Online backup company Backblaze has produced another report on hard drive reliability, this time looking at specific vendors and models. Overall, drives from Hitachi (now owned by Western Digital) came out on top, with a 96.9 percent survival rate after 36 months. Second was Western Digital, whose drives had a quick initial die-off, but then stabilized with an overall 94.8 percent survival rate. In a distant third place was Seagate with a 73.5 percent survival rate. In spite of that, Backblaze is now buying mostly 4 TB Seagate drives due to their low cost and steady performance; the company also likes the Western Digital 3 TB Red drives. follow link
Single Time Machine Backups
Tired of Time Machine running all the time? You can turn it off in the Time Machine preference pane, but still initiate a single backup by choosing Back Up Now from Time Machine's menu bar icon. Of course, your backup is much less likely to be up to date, but Time Machine won't be taking any resources while you're trying to work.
