ReadyBoost on Win10; would USB3 provide real help in laptop video editing?

[ahhaa]

OK this is a question I'm working backwards from the one about using Premiere Elements... I've looked at the Xmas 'deals' out there and have found that most midrange laptops have a mix of USB 2 & USB 3 sockets- usually 1 USB 3 and 1-2 USB 2; but oddly some cheapos like the $299 HP 'Red Flyer' have 2 USB3s and one USB2.

Generally I'm looking at i5 machines and all laptops seem deficient in this critical area or another (like no HDMI out or sub-minimal max RAM). I didn't see anything standout in the refurbed arena, not even desktops (one guy was griping because he couldn't replace the non-standard PS.)

Anyway this question came up:

IF there were two USB 3 sockets (one & a hub won't work for data flow reasons) and one USB3 socket had a dedicated Readyboost flashdrive (an alternative could be a UHS-ii extreme microSD card)

THEN would this significantly help offset the shortage of RAM when using Premiere or Corel, etc?

I found an interesting article about Readyboost in 2016 here:

http://www.techrepublic.com/article/is-readyboost-still-an-effective-tool-in-windows-10/

but it doesn't have the answers I need.

I'm not wimping out, but I've just gone thru the most confusing issues about i5 CPUs, 2cores acting as 4cores, 4cores left unused by the software, and sellers trying to unload dogs at prices higher than 6 months ago...

Not likely. USB transfer speeds are slow compared to RAM. Unless something dramatically changed that I haven't seen, "Readyboost" offers little to help most users.

For example: http://www.howtogeek.com/123780/htg-explains-is-readyboost-worth-using/

In other words, don't plan on this as a replacement for RAM. Find a model with hardware specs sufficient for how you intend to use it.

Most "deals" are for low end hardware or old stock. Keep an eye out for higher percentages off at a vendor like Dell, and then simply build your own. Christmas two years ago I got a Dell for the wife using a 25% off and free shipping special.

There are USB3 Flash Drives with 200-300MBps Read/Write real world speeds. Which would be faster than my fastest HDDs, which also has to deal with fragmentation slow down. It would be best to upgrade your RAM, which usually has speeds of 3,000 to more than 5,000MBps but if you can't then this could be a ok stop gap. Better than using the HDD for extra virtual RAM.

Or you could just get/build a desktop with a spec suitable for what you want to do.
