SSD-Z is a small and completely free tool for identifying hard drives, especially solid state drives (SSDs). The program displays all the most important information about the mounted media, allows you to check its technical condition, partitions and performance test. The application created by Anders Jakobsen is deceptively similar to popular CPU-Z and GPU-Z programs.

It has an almost identical, simple interface containing all the most important information. The main window displays the disk name, version of the used firmware, serial numbers, as well as information about the controller used, memory cells and technology of their implementation. Thanks to the program you can find out what functions the drive supports (e.g.

S.M.A.R.T., NCQ queuing), what interface it uses and what temperature it has, provided that the manufacturer has equipped the drive with a suitable sensor. The application also allows you to check the status of the TRIM function responsible for informing the disk about the possibility of releasing a specific sector and thus better management of the records made on the disk. The program is divided into tabs, the second tab contains diagnostic data from the S.M.A.A.R.T.

mechanism to determine whether the drive is working properly. The author has also equipped the application with a list of partitions, which contains information about their capacity, displacement, as well as the exact designation. SSD-Z takes into account the over-provision area.

The program has a built-in simple tester. It allows us to check the performance of 4512B, 4K and 128K samples in both random and sequential operations. It is also possible to check the time of access to the data.

SSD-Z is available for free and does not require installation on a computer (operates in portable mode). Supports SSDs, HDDs, removable media such as flash drives, as well as optical drives. The programme interface is available in English.
