Transfer speed not as what I expected (new update !)

[FalconWingz]

So I have a normal internal Harddisk, which usually will get up to around 100mb/s

and i have a WD external harddisk, which also get up around 100mb/s.

 

both is connected to usb 3.0/3.1

 

but when transfering data, windows only telling me that the speed is only 30-40mb/s

why is it ?

30-40mb/s is usb2 speed. start by checking that your usb3 drivers are working.

 

further to this, what kind of data are you transfering? linear, non fragmented data or random, fragmented data? that makes a big impact

yes my usb3 drivers are working and updated, i checked here

mostly im transferring alot of footages/clips, around 500 or more videos.

is the external drive USB 3 though? both ends need to support it.

Types of files will impact this significantly, Large files will have a larger transfer speed, lots of small ones will slow it down considerably.

Depending on the size of these files this is why it is slow, transferring a folder with 12 large video files I was transfering at 170MB/s, now with a folder with all sorts of files like, Videos, Pictures, textures, mp3s, models, is ranging from 1-100MB/s.

Here's the recent transfer that I do.

 

 

it consist of 30GB of 76 mp4 files.

 

 

 

the speed is only 66.8 MB/s

The file is from my WD harddisk (usb 3.0) to my WD my book (usb 3.0)

which doesnt explain why the speed doesnt reach the usb 3.0 max speed

I never got above 100mb/s transfer speed

Drives read and write slower depending on where its being placed on the other side..

Also where it comes from..

 

You could very well be copying files to the end of the drive......say parts here, parts there.......or reading originally from a slower or fragmented  section,... without it ever letting you know where its taken from on the drive itself..

 

Either of these from either drive.. Will slow the process down.

76/30, roughly 2.5GB per file, would probably make a smooth transfer, however I'm assuming since they're from a camera, the sizes differ greatly. 

There's nothing wrong with your performance, it's transferring from external to external.

So they're both external??? a harddrive is a harddrive, if you've connected to it with USB, don't refer to it as an internal drive.

 

nothing seems wrong, file size variance fucks with transfer speeds, especially with external drives. you're operating within norms. If you want faster transfer, keep large and consistent file sizes.

Just because it CAN get that high, doesn't mean it's supposed to always be that high.
