Which is faster, installing from usb or dvd?

Recommended Posts


With a flash drive you don't have to wait for the disk to spin up often, and a USB memory stick makes no noise too!

Indeed - USB 2.0 installs are quite a bit faster than DVD-based installations. I wouldn't necessarily suggest it on a machine with USB 1.1, but 2.0 seems to be plenty fast enough to best DVD transfers.

it will be interesting to see a USB 3.0 install ;) i'll get to try it out with my new motherboard!

Please also note that USB 2.0 generally is NOT the bottleneck in the transfer speed, different sticks/controllers may make MUCH difference.

See this (oldish now) comparison:

http://www.testfreaks.com/blog/review/usb-...d-and-compared/

this should be the most meaningful graph (though of course actual read rates may change greatly depending on size of files and other factors):

but the difference between "good" sticks at around 30 MB/s and "bad" ones at around 10 MB/s is a BIG difference!

According to FAQ #4 here:

http://www.everythingusb.com/usb2/faq.htm

the BUS axtually tops at around 40 MB/s.

As well filesystem used DOES make a difference:

I've also noticed that the file sizes make a huge difference, and there is a large discrepency between reading and writing (not applicable when installing an OS) to a USB flash drive.

My Corsair Flash Voyager 64 GB will read at over 24 Mbit/s via USB 2.0, yet I can only write to it at a measly 3-5 Mbit/s.

With pricing around $150 for 64GB SSD, eSATA is my choice, that should make the destination drive a bottleneck.

Doesn't get much faster than that, unless someone figures a way to mount the entire DVD in RAM. Wasn't there a 512MB limit on the 2K3 RAM-ISO driver, has this been over-come and I just don't know about it ?

Yep, smaller files mean slower speed, see this as a quick reference:

If you are "runnning" on flash device, this may (or may completely fail to :unsure:) help:

Yes there was:

And yes it has. :) You are now outdated. ;)

But of course you need lots of RAM and the time to transfer the data to RAM is anyway needed.
