Yes, I see: this is not a technical site (with technically correct formalism), but a consumer oriented site, with consumer-oriented lack of formalism.

no one uses GiB/KiB/MiB on any site that i am aware of. it is unnecessary for the purposes of general reviews.
Usually only people who like to argue bring this up….this sounds like someone i know ;o

As much as we appreciate your clarification, this SSD is greared towards the consumer who would not understand such. For simplicity sake, each module has a capacity of 32GB (gigabyte) which totals 256GB. Over provisioning and firmware reduce that to the advertised 240GB. In my own opinion, the units of GiB and GB are an absolutely unnecessary distinction which only serves to cloud something that is a very simple and clear explanation.

As usual, the capacity figures are based on ignoring the distinction between gigabytes (power-of-10 units) used by storage vendors and gibibytes (power-of-2 units) used by chip vendors and operating systems.

In particular the advertised capacity is 240 gigabytes, but MS-Windows reports capacity as 224 gibibytes, which is the same. The NTFS formatting has a small overhead that does not change the outcome significantly.

The analysis should be:

* The raw capacity of the chips is 256GiB (which is 275GB), as there are 8x 32GiB flash chip modules.

* Over-provisioning accounts for around 14% of total capacity, leaving 240GB (which is 224GiB) as the visible volume capacity.

The tell is in your CDM 4K single command numbers. I’m replying to your email now. I just walked in the door.
