Questions about M2 SSD

[Antoine]

So I know usually when you get a hard drive its actual space is not as advertised, for example a hard drive listed as a 4tb hard drive actually turns out to be around 3.6tb

A friend of mine just fgot the newly released Firecuda 530 M2 Gen 4 PCIe SSD and when its in his system it shows the total storage as 4tb (its a 4tb drive) instead of 3.6tb. Do SSDs not take out that additional space like the traditional hard drives do?

you may be referring, or seeing the effects of, GB versus GiB.
in modern years, drive capacity is in base 1000 (or base 10) instead of what you may expect it to be, that is, base 1024 (or base 2), as in what the OS uses.
so a GB is 1000MB and a GiB is 1024MB.
or in current world examples, 1TB as advertised on the box comes out to be .91TB when shown in the OS.
it all depends on how manufactures want to advertise their specs.

thats not what Im asking. So Im gonna use the same thing you said as an example. As you said 1tb as advertoised comes out to 910tb when shows on the OS, which is how its supposed to work. My friend got an m2 gen 4 pcie SSD which was advertised as 1tb (its really 4tb but Im using the number you used to make my example easier) and on his OS it shows as 1tb (instead of the 910 tb I would have expected it to show) so I was wondering if that was normal, cause I expecvted i t to show 910tb (like you said) but instead the OS showed the full 1tb

Is the drive formatted? If so what file format is it using?
What does diskpart show?
Was the drive purchased from a reputable store/seller?
Was the drive cheap compared to other drives?

Its using either Exfat or fat32 (most likely exfat since its 4tb)
Dunno where it was purchased
Its the newly released Firecuda 530 4tb it was $1000 so it definitely wasnt cheap lol

Are you using the drive in a PC or Game console?

Are you using the drive in a PC or Game console?

theyre using it on a game console. But even when on a game console traditional har ddrives and use external hard drives show less storage that advertised (i.e all the internal and USB external Hard drives Ive had in every console Ive owned, were 8tb drives but the consoles OS displayed them as 7.6tb) so I would think the console part shouldnt matter if they all treated other drives as expected, so thats why Im wondering if the M2 SSDs are different?

[Bastet]

Which console is it?
If PS5 do they have the latest OS installed which adds the feature to use a second HD or are they using the beta version?
If another console is the OS up to date?

theyre on the PS5 and yes they have the latest update which allows M2 SSD support, they werent in the beta so its not the beta version

[Bastet]

The size may be unique to the console.
When the SSD was added did the PS5 detect the new drive & ask to format it?
As yet I don’t require any extra SSD for my PS5 so cannot test this.

My friend got an m2 gen 4 pcie SSD which was advertised as 1tb (its really 4tb but Im using the number you used to make my example easier) and on his OS it shows as 1tb (instead of the 910 tb I would have expected it to show)

to me, this simply shows that the advertised capacity was in TiB, the same as the OS uses, hence the same figure from both sources.

but maybe I’m missing something. :unsure:
