SSD are Disk objects of type SSD.


Name Unit Default value Description Example
units None 1 SSD quantity 2
usage None See Usage See usage ..
type None SSD "SSD" SSD
capacity Go 1000 Capacity of a ssd disk 500
density cm2/Go 48.5 cm2 per Go on a ssd wafer 48.5

The following variables can be completed


if manufacturer is given, density can be retrieved from a fuzzy matching on our ssd repository.

Manufacture impact

For one SSD the manufacture impact is:

\[ \text{SSD}_\text{manufacture}^\text{criteria} = (\text{SSD}_{\text{capacity}} / \text{SSD}_{\text{density}}) * \text{SSD}_\text{manufacture_die}^\text{criteria} + \text{SSD}_\text{manufacture_base}^\text{criteria} \]


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

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

Usage impact

Only power consumption is implemented.
