FlashUSB read/write cycles limit.


I have a laptop with a dead HD, i am currently using Mint17.1 Cinnamon 32 Bits LiveCD. I have a 3.6GB USB and a 7.3GB, i saw somewhere on the internet that flash USB's have a read/write limit, like 5ktimes or something like this. Is it secure to my USB that i use it like a HD? I want to install xubuntu 15 on it, install drivers and use, but i am worried about the read/write cycles, will my pendrive last less time if i do it because of the read/write usb flash limit?. I use the computer every day for like 9 hours.

Sorry for my english.

Thank You.

Performance will be slow - but you can do it.

System I/O is mainly read only, so this won't cause your USB to die.
Depends how many disk writes you do to /home, whether you get any problems.
Having a decent amount of main memory will reduce the amount written out.
Don't use a swap partition.
Do use a Linux file system such as ext4.

Since small USB's are cheap, you can use the live CD to duplicate them on a (say) monthly basis.
This would give you a very basic kind of backup.

I've seen
Quote:
USB flash drives can withstand between 10,000 to 100,000 write/erase cycles, depending on the memory technology used.

You could try the F2FS filesystem as it is designed for this use-case. However, the Mint installer probably doesn't support it (debootstrap & pacstrap FTW!)...
https://en.wikipedia.org/wiki/F2FS

I have a USB3 stick that I have been using to hold various distributions for the last 18 months and it's still going strong.

Games will depend on the video card.
Try a few of the free Xubuntu games in the repositories to get an idea if games will work for you.

I know...What i mean is if i can run a specific "X" game with 100fps on a linux OS installed on HD, how much fps do you think i can get with Linux installed on a 2.0 8GB USB? Can i play a game on that case?
Sry for the english.
Ty

A "small" game that can be loaded into main memory will run at the same speed as one loaded from HD.
A large game that needs access to the USB will suffer, compared to one that that is loaded from HD.

Unless you have a very expensive video card, you will never reach 100fps, regardless of your other hardware.
Note:-
HD's are easy to replace in (plug & go) desktops and are doable in laptops.

The 100fps was just an example, and my laptop is "kind of old", so i think buying a HD for it would be waste of money

I just install linux to faster models of usb flash drives and run them. I never fool with any special tricks or edits. By the time you wear out the flash, it's time for a new drive.

You can easily get a mechanical drive in an enclosure for usb if you want or buy a portable drive. I use them a lot too.


I have some very very old flash drives that were one of the first ever running linux and they still work. Not much use for a 128Mb flash however. It still has a linux distro on it.

What does an 8G drive cost anymore? $4??


You make backup's to protect data.
