Cloud backup service Backblaze has conducted another study of hard drive reliability, this time pitting consumer-grade hard drives against the more expensive enterprise-level disks. Over the span of three years, 4.2 percent of the consumer drives failed, while the enterprise drives suffered a 4.6 percent failure rate. The caveats are that Backblaze tested 14,719 consumer-grade drives against 368 enterprise drives, and the two sets were used for different purposes. While more data is needed to compare longer-term reliability, Backblaze noted that longer warranties are the one clear advantage of enterprise drives. follow link
Avoid Long Hierarchical Menus
If you right-click (or Control-click) on some item, such as a file in the Finder, and one of the sub-menus has many options (Open With is a frequent culprit), it may take several seconds to open, even on a fast machine, which is annoying if you did not actually want that sub-menu.
The trick is to not pull the cursor through the menu, but in a curve around it, so the cursor does not touch any menu items until lower on the list where you wanted to go.
