How to Figure Out the Actual Capacity of SSD?

In addition to the processor, when purchasing a mini PC, everyone also pays attention to the capacity of RAM and SSD. Now, let us elaborate the definition of SSD.

The capacity of an SSD refers to the maximum data storage capability of a solid-state drive. This pertains solely to the user-accessible storage and excludes non-volatile memory segments designated for the flash controller's operation.

Next, we should understand the unit conversion for SSD capacity.

1GB=1KB*1M Bytes

1M=1KB*1K Bytes

1KB=1KB*1Byte

1GB=K*K*K*1Bytes=K3*1Bytes

Furthermore, the SSD manufacturer adopts a convention where 1KB is equivalent to 1000 bytes, whereas the operating system supplier defines 1KB as 1024 bytes. As a result, the difference between 1GB based on these two definitions amounts to 10243/10003, approximately 0.93.

Therefore, the storage capacity displayed within the operating system results from multiplying the indicated SSD capacity by 0.93.

Then, the actual capacity of 128GB is 128GB*0.93=119.04, around 119GB

256GB is 256GB *0.93=238.08, around 238GB

512GB is 512GB *0.93=476.16, around 476GB

1024GB is 1024GB *0.93=983.04, around 983GB

2048GB is 2048GB *0.93=1904.64, around 1904GB

4096GB is 4096GB *0.93=3809.28, around 3809GB
