On test: OCZ Secure Digital Trifecta 66X (2GB)
Despite the best attempts of many an interested party, Secure Digital memory cards have become more or less the de facto memory card format. CompactFlash remains popular among photographers, and Sony continues to soldier on with its mad variety of formats but in general Secure Digital has won out and the great majority of consumer electronics devices support it.
With devices becoming ever smaller, new SD memory standards have been created including miniSD and microSD which, as the names suggest, are smaller versions of SD cards, which are compatible with SD card interfaces via adapters.

"PNY 1GB Memory Stick Pro Duo"
Issue: 7/2007
On test: PNY Memory Stick Pro Duo (1GB)
Memory Stick Pro Duo memory cards are used in some Sony digital cameras, Sony music mobile phones such as the Walkman W810i, and the Sony PSP. PNY's 1GB stick has enough room for around 320 6-megapixel photos, 250 MP3 music files or roughly two hours and 45 minutes of PSP-compatible MP4 video. It comes with an adaptor to use in older devices with Memory Stick slots.
"Kingston 1G microSD card"
Issue: 60/2007
On test: Kingston microSD Card (1GB with adaptor)
When you're buying a new device it's easy to overlook the memory card format it uses as something worthy of consideration. Yet if you've got a handful of SD cards that won't fit into the microSD slot in your new smartphone then it will have an impact on the total cost of ownership of that device. And there's also the convenience factor of being able to swap cards between different devices at will.
With these issues in mind, the main selling point of Kingston's new range of microSD cards is not the 1GB of storage, welcome though it is at a keen price, but the two adaptors that come with it.
"SanDisk Ultra II SD Plus USB card"
Published on: 3/2007
On test: SanDisk Ultra II SD Plus (2GB)
We all love taking pictures, but unless you have one of those new wireless cameras from Nikon or Kodak then getting them to your computer can be a bit of a bore.
SanDisk believes it has solved this problem with its SD PLUS range available in 1GB and 2GB sizes, why have we chosen to review a memory card? Because this one has a twist to it.
Memory Cards
The pictures taken on a digital camera can be saved to a number of places. There is currently no standard memory card although two are becoming the most popular used in consumer devices. These are the xD memory card and the SD card. In professional devices the compact flash card is the most used as it offers much higher capacities. An SD (secure digital) card is favoured by nearly all camera manufacturers except Olympus and Fuji and is also used in many PDAs and mobile phones. SD cards offer a speed normally around 10MB/s but there are cards with double this speed. These will be marked 133x or high speed and are required by some cameras when making videos or taking concurrent photos at high speeds. SD cards are available in sizes up to 2GB, a 512MB card will normally have enough space for 150 photos at 5 mega pixels. xD cards are a little slower than SD but are smaller and use less power. They are available in the same sizes as SD cards. With the use of a card reader/writer, memory cards can be used as external storage.
