I use SanDisk Ultra's 16GB's on my bbw & bbb's on my gcc testing farm. Those microSD's have been running fine for almost a year now, under 100% load for 24/7 bulding/testing gcc stable branches. (lots of file deletions/creations). Previously to that i had been running SanDisk Ultra's 8GB variants, but starting with gcc-4_8-branch i began to run out of build space. http://rcn-ee.homeip.net:81/dl/gcc/archive/20140610-11:24-gitb28747e-gcc-4_9-branch-am335x-boneblack-512mb-1/ Regards, -- Robert Nelson http://www.rcn-ee.com/ -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
