Flash drives, which also write to microcircuits, are fundamentally different from OCZ and Kingston SSDs in that the latter have a TRIM interface command. It forces the solid state drive to physically clear Data Recovery blocks of any information after deleting a file. 

Nevertheless, instantaneous destruction of files with OCZ does not occur – after the appropriate command is received, data blocks are cleared only after a certain time period , although it is impossible to predict which one.

The algorithm of the TRIM command :

The TRIM command is aimed at maintaining a constant high performance of devices, but if the disk managed to complete it, then it can be almost certain that the deleted data was completely destroyed and cannot be recovered. However, TRIM is not performed in all cases, therefore, Twitter data from the drive can be restored in the same way as on the HDD.

You can effectively extract data from OCZ and Kingston SSDs in the following cases:

  1. Older OS versions from Apple prior to OS X 10.10.4 did not support TRIM for any third party SSD;
  2. TRIM does not work in older versions of Windows either, so if you have XP or Vista installed, then recovering deleted data from OCZ will not be difficult;
  3. USB and FireWire protocols also don’t work with TRIM, so retrieving information from external SSDs will not be difficult.
Data Recovery

And another situation in which files from a solid state drive are not deleted by the TRIM command is file system crashes and disk corruption. In this case, you can scan it, for example, with the Hetman Partition Recovery application and extract all the necessary documents, images, etc. from it without any problems.

With the recovery of deleted files with this application, even beginners should not have problems thanks to the built-in wizard, which explains the sequence of actions to the user in a step-by-step mode.

When Hetman Partition Recovery is opened, a list of all installed in the system and external drives will be displayed in the central window. This lists each disk, its size, file system, and used space. Even damaged devices are displayed that are not detected by the system in the “My Computer” section. They will be displayed as unallocated areas with full size. This makes it easy to select a failed Kingston SSD and start data recovery.
