I will do the test. When I saw the time remaining I canceled the task.

1h 8min

Started : 17:44
Finished: 18:52

The question is: why CCleaner spends 1 hour and Eraser spends 6 minutes? Eraser not is a good software?

Not neccessarily bad software. It may be how each reads the USB drive and the"speed" of the USB. Personally I would put more trust in software that takes the longer time giving the confidence it has done its job.
But since you've run both the drive is certainly wiped clean.
I don't know why CCleaner takes so much longer, I used it to wipe a 8GB drive, 7 passes, in under 20 minutes.

The problem was my USB drive. It is very slow and very old. I used other USB drive 2.0 with 4GB and CC's Disk Wiper can cleaned it in few minutes.

Thank you for your help?

Wildly Overstated Performance?

The only thing that I can think of is that USB Flash stick manufacturers wildly overstate the performance of their devices.

Copying files to my USB stick takes stupid amounts of time.
I'd swear that my USB HDDs are actually faster.

I have an old PNY 8GB which has very slow write speeds. I have a new AData S102 in 8 and 32GB which flies on write. They are USB 3.0, in the USB 3.0 port they are very fast, copying I have seen around 180-220 MBs.
The Patriot XT XPorter is almost as fast with its USB 2.0 interface.

My old USB is a MP3 Player (with many years of use). I guess it is an USB 1.1. Very slow to write. My new USB is a Kingston Black Jack 4GB USB 2.0, very fast for write and read, with one week of use.
