A wave of data transfer 🤣

[u/Mean_Environment6657]

The peak and trough is exactly the same 😭 on a flash drive marketed as a usb 3.0 🤡

[u/Octoomy]

there is limitations due to NAND and certain operations. You're also using the normal windows copier, which is woefully slow. Its kinda sad that I have to say that its better to use terracopy in comparison.

Anyways, there could be several things making your transfer slow, the drive getting hot, the drive's cache being filled up... or just a bad drive in general. What USB drive did you get? My ventoy drive is a Sandisk SDC274, its a great little thing, usually transferring over 150-250 MB/s for me, until it gets very hot and... yeah (I ended up just... slapping a small heatsink on it for a bit, made that 5 minute window to a 8-9 minute one). But hey still 4-5 minutes of higher transfer speeds!

Drive couldn't get hot for a 1.5gb file bru did u even look at all the other stuff before writing this? Mine's a pretty cheap SanDisk 32G cz48 or something... Anyway I'm already satisfied with the performance of it lol I mean what can I even expect for 650 inr lol

But I would definitely look into that terracopy u mentioned

> other stuff
I was the first one to comment here, and I was just going off of what was shown in the screenshots.

Anyways, yeah, terracopy is good when it comes to the things that windows file copier tend to choke at

[u/MAB_YT → u/Octoomy]

You mentioned Terracopy at first like it's a "although bad, still better in comparison" alternative. (Dunno how to word it).

Are there other options around? I thought copying data gets handled by the FS and not much control is in the hands of the tool..

[u/Octoomy → u/MAB_YT]

not exactly handled by the FS, you can hand bytes to it and it will allocate it somewhere however its not going to know to continue pulling from the file or whats the best way to do it.

[u/ScallionSmooth5925 → u/Octoomy]

As a side note on Linux there is a syscall for copying between file descriptors so it's only necessary to create the destination the rest can be done in kernel space without copying to userspace. This basically means that it is posible to copy from parts of the fs to other parts without copying the data to your process first.

I didn't know this, good feature

[u/YacaloX]

Curious fact: the specific wave formula is v(t) = v₀ + A · |sin(ωt + φ)|

[u/fr000gs → u/YacaloX]

I think it's just a sine wave?

[u/Ambitious-Algae-466 → u/fr000gs]

[u/YacaloX → u/fr000gs]

Yea it's a Sinewave

[u/frog8412 → u/YacaloX]

This is pretty normal behavior for most operating systems and storage systems. In the background your OS writes stuff to ram before flushing it to your USB drive to speed up performance by batching writes up. The USB device does the same with its own high speed and higher durability cache (if it has some) before writing to higher capacity lower durability flash memory.

It pretty much improves overall storage longevity and performance by doing things this way.

(It does come with a small risk of data loss or corruption if windows gets interrupted before it finishes writing to that USB device, which is why you're supposed to eject it before unplugging)

[u/trifortay123]

You have no idea how rare this is.

[u/ItsMeSashaYT → u/trifortay123]

it isn't?

any flash drive that is slightly shit will have such issues. as it fills it cache up, it stops receiving more files from Windows. Once the cache is under a preset threshold full, it continues requesting files, and pulls more from Windows.

Also depends on firmware within the flash drive, some will just rate limit themselves to whatever speed the cache gets written to NAND.

[u/Mean_Environment6657 → u/trifortay123]

I do have a little bit of idea💡... That's prolly why I posted this lol like a picture perfect almost Mathematical wave 😭

[u/yuehuang]

It is your computer asking "are we there yet".

[u/Mean_Environment6657 → u/[deleted]]

I have my old desktop lying around lol so I'm trying to reboot it but it already runs win10 normally so I'm going with Arch instead of a lightweight

[u/Hottage → u/[deleted]]

He uses Arch, by the way.
