A question about data transfer/throughput speed

D

First off, hardware specifications:

The Fatal1ty Z97 Killer Motherboard \\ The I7-4790k 4.0 Ghz LGA 1150 Processor \\ Two 8 GB DDR3 1600 (CMZ16GX3M2A1600C10B) RAM modules \\ One 240 GB V300 SSD for OS, Boot, and program files \\ Two 1TB (WD10EZEX) HDDs in RAID 0 for mass storage, program data, and data that doesn't need As-fast access \\ and one 1TB (SB-ROCKET-1TB) NVMe drive for quicker access, downloads, and transfers.


Here's the "Problem":

Whenever I have a file I need off of the internet, I know that downloads aren't that fast (even with 100 Mb/s because of network throughput, goodput, etc.) but even when I'm transferring a file from a USB 3.0 drive to (or from) my SSD, or NVMe, the transfer rate is high for only a moment before speeds basically flatline. I'm not sure where, or what, the choke point here is so...

Here's The Questions:

I know there's a lot of variables here so any answer is a good one...

  1. Is there hardware I should be looking on replacing to fix my speed issue?
  2. If it's Not hardware, Is there a configuration setting that needs changed?

2a. Yes, I set the USBs to "Better performance"​

2b. I also enabled write caching which helped but not by much. Is it possible to increase the cache buffer? I'm also aware that each storage drive has it's own memory buffer, I'm still unaware if you can virtually increase that with RAM or not.​


I've been thinking about this for the last few months and I don't think there is a single right answer because of the many variables; So I'd like to hear everyone's ideas about this. Thank you.
