The Endurance Rating (140 TBW) is calculated using Global testing standards, however, Intel® SSD's are expected to exceed those values in almost all cases.
The Media Wearout indicator is a more realistic indicator of the wear of the chips. It declines linearly from 100 to 1 depending on the number of cycles the NAND media has undergone. If the normalized value reaches 1, it means that the average erase cycle count has reached the maximum rated cycles. Although, it is likely that significant additional wear can be put on the drive, as is in this case.
The SMART counters for the previous attributes are based on writes and expected endurance, however, if the drive is healthy and free of errors, it should work well beyond those thresholds.
The Available Reserved Space reports the number of reserved blocks remaining; this is related to over provisioning. This value will decrease if the reserved space is used. In this case, the SSD still shows 100 percent availability of the reserved space.
There are some SMART attributes that are direct indicators of possible issues in the SSD components or functionality. These vary for each SSD series. For the Intel® SSD DC S3500, it would be advised to contact the Support Center if you notice a continuous increase in the following attributes: Re-allocated Sector Count, Program Fail Count, Erase Fail Count, Power Loss Protection Count, End-to-End Error Detection Count, Uncorrectable Error Count, CRC Error Count.
THX for the quick reply and the explanation of the SMART attributes!
One question is still left:
* Is there a way/program to monitor the SMART attributes and get notifications on errors/wear out?
To give you an example, I have written a Nagios/Icinga plugin to monitor SMART attributes:
The plugin uses it's own JSON database to interpret the SMART attributes and return WARNING/CRITICAL if
some values of the attributes reach a certain threshold. I have used your SSD specifications to interpret the SMART
Obviously this is a custom solution for Nagios/Icinga, is there a standalone daemon/program to monitor Intel SSDs?
All the best, Georg
We have two software applications that can be used to monitor and manage the Intel® SSD DC S3500. These are available from the Intel® Download Center for the Intel® SSD DC S3500.
- Intel® Solid-State Drive Data Center Tool: is a CLI application available for Windows* and Linux*. It is a drive management tool for Intel® Solid-State Drive Data Center Family of products, it works for both Intel SATA and Intel PCIe* drives.
- Intel® Solid-State Drive Toolbox: is a Windows* application mainly used for mainstream consumer SSD's, and also with the Intel® SSD DC S3500 and S3700 Series.
These tools are not designed to run or notify automatically when a threshold is reached or exceeded. You would have to monitor the SMART attributes of the Solid-State Drives manually, or use 3rd party software to add them into your system routines.
The report will inform if any of the attributes is abnormal and requires attention. When this happens, you should contact the Intel Customer Support in order to determine if further actions are required.
