[SOLVED] Formatted vs Unformatted SSD/HDD Read/Write Speed

[Ahmed.K]

Is there any effect on the speed of a Unformatted and Formatted SSD?
What if it has one of the following: 3D NAND or NVME or a M.2 SSD or just Normal?
Is there any effect on a HDD also?

you need to format it to use it.

"Formatting" is pure OS thing, The only things SSD knows is "read a sector, erase a secror, write a sector".

From OS perspective: File systems do have an overhead, so yes, there would be a performance hit when I/O is done on file and not on physical media. Many database servers have option of using "raw" space for storage instead of a file system.

Without out it be formatted, how would you plan on accessing it?

Mostly irrelevant. Outside of a few specialized use cases (db server mentioned above), the drive needs to be formatted to use.
And those db servers have their own overhead.
