How to find SSD failures – SMART


Solid state drives, SSDs beats more and more the traditional hard drives from the top. But they aren’t so perfect as they seem.
One example – A SSD got only a certain number of writes before individual cells get damaged. But there are ways to check-up SSDs see problems before they happen. The magicword is SMART-SelfMonitoringAnalysis and ReportingTechnology.

SMART wrights a sort of diary for the flash drive, in which you can see for example how strong individual cells are already damaged. How to get to this „diary“ is explained in the following.

Who needs a specific tool for a SSD from a manufacturer can download it in the most cases from the website of the manufacturer. In the case of Samsung for example it is the software „Magician“.

Ofcourse you can get tools by other developers in the internet. But this tools aren’t in most of our tested cases so precise like the tools from the manufacturer themselves.

The allround SMART tool

This tools are not only to test SSD’s. With this tools you can make even improvements of the operating system. These optimizations are then adapted to the SSD which enables the operation to be possible. Moreover, such a program can also be quite handy as a firmware update tool for the solid state drive​​. Who needs more detailed values have to look in the RAW values. This document gives you informations about the read and write errors, the data written to the volume, the number of hours and the temperature of the SSD.



If you don’t want an access to only stored data and also to actual informations you have to do a „short self-test“. Here the software will do a hardware test randomly and give you a short analysis. The most important parameters are explained here:

Raw Read Error Rate

Reading failure rate

Reallocated Sector Count

Outsourced datas in spare sectors

Power-On Time

Number of operating hours

Program Fail Count


Erase fail Count



Workingtemperature of the intern sectors

CRC Error Count

Number of SATA interface encountered errors

Media Waereout Indicator / SSD Life Left

Indikator für Flash-Abnutzung

Host Writes / Total LBAs Written

Indicator of Flash falures

Host Reads / Total LBAs Read

Counts the total amount of data reading in sectors
