Impact factors
The following variables can becompleted
density
ifmanufacturer is given,density can be retrieved from a fuzzy matching on our ssd repository. If several ssd matches the givenmanufacturer the average value is given and min and max value are used asmin andmax 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 | 73.98 |
Info
If there are more than 1 SDD we multiply\(\text{SSD}_\text{embedded}^\text{criteria}\) by the number of SSD given inunits.
Usage impact
Onlypower consumption is implemented.
