This came up on slashdot a while back. I have not tested myself, but apparently the newer generation of SD have pretty good life, 2 million or so writes per block and built-in wear leveling so that's spread evenly. That's what makes it worth shipping flash-based hard drives in the MacBook Air and similar. For example, this site tried to come up with a worst case for a 64G disk: "2 million (write endurance) x 64G (capacity) divided by 80M bytes / sec gives the endurance limited life in seconds. The end result is 51 years!" http://www.storagesearch.com/ssdmyths-endurance.html So it's not as bad as you might fear, but performance is still an issue. -- fedora-test-list mailing list fedora-test-list@xxxxxxxxxx To unsubscribe: https://www.redhat.com/mailman/listinfo/fedora-test-list
