speed difference USB 2.0 vs 3.0?

[mikeschn]

For those of you guys running Puppy on a USB stick, is there a big difference when booting/saving between a USB2.0 and USB3.0?

and if you happen to know, how does the speed of the CD compare to the USB?

Thanks

Don't know how much faster USB3 is than USB2, but I boot using USB2 from a 16Gig stick and it is significantly faster than CD.

Cool! Thanks guys. So I guess there's no need to run out and buy a machine that has USB3.0

CD is pretty slow by comparison these days, but DVD is much faster.
And BlueRay I don`t have a drive yet. They`re even faster I`m sure.

The USB3 spec. is much faster than USB2, but the device is the speed limit.
I`ve had USB2 flash drives that were not much faster than USB1.1

It`s like the SATA interface, they keep making it faster and faster.
But 3.5 inch H.D.s are still the same speed ( approximately 60 MBs ).
S.S.D.s are able to make use of SATA`s blazing interface speeds.

Slacko, Lucid, and Saluki are 130 MB or less, savefile 512 MB for me, which means my computer needs to load ~650 MB into RAM, as I do frugal installs. USB 2.0 is up to 480 mb/sec and USB 3.0 is up to 5.0 GB/sec. Does that mean that USB 2.0 will load 650 1.5 secs into RAM, and USB 3.0 will load in ~ 0.13 sec into RAM, assuming maximum speeds? For a small distro like Puppy, is going to USB 3.0 really going to make a significant difference? Has someone installed the same Puppy on a USB 2.0 stick and USB 3.0 stick and booted from the same computer (obviously plugging the 2.0 stick into a 2.0 port and the 3.0 into a 3.0 port)? What has been your experience?

I just bought a couple USB 3.0 sticks, and I might buy a USB 3.0 PCI card to upgrade my system.

I had a couple computers that I sold recently that had Puppy frugally installed (slacko and lucid), and it loaded much more quickly than with a CD. The savefile was saved on the HD for both the HD and CD boot. I also booted from USB 2.0, and it was significantly faster than CD. However, saving the savefile to USB seemed fairly slow on my system.

The save file is the biggest file in Puppy, so slow to save of course.

I`m trying to setup a transparently compressed Save file for Puppy.
It`d run and save/restore faster, and take less ram and USB space.

e2compr is light and simple and probably a good choice.

Btrfs is the new Ext4 replacement, and does on-the-fly compression.
It will be the next main stream Linux FS very soon, a good choice too.

Both require compiling a new kernel and some of the FS tools.
