Impact factors

The following variables can be completed

density

if manufacturer is given, density can be retrieved from a fuzzy matching on our ssd repository. If several ssd matches the given manufacturer the average value is given and min and max value are used as min and max fields.

Manufacture impact

For one SSD the embedded impact is:

\[ \text{SSD}_\text{embedded}^\text{criteria} = (\text{SSD}_{\text{capacity}} / \text{SSD}_{\text{density}}) * \text{SSD}_\text{embedded_die}^\text{criteria} + \text{SSD}_\text{embedded_base}^\text{criteria} \]

with:

Constant Units Value
\(\text{SSD}_\text{embedded_die}^\text{gwp}\) kgCO2eq/cm2 2.20
\(\text{SSD}_\text{embedded_die}^\text{adp}\) kgSbeq/cm2 6.30E-05
\(\text{SSD}_\text{embedded_die}^\text{pe}\) MJ/cm2 27.30
\(\text{SSD}_\text{embedded_base}^\text{gwp}\) kgCO2eq 6.34
\(\text{SSD}_\text{embedded_base}^\text{adp}\) kgSbeq 5.63E-04
\(\text{SSD}_\text{embedded_base}^\text{pe}\) MJ 76.90

Info

If there are more than 1 SDD we multiply \(\text{SSD}_\text{embedded}^\text{criteria}\) by the number of SSD given in units.

Usage impact

Only power consumption is implemented.
