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
Viewing Wi-Fi Details in Snow Leopard
In Snow Leopard, hold down the Option key before clicking the AirPort menu. Doing so reveals additional technical details including which standards, speeds, and frequencies you're using to connect, as well as what's in use by other networks. With the Option key held down and with a network already joined, the AirPort menu reveals seven pieces of information: the PHY Mode, the MAC (Media Access Control) address, the channel and band in use, the security method that's in use, the RSSI (Received Signal Strength Indication) measurement, the transmit rate, and the MCS Index. In Leopard, some, but not all, of these details are revealed by Option-clicking the AirPort menu.
