Maxtor's Central Axis (US$319.99) offers a new way to add a centralized, always-available terabyte of storage to your local network, whether you install it at home to share media files or set it up at work to share proposals among your colleagues. You can even stream your media to UPnP AV-compatible (Universal Plug and Play Audio/Visual) networked entertainment systems without using a computer. Best of all, by setting up an account with Seagate Global Access, you can store and retrieve files from the Central Axis device over the Internet.

To be truly effective, a backup application must let you easily choose what you back up, simplify recovery and not slow down your work. So I was looking forward to evaluating DataSentinel, a combination of hardware, software and storage service.

There's no such thing as too much protection for your valuable files. Although external hard drives can provide backup copies of files on your hard drive, what if you use external drives for primary storage? Sure, you can use yet another external backup drive, but a better solution might be a RAID array with two drives. Western Digital offers such a system with its new My Book Mirror Edition ($AUD699).

These days, you never know what connections you'll need to add to an older system -- or, for that matter, to a new one. (How many ports does that Macbook Air have again?)

If you want to squeeze the greatest amount of data onto your hard drive, compression is the way to go -- and the ZIP format has long been a trusted method that nearly any Windows user can invoke. SmithMicro's StuffIt Deluxe 12 is a file-compression utility on steroids: it can archive and compress files of all types (to the Stuffit format and even to ZIP itself). The real question is: How well does it hold up against a well-known and popular application such as WinZip?

Next to a laptop's screen, the hard drive is one of the most sensitive parts you need to be concerned with. Samsung's new SSD (solid state disk) replaces a hard disk drive with flash memory (NAND flash, to be precise). The result: a more reliable, quieter, cooler, and faster way to operate your laptop.

Sony Electronics' Vaio TZ191N notebook proves that good things do come in small packages. Inside the black carbon-fiber case is an Intel Centrino Duo processor (a 945GMS chip running at 1.2 GHz) with a bus speed of 533 MHz, 2GB DDR2 SDRAM and a double-layer DVD writer. The 11.1-in. WXGA active-matrix TFT color LCD screen (1,366 by 768 resolution) is amazingly sharp and drew oohs and ahhs from colleagues. In terms of size and weight, it's a road warrior's dream: It measures 10.9 in. wide by 7.8 in. deep by 1 in. high and weighs in at a mere 2 lb. 10 oz. (with battery) or 3 lb. 6 oz. (if you throw the power cord into your travel bag).
