In recent times, the use of new storage drives as an alternative to hard drives has become widespread: these are SSDs or solid state drives. Unlike conventional data recovery hard drives, SSDs lack moving components, such as magnetic platters, reading heads, or motors. The only element that SSDs usually have in common with conventional disks is the electronic controller and also, in most cases, a connection interface such as SATA. SSDs are based on flash memory technology. USB sticks and SD cards, storage devices that are already part of our daily lives, also work with this technology.
How do SSDs outperform conventional hard drives?
It can be said that the main advantage of SSDs over conventional hard drives is their speed of response. Conventional discs need to invest a considerable amount of time in getting up and running. When starting, the engine must start turning to move the plates until it reaches the optimal speed; the reading heads must leave their parking area and move until they are positioned correctly. Then, for each read or write operation, the heads must wait for the rotation of the plates and position themselves in the appropriate sector.
However, on an SSD disk, by working exclusively with flash memories, the reading or writing of Twitter data is much faster. It is also much shorter the time it takes for the disk to activate and be ready to work, almost instantaneously.
Pros and Cons of SSDs :
There is no doubt that SSDs have a much better performance, and that without a doubt, in the not too distant future, they will gradually replace conventional hard drives in a good part of our computer equipment. But not all are advantages with this type of devices, being the price and capacity its main disadvantages. An SSD is much more expensive than a conventional disk of the same capacity. In addition, the maximum capacity that we can find today in the market for SSDs, is much lower than that available in conventional disks.
It should also be mentioned that certain SSDs are known to suffer defects in their firmware or controllers; these failures can leave the disk unusable and cause us to lose access to our data. On the other hand, most SSD models are programmed to “clean” (permanently erase) the free space that remains unused in the file system. This has serious implications if there is an accidental deletion of files or folders, or before the disappearance of them due to a logical error. In those cases, we run a high risk of the disk deleting any remnants of the deleted or lost files, causing their irretrievably lost.
What to do in case of data loss :
If you know that your computer uses an SSD disk and you are in a situation of file loss or accidental deletion, we recommend that you immediately turn off your computer and put your SSD in the hands of professionals to carry out a Data Recovery. If the computer is still on – either because it is working with it, or because it is trying to recover the data at home – for each minute that passes more information will be irretrievably erased by the device itself, making it impossible to recover the data even by professionals.
This particularity of SSD drives can be considered a good security measure by those who want their deleted or old information to be recovered by anyone, but it can also represent a big problem in case of loss of information by accident. We end by remembering, as always, that the best prevention is to have one or more backups, updated and checked, so as not to find ourselves in the need to request a data recovery.
