There does not exist any silvery bullet that will kill your drive nor there exist any magical potion to protect it! As your SSD drive ages, the wear and tear of the electrical components happen and in due course of time, leads to the failure of the drive. It is as simple as that!
When the SSDs initially hit the computer market, they were known for both good speed and great reliability. A large percentage of the users were of the view that, since the SSD has no such mechanical parts, so it is at a lower failure risk with a simple logic that – with lesser number of parts, the chances of parts breaking is also lower and so overall reliability is superior. In case of SSDs, however, this reasoning does not always fit, as data losses happen with SSDs too.
How an SSD Drive Fails ?
Solid state drives, the SSDs, in a way, do not have to worry about the wear and tear of the mechanical parts, but still, they need to worry about the wearing of the electronic parts. Fresh drives are far less likely to fail than the older ones. It is really very true that their flash memory surely wears out in due course but the endurance that is there is far more than just adequate for a normal consumer use. You will be amazed to know that an SSD can last for over 10 years even if one writes around 100 GBs of data every day.
Data Loss on SSD
SSDs have no such revolving components, rather, an SSD has multiple NAND flash memory chips that are set and arranged in a grid, characteristically, in columns and rows. Issues like variations in power supply, random power fluctuations or failures, and forced shutting down of the system can cause SSD data corruption.
If there is an inaccessibility of data saved in the transistors of any one of the NAND flash chips, then, it can lead to a failure of data in other chips too and eventually, it can lead to the complete failure of the SSD.
A Practical Scenario
In a practical scenario, the SSD had lost its data when it was left without power for 7 days. An executive had to give a presentation who gave this statement that the data on an SSD is restored and is divided to half for every 5 degree Celsius temperature rise in the place where that SSD is saved. The problem in this very case was JEDEC slideshow detail. The JEDEC had written the data to the SSD at a high (55 degree Celsius) temperature and after that it was saved at a lesser temperature of 40 degrees Celsius on some old SSD which had lot of wear and tear and after that it was then left unpowered for almost 3 months. The scenario is an absolute one, it is in fact the worst case scenario under which if we write data to an SSD at a low temperature, and then save it at a higher temperature and then it that SSD is near to its end of shelf life, then it is left unpowered (which is a thing that can never happen in a large datacenter as the servers over there run 24X7), then chances are there for data loss.
Recovery of Data from a Failed SSD Drive
Restoring data from an SSD drive can best be done by a third-party tool. These tools are thoroughly professional and their performance in recovering SSD data is tried and tested. SDD data restoration becomes a cakewalk if you fetch the right and apt tool for this purpose.
