FIRST POST!:D :

I want to download ubuntu 11.04 to my brand new 16gig flash drive from windows vista or the ubuntu live cd. I read on https://wiki.ubuntu.com/LiveUsbPendrivePersistent that if i just use the regular installer, I am at risk of wearing out my flash memory more quickly. I dont like the link they posted under method 2. My question is: If what i read is true, what is the best way to put the full ubuntu installation on my flash drive (I expect that it involves partitioning my flash drive)?

Hi, welcome to the fora.

If you are using Windows, I would recommend Unetbootin.

Thanks ill look into that but i also need to know if the os will be to "write-intensive" and wear out the flash drive too quickly. I will not be surprised if this is true but i already got it so i just want to be certain. I should have just gotten the external hard drive, but those are such a pain to carry around;).

Sorry, I don't know of that.

If you have a cheap 1 or 2 GB USB stick you could use that for testing. We would like to hear the results :-)

If you have a 16GB flash, you want to do a full install. Persistence is limited to 4GB, I think, but you could partition and have space to store other data.

You do want to change some settings to reduce writes, just like you would with a SSD. But since it is flash and thru a USB port do not expect it to be fast. I have installed it to my 16GB flash in a 8GB partition and it is functional.

It does not have to be encrypted BIOS based system:
Standard full install with screenshots to flash or SSD:

Use ext2 or ext4 without journal:
tune2fs -O ^has_journal /dev/sda1
No swap or set swapiness
After installing, change the fstab so that everything gets mounted with noatime.
change to noop i/o scheduler

@morgaes, I will be sure to post the results. It would be great to *safely* carry around the best os around in my pocket ;)

@oldfred, thanks for those suggestions; they should help a lot.

Im going to leave this thread open so that I (and anyone else) can post experiences on this topic. So please leave any info you have!
