Read temperature of the Intel 750 SSD

[Stefan1024]

I meant Crystal Disk Info, not Crystal Disk Mark. Good luck!

All tools do not show a value for the temperature or do not recognice the drive at all....

"Log identifier C5h"
I am wondering if this is describing one of the SMART logs that is found on more recent drives. If it is, you can check out smartmontools (found on most Linux distributions) along with the following command:

smartctl --log=scttemp /dev/sda
(where /dev/sda is the first storage device, sdb is the second, etc.)

-l TYPE, --log=TYPE
scttemp, scttempsts, scttemphist - [ATA only] prints the disk temperature information provided by the SMART Command Transport (SCT) commands. The option 'scttempsts' prints current temperature and temperature ranges returned by the SCT Status command, 'scttemphist' prints temperature limits and the temperature history table returned by the SCT Data Table command, and 'scttemp' prints both. The temperature values are preserved across power cycles. The logging interval can be configured with the '-l scttempint,N[,p]' option, see below. The SCT commands were introduced in ATA8-ACS and were also supported by many ATA-7 disks.

I do not have a 750 SSD to play with, but I will try it out on my 520 when I get home because I know for a fact that the 520 does not report temperature via SMART attributes.

There is a Windows port of smartmontools on SourceForge, but I have not been successful getting it to work at this time. (Retrieving SMART logs requires admin privileges, but for some reason the program cannot identify the drive in admin mode) (EDIT: See below. Somehow my work computer did not like smartmontools.)

Anyway, that is what I think Intel is describing in the documentation. Perhaps you can find a more user-friendly program that can read SMART logs, and not just SMART attributes.

 

 

EDIT:

OK. Here is the sample output when I run it against my Intel 520:

I am not sure if I can trust this information. I know my SSD had been subjected to a more varying range of temperatures than just "30°C" for the past 2-3 years... I hope your 750's temperature logs give you more useful information.

Thank you for the input.

 

Well I'm pretty sure C5h (=197) is the number of the first register or index where the data is written to, but I have no idea how the get the raw data of this block.

 

Anyway I used smartmontools to test my Intel 750 and I validated the results with the readings of my 850 Evo in M.2 format.

 

850 Evo results:

The current temperature and the power cycle min/max temperature sounds reasonable to me. It goes up in stress tests and is the same as reported with Argus Monitor. Just keep in mind the power cycle temperatur is only sampled once every 10 minutes.

The lifetime min/max temperature however is 0°C/70°C ,what is the same as the allowed temperture limit. Perhaps they stressed the drive to this limits in the factors for quality controll.

 

 

Intel 750 resluts:

The tool was only able to read a very restricted amount of data from the drive:

"C:\Program Files (x86)\smartmontools\bin\smartctl.exe" -A -f brief C:\smartctl 6.3 2014-07-26 r3976 [i686-w64-mingw32-win8(64)] (sf-6.3-1)Copyright (C) 2002-14, Bruce Allen, Christian Franke, www.smartmontools.org=== START OF READ SMART DATA SECTION ===Current Drive Temperature:     41 CDrive Trip Temperature:        102 CType <return> to exit:

But at least it shows the current temperature!

When I will get the thermal image camera I will validate the value.

For what it's worth, when I run the same command against either of my SM951 NVMe drives I get no output values at all, unfortunately.

Well I guess thise new PCI-e NVMe dirves uses a new protocoll and the software is not updated yet.

Yeah, we can only hope things will improve in the future. This is the full output I can get right now:

SMART support is:     Unavailable - device lacks SMART capability.

I do get quite a bit information there. Also the Intel 750 does support SMART and the SM951 not (or it is disabled).

That is way you can't read any of the attributes since the software does rely on the SMART protocol to do so.
