Flash Memory Cards

What is Smart Media?

Smart Media is the oldest of the portable media formats still in (limited) use today, dating back to 1995. Originally envisaged as part portable media device, part replacement floppy -- hence its initial weighty nomenclature of Solid State Floppy Disk Card (SSFDC), it is notable for the now restrictive size limitations on individual cards -- which top out at 128MB -- and the fact that at 0.76mm thick, it's the thinnest of the portable memory card formats. Despite no longer being manufactured, Smart Media continues to enjoy a healthy user-base thanks to the proliferation of multi-card readers in PCs and desktops.

What is XD-Picture card?

FujiFilm XD Card

XD-Picture card is a standard card jointly developed by Olympus and Fujifilm, so it should come as little surprise that Olympus and Fujifilm digital cameras are the primary places you'll find the tiny (20x25x1.78mm) card in use. XD (stands for eXtreme Digital) cards come in sizes from 16MB up to 2GB, with read/write speeds that vary from 5MBps/1.3MBps up to 3MBps/5MBps. However, the highest capacity cards (over 512MB) use a different internal architecture that gives them extra capacity but this comes at the expense of lower read/write speeds and some compatibility issues with certain older cameras.

Flash Drives with everything

Storage availability within memory cards has risen over the years, but there's also a class of products that do more than offer memory card storage. One of the most popular additional features to add to a flash memory card is wireless network connectivity. Memory cards are available from a variety of manufacturers across different memory card formats that support Wi-Fi access, although you'll need a device (usually a PDA or smartphone) that will actively support Wi-Fi connections. It's not purely limited to the PDA world, however, as Sony used to offer a Wi-Fi Memory Stick for its now locally discontinued Aibo Robot Dog.

The one thing to bear in mind with any feature-enhanced memory card is that all the extra functionality comes at a price, usually in the amount of power that the device needs to draw.

First impression on unpacking the Q702 test unit was the solid feel and clean, minimalist styling.

Anthony Grifoni


For work use, Microsoft Word and Excel programs pre-installed on the device are adequate for preparing short documents.

Steph Mundell


The Fujitsu LifeBook UH574 allowed for great mobility without being obnoxiously heavy or clunky. Its twelve hours of battery life did not disappoint.

Andrew Mitsi


The screen was particularly good. It is bright and visible from most angles, however heat is an issue, particularly around the Windows button on the front, and on the back where the battery housing is located.

Simon Harriott


My first impression after unboxing the Q702 is that it is a nice looking unit. Styling is somewhat minimalist but very effective. The tablet part, once detached, has a nice weight, and no buttons or switches are located in awkward or intrusive positions.
