That article implies you can do special things to increase performance. Maybe, don't care to check. What it mentions that are widely applicable are block sizes and trimming which are built into modern filesystems/drivers. I had performance decrease over time but am not sure the reason he gives

Re: [gentoo-user] Preserving the initial partionin/formatting of an usbstick

The USB drive should be exposed via the mass storage interface as just plain storage. You don't need to do anything special. Older drives needed the user to be aware of the physical layout. Now the firmware mostly takes care of it.

Hi Ia, thanks for your reply ! :) The usbstick I want to make an initial backup is 64GB of size. That means, I will backup mostly zeroes. Where are the partioning/format defining on the device? If there are only stored the beginning of the device: How much do I need to copy? or: If there are

Re: [gentoo-user] Preserving the initial partionin/formatting of an usbstick

If you're gonna dd a drive you either go the same space or larger. To be sure you get everything you can just dd if=/dev/oldstick of=/dev/newstick Replacing old/newstick with the correct device. You can even keep a backup image with dd if=/dev/oldstick of=/home/user/whateveryounamedit.img

[gentoo-user] Preserving the initial partionin/formatting of an usbstick

Hi, since companies know their usbstick internals best, they format their drives in a way, that the performance is best. That's why I want to make a complete image "backup" of my new usbstick first before using it in case of needing to reset the whole thing. The stick is a 64GB vfat formatted
