While Hard Disk Drives are more common, Solid State Drives are also becoming more prevalent in many computing devices. The main difference between HDDs and SSDs is that HDDs use magnetic recording while SSDs use electronic recording to store data. HDDs use aluminum or glass platters which are coated with a super thin magnetic alloy while SSDs use a NAND flash. As such because SSDs don’t have any mechanical parts, they are less prone to failure and therefore more reliable.
However, SSDs do also fail. Reasons for failure may include; system corruption, electronics failure and environmental influences. When SSDs do failure, sometimes they may go with very important data you are not ready to lose. This could be bad news because since they are relatively new, they are no defined ways of recovering data from them such as is the case with hard disk drives.
Although there is not much you can do to recover data in your SSD, there are several data recovery software you can use from various vendors although there are no free options at the moment. This software may help you recover your lost data but the prognosis could be worse if your drive uses TRIM. This is because TRIM organizes your data for easy and quick access with a downside of aggressively deleting your files in case of failure.
For complicated cases where you are unable to recover the lost data by yourself, you may want to use a data recovery service. These are even more expensive that it would be advisable to forego them if such data is not absolutely important. If you really need that data you could start by calling your SSDs manufacturer and they could recommend a data recovery company they work with.
In practice, data recovery from a failed SSD could be expensive and difficult. Therefore you would want to safeguard your drive and take some precautions that could make recovery easier whenever your disk fails.
One tool you can use is for your SSD is S.M.A.R.T. This is a self monitoring system which looks for faults in your drive and detects when they are likely to fail. As such you can use the reporting tools of S.M.A.R.T to back up your data and prevent catastrophic loss when they fail. There are many other tools in the market you could use but the best practice is having a data backup plan.
In comparison therefore with their HDD counterparts, SSD drives are more reliable than the mechanical hard drives. This coupled with the difficulty and expense required in recovering lost data, these drives call for a more aggressive data backup plan for you to use them with ease.
