Your hdd has a temperature of 44°C and had a maximum temperature of 
55°C. The two 100 values are SMART indicators which describe device 
health. Normally a value of 100 means excellent condition.

The columns from left to right:

- SMART attribute id (194)
- SMART attribute name (Temperature_Celsius)
- SMART attribute flag (?)
- SMART indicator current value (100). This normally is a relative value.
- SMART indicator worst value so far (100). This normally is a relative 
value.
- Threshold - when the indicator value is lower than this value, the hdd 
needs attention.

Some attributes need different interpretation on different drives. My 
has the following attributes for temperature:

194 Temperature_Celsius     0x0022   037   055   000    Old_age   
Always       -       37 (Lifetime Min/Max 0/19)

Current and worst values indicate current and highest temperature so far 
on this drive.

By the way - the temperature is so low, because the Mac has just been 
booted.
