ffi Posted September 17, 2008 Share Posted September 17, 2008 (edited) I installed cooker on a usb flashdisk (ext2) and everytime I do some intensive file operations like urpmi, processes in ksysguard say disk sleep. I see a package being installed, which goes quite fast and then the next one takes ages to continue and so on, all the while when waiting seeing usb-storage and urpmi in disk sleep state I bought the flash disk asking for the fasted (and most expensive) and it said it was readyboost ready. in ps aux the states are listed as D+ and D< Edited September 17, 2008 by ffi Link to comment Share on other sites More sharing options...

scarecrow Posted September 18, 2008 Share Posted September 18, 2008 Running a regular linux disto out of some USB-key is a safe way to render the key useless sooner rather than later... simply too many I/O requests. Link to comment Share on other sites More sharing options...
