The new Seagate Cheetah bumps capacity to 600GB, adds a SAS 6Gbps interface, and spins at a familiar 15,000 RPM. It’s still a 3.5″ drive, though, and the world is wondering how long it will be before the transition to 2.5″.
Seagate Cheetah 15k.7: 3.5″ in an increasingly 2.5″ world. Seagate yesterday announced it is shipping a new hard disk, the Cheetah 15k.7, to OEMs and retailers. Aimed at the server segment, the seventh-generation Cheetah drive brings 600GB capacity, 6Gbps SAS and 4Gbps Fibre Channel, and new power management technology to the 3.5″, 15,000 RPM segment.
1TB disks now cost about $75, making disks one of the cheaper parts of a modern desktop or laptop computer. The HDD market is so commodified that products from competing vendors perform and cost roughly the same; quality differentials between brands are largely a thing of the past. There is, however, one segment of the hard disk market where prices and margins are high: SAS server disks with fast rotational speeds and SCSI interfaces. The current drive, the Cheetah 15k.6, tops out at 450GB for a trifling $500. No price has been announced for the 15k.7, but prior generations of Cheetahs have launched at $600.

The biggest drawback of Web-based software, including e-mail programs like Gmail, Yahoo Mail and Microsoft’s Hotmail, is that they don’t work when users are offline — say, while on an airplane or on the road without access to a Wi-Fi connection.
On Tuesday evening, Google made Gmail available for offline use, in what the company calls an “experimental feature.”
Google is not the first of the major Web e-mail providers to provide offline access to its service. Yahoo did it last year, though its approach requires users to download a desktop e-mail software program called Zimbra, which Yahoo acquired in 2007. (Zimbra can also be used for offline access to Gmail and AOL Mail.) Microsoft’s Windows Live Mail offers limited offline access. And Zoho, a smaller provider of Web e-mail, has provided offline access since October.
Most Web e-mail services have long allowed users to download their messages to desktop clients like Microsoft Outlook via POP or IMAP technology. Read the rest of this entry »

A group of 38 computer scientists, law professors and security experts is urging Google to do to more to protect Gmail, Google Calendar and Google Docs from snooping.
Specifically, the group is asking Google to use a standard encryption technology, known as HTTPS, that is commonly used by online banks and other Web sites to protect users’ data while in transit. Google already offers HTTPS, which stands for Hypertext Transfer Protocol Secure, as an option in Gmail and other services, but it is disabled by default and few users know about it or bother to turn it on, the group said.
“Google customers who compose e-mail, documents, spreadsheets, presentations and calendar plans from a public connection (such as open wireless networks in coffee shops, libraries, and schools) face a very real risk of data theft and snooping, even by unsophisticated attackers,” the group wrote in an open letter to Eric Schmidt, Google’s chief executive. “Tools to steal information are widely available on the Internet.” Read the rest of this entry »
