Solved: fastest usb stick ?
Hi,
I have a Lenovo Thinkpad x200, 4gb ram, win 7 pro, ubuntu 12.04 64bit on a usb and an sd card.
Have noticed ubuntu runs slowly and freezes with a darkened screen. Originally thought it to be too many rss feeds and removed most of them but, the slow running still remains. This could simply be, the x200 is designed to run best with windows.
would a faster usb stick or sd card improve the running of ubuntu and what brand is a good recommendation ?
I've seen a scandisk extreme pro sd card with a speed of 95MB/s, would this be good to run ubuntu on my x200 ? I use LiLi USB software for ubuntu.

When does it freeze exactly? Remember that nothing is run from storage. All programs run from RAM long after they have been loaded from their storage location. It may not be the stick that is the problem.

It seems to freeze mostly when it's online. have tried turning 'javascript' and 'load images automatically' off and this helps a little but the freezing still happens. Dead slow compared to windows even though ubuntu 64bit is accessing all 4GB of the RAM.

The way you "installed" Ubuntu onto that USB wasn't an actual "installation." All you did was basically create a LiveCD and put it on a USB stick.

I think you'd get better performance with an actual "installation".

The way to do that would be to create a Live CD/DVD, boot it up and choose "Install Ubuntu". Then install it directly onto your USB stick. For convenience, install the grub boot loader onto the USB stick instead of the main hard drive.

Now have a 64GB sandisk USB. Tried a full installation of Ubuntu 12.04 64bit, boot the live CD, choose install, when offered I choose 'something else' from installation type then get a choice table/menu, I make a partition of 10GB FAT32

/dev/sdb
/dev/sdb1 fat32 9999MB unknown
free space 54015MB

when trying to move on from that point get message;

no root file system is defined
please correct from partitioning menu

I'm stuck here

Did you buy the drive from a legitimate source? It's about $40. If you bought it on eBay and/or paid significantly less, it's a fake.

Read on the Ubuntu site earlier about installing to USB and it mentions about needing to be FAT16 partition. Eh ? I was told to format FAT32 for the live versions. This new USB arrived FAT32.
my brain, my brain, it does not compute.

If you're trying to do an actual "installation" rather than a LiveUSB, then you need to format to EXT4.

The all new Ubuntu stick is in operation. EXT4 worked. First thing I did was to try it out online and again it's still sluggish and freezes ups with a darkened screen.
But it's early days. The install worked so thanks again.
