How many bits is written at a time to my drive?

[Oblivion77]

Hello everyone

Whenever I make an action, save, change etc. a file:

How many bits is written by the writing-head to my HDD at a time?
Does it write several bits simultaneously, or only one bit at a time, until the whole action is written?

I have the same questions for SSD and the flash-memory function?

I have only been able to find something about writing speed

Thanks a lot in advance for answering

One bit at a time in had.
But SSD writes many bit at a time.

Do you have specific numbers?

Anyone else wanna contribute with more knowledge?
Thanks

It really depend on spindle speed and writing head speed and frequency at which it writing.

So some HDD's can write more and 1 bit instantly, or still only 1 bit at a time?

Considering; the average write of a 7200 RPM Drive is a about 350MB/S and average SATA Drive is close to 1500 MB/S the M.2 SSD is even higher (dont know the number by heart sorry)

since 1MB = 8000000 bits
so it give use 350MB/S = 2.8000E+9 bits/seconds for HHD, and 1500MB/S = 1.2000E+10 bits/Second for SATA SSD.

so instantly speaking a bloody large number of "bits" per moment

I dunno what does it good for you to know, all most people care and know about is the average r/w random/sequential speed.

At the r/w head for example, if multiple platters, multiple heads, several bits can be written at a time, BUT SATA is SERIAL? that mean one bit at a time there, but these systems run at different speeds.

1 'bit' at a time.

But, consider 2 typists.
1 types at 5 wpm, with lots of mistakes.
1 types perfectly at 80wpm, with no mistakes.

They each only type 1 character (bit) at a time.

Arif said in the beginning, that SSD's could write many bits instantly.
Can anyone clarify, or is it still only 1 bit at a time?

Thank you

Well, its a bit more complicated than that.
