How to correctly find out the true volume of an SSD?

Question

Solid State Drives

I ordered a 360 GB SSD on aliexpress (still on the way) at a price like a 256 GB SSD or 120 in regular stores.
On the Internet, I saw comparisons / reviews only on the speed of reading and writing from this SSD, but no one checked the volume.
I think that the Chinese may well slip SSDs of a much smaller volume than it is written, because. with flash drives, they often do such "tricks". Yes, I know that in fact there will not be 360 ​​GB of free space, because. it seems like manufacturers calculate the volume based on the fact that 1 KB is 1000 bytes, not 1024, and in the SSD, it seems that 10% is reserved for something.
In general, how to correctly check the true / net volume of an SSD? I think you can use H2testw or HDD Tune to fill the SSD with data and already find out the real volume from the amount of data loaded, but will this damage the SSD drive (they also have a limited number of rewrite cycles)? Maybe there are better ways?

Answer 1

Well, if you live richly, you can afford it.

I think that the Chinese may well slip SSDs of a much smaller volume

They can, although it doesn't happen often.

manufacturers calculate the volume based on the fact that 1 KB is 1000 bytes, not 1024

A kilo is a thousand, so there can only be a thousand bytes in a kilobyte, no more and no less.

SSD seems to be 10% reserved for something.

Not necessarily 10% happens and 5% and 60% depending on the purpose of the SSD. But this does not affect the volume available to the user.

In general, how to correctly check the true / net volume of an SSD?

Burn a bunch of videos to disk and see how many fit.

but won't that damage the SSD drive

Of course it will hurt. Any use damages the disc, so in order not to harm it, it is better to store the disc in a cool, dry place. Several times a year, supply power for several hours, and in no case record anything.
And considering what kind of disk you have - such a volume of recording will most likely immediately disable it.

Answer 2

do not reinvent the wheel, you connect the SSD to the PC, the controllers will exchange information and you will get all the information through the diskmgmt.msc snap-in
