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
