gradually, more and more people are using SSD disk for its safer and more robust technology. Whatever, computer users still can be divided into two categories: ones who have lost data, and others who will lose data. Is your data safer on a solid state drive?
Most solid state memory today consists of NAND-based flash memory, which retains memory even without power. Solid state storage devices are manufactured with one of two types of NAND flash memory: Single-level cell (SLC) and Multi-level cell (MLC). MLC memory has more density, and therefore is less expensive, but is more prone to errors and also has fewer write/erase cycles.
The durability of a solid state drive is measured in its write/erase cycles, or the number of times a block can be erased and re-written to before that block fails. A technique called wear leveling dynamically maps logical blocks to physical blocks, to prevent premature failure of any block from too many write/erase cycles. This, along with multi-channel flash microcontroller technology, adds to the durability of a solid state drive, but block failure is also one of the key reasons for solid state drive data loss.
Other common reasons for SSD failure and solid state drive data loss include:
Whenever data loss occurs, you need to recover data from SSD disk/card.
Just as with common hard disks, if the data loss isn’t caused by physical damage to the SSD drive, you can recover it with an SSD recovery program. Because when the data is deleted, formatted or lost due to other reasons, the place occupied by the data is only marked as “available to reuse”, telling the system that new files can be stored here.
In order to maximize the chance of recovering data from your SSD drive, what comes first in your mind should to stop using your SSD right now. Any new file you save on it could possibly overwrite your lost data, which make your data lost permanently.
One expert data recovery software from EaseUS: EaseUS Mac Data Recovery Wizard is designed for Mac OS X 10.5/10.6/10.7, it can recover photos, videos, music, documents, application, and any other data due to deletion, formatting. It supports SSD, memory card, memory stick and external hard drive.
Steps to recover SSD data:
Donwload the free trial to scan out your lost data and preview them one by one to check the quality before you pay for it.
Connect your SSD to the computer.
Then Install and run the program. Go to Quick Recovery, choose SSD to scan and then preview the files, if you can't find the lost data, please go back to the main screen and click Deep Recovery.
Deep Recovery uses RAW searching technology that scans your files sector by sector to make sure that all the possible files can be retrieved. It is highly recommended that you try this when other recovery module doesn't work.
Under Deep Recovery Model, you select SSD to scan then select the file type you want to recover, the scan process may take a little longer.
Preview the lost data and then decide to purchase the full version to recover.
If you are running Windows OS, please refer to EaseUS Data Recovery Wizard which is designed for Windows users.
