This is an mSATA SSD with a Silicon Motion SM2258XT My drive has one of four possible Flash chips soldered to the PCB, I don't know if other sizes are sold, at least I couldn't find any online. Please find attached the output of smartctl -q noserial -x /dev/sdX

I started looking at the csv files smartd generates and would like some help understanding it. On some websites ATA drives were said to show a 150 offset to the raw value in Celsius. A number 187 would translate to 187-150 as a value for degrees celsius. On some SCSI Enterprise drives the temperature is listed exactly in degrees celsius in the CSV file which is very convenient.

I found a few CSV files with strange output and would like to know how to find the correct decoding. Below is some data of ATA drives CSV output searching for then key 194 aka. Temperature_Celsius, showing the column number in which key=194 is found and the min and max value found in the next column that I think is the temperature.

For some drives the range can not be linear: minimal value 4, max value 253 would not translate by any linear offset assuming this is a digit and not hex. Also, min=55 max=79 is likely an offset of possibly 100? Pulling with smartctl shows 194 Temperature_Celsius 0x0022 073 046 --- Old_age Always - 27 (Min/Max 20/46)

key=194 in column=35 min=94 max=145 in /tmp/Temperature_Celsius.WD-WMC1T0306391.raw.csv (Model: WDC WD30EZRX-00DC0B0) key=194 in column=41 min=4 max=253 in /tmp/Temperature_Celsius.7SGEWP6C.raw.csv (Model: WDC WD80EFAX-68LHPN0) key=194 in column=53 min=5 max=43 in /tmp/Temperature_Celsius.Z840RT48.raw.csv (Model: ST8000AS0002-1NA17Z) key=194 in column=41 min=4 max=253 in /tmp/Temperature_Celsius.1SG60K6Z.raw.csv (Model: WDC WD80EMAZ-00WJTA0) key=194 in column=53 min=5 max=42 in /tmp/Temperature_Celsius.ZCT0EYFR.raw.csv (Model: ST8000DM004-2CX188) key=194 in column=41 min=104 max=250 in /tmp/Temperature_Celsius.JEGRVHKN.raw.csv (Model: WDC WD100EMAZ-00WJTA0) key=194 in column=53 min=6 max=42 in /tmp/Temperature_Celsius.ZCT0EQG7.raw.csv (Model: ST8000DM004-2CX188) key=194 in column=41 min=181 max=253 in /tmp/Temperature_Celsius.2YHZD7WD.raw.csv (Model: HGST HUH721010ALE601) key=194 in column=50 min=55 max=79 in /tmp/Temperature_Celsius.183584805068.raw.csv (Model: WDC WDS500G2B0A-00SM50)

Is there a magic table for each manufacturer to decode the smart output or syntax to log the raw value only? Btw: Google has not been my friend yet in finding an answer.

Due this bug, only 1 log entry gets correctly swapped, results in wrong values being displayed on big-endian platforms. For example:
