solid state drive (SSD) capacity
SSD capacity is the maximum amount or data that can be stored on a solid state drive.
According to JEDEC, SSD capacity
should be defined as user-addressable capacity and not include non-volatile memory
areas intended for the flash
controller's use. JEDEC recommends that SSD capacity be calculated using the
following formulas:
For a logical block size of 512 bytes:
User-addressable logical block count = 21168 + (1953504 x SSD
Capacity in GBs); or
SSD Capacity in GBs = (User-addressable logical block count -
21168) / 1953504.
For a logical block size of 4096 bytes:
User-addressable logical block count = 2646 + (244188 x Capacity
in GBs); or
Capacity in GBs= (User-addressable logical block count -2646) /
244188
