This happened up to 3x as well
i needed 2 other ones to gather the screenshots
it's every time this way
Can't be acceptable, can it ?

>Can't be acceptable, can it ?
no
i have no idea why this would happen though, in operation usb devices should use either 3 or 2, not switch in the middle of operation

are you sure that it's actually switching to usb 2? maybe it's just throttling.

it never went up again.
Additionally, with 50GB free space,
at around the halfway mark i get an error i don't have enough free space on my hd
which i do . .

That's not USB switching to 2.0. That's just IO caching.

this is completely normal you stupid fuck
no it isn't switching between usb 2 and 3 the controller or flash is running out of cache

>zomg my ssd went from 1gb/sec to 200mb/sec after 8gb
>did it spontaneously switch from nvme to sata

your question requires intense thinking

are you fucking retarded?
most of the time it ist just the cache thats pretty fast

>my macbook switched from 4 ghz to 800 mhz, is it possible for a i7 to spontaneously switch to pentium 3?

If this is so normal then what is the goddamn point of having 3.0 over 2.0 ??

Having *potentially* faster drives. Just because you cheaped out on your shit doesn't mean everybody will.

It's a €700 laptop,
Intel core i3-7100 CPU 240GHz
I've donw this a dozen times and never had this before...

*2.40 GHz ofcource

Post the oRly screenshot

I meant the flash drive

This. In their infinite wisdom, they decided to show what had been sent to the cache rather than how much had actually been written. This means that even shitty drives will show massive write speeds initially and then plummet to their real speeds when said cache is full.

It's called caching my friend. This is perfectly normal.

You wouldn't be getting 30 megabytes per second with USB 2, friend.

No.
Also didn't know there were Dutch people as dumb as you.

you kno m

It happens because most modern OS's have a cache for file transfers and will drop down the the speed it can handle. It normally is big enough that your day to day operations won't feel sluggish and will save the data at specific intervals. They do this to prevent disk corruption. There is even a command in Linux to force a flush to disk.

So OP the issue is you have a bottle neck somewhere, maybe the USB drive is not a proper USB3 drive. Have you tested the speeds in a 2nd PC?

So you just decide to completely ignore the parts where i mention i transfered files this way 12x before and this Never happened
SO yes, it's truly a usb 3 port. They were bigger files, too
or
> saving the data at specific intervals
it's a one time permanent drop in speed, after 5 seconds

After all this, OP is still exactly as retarded as before he made this thread.

Write caching is catching up either at the device side of things or at the operating system side of things, if it's the usb side of things the device may be on the way out if it's the operating system side of things the files you are transferring may have a lot of page misses or not be caching correctly - can happen with large files that do not wish to page into write cache. Windows write cache is very asburgers and can be amazing or stupid like this sometimes.

Yes, he would.

You can get up to 60 MB/s actually. It would generally be between 40-60 MB/s.

two possibilities that happened here
1. the easy to transfer stuff went by quick, while the harder to transfer stuff went by slow
2. your storage medium went out of cache, which slows transfer rates significantly

obv bait is obvious

Yes. I stole one of your USBs so now you only have 2 left.

Lel

i9 becoming an i7 is a thing though.

Not an apple laptop, faggot

read what is cache idiot

are you challenging me to a duel !!?/
