The next-generation SDXC (eXtended Capacity) memory card specification, pending release in Q1 2009, dramatically improves consumers’ digital lifestyles by increasing storage capacity from 32 GB up to 2 TB and increasing SD interface read/write speeds up to 104 MB per second in 2009 with a road map to 300 MB per second. SDXC will provide more portable storage and speed, which are often required to support new features in consumer electronic devices and mobile phones.
The SD Association

For those still trying to adjust to the suddenly outdated Secure Digital High Capacity (SDHC) cards, this will be something of a shock.

What happened to SDHC?

For those that are worried about their new SDHC cards and what it will mean to them, well they shouldn’t be too concerned. As far we know, there are no SDXC compatible devices on the market at the moment, so SDHC is still the best format to have. Presumably the devices will also be backwards compatible with SDHC and standard SD cards too, so no need to throw away your old cards just yet.

For those who don’t know, SDHC was the next generation of SD cards released just a little under three years ago, taking the maximum capacity all the way from 2GB (the standard SD cards maximum capacity) up to 32GB. That wasn’t the whole picture though, there were many problems with the larger format cards, even 2GB SD cards were not always assured to work in SD cards readers, 4GB SDHC cards made the situation even more confusing, and for some it made purchasing a new SD card something of a minefield.

Many devices, such as the Nintendo Wii, did not support the new format SDHC cards, leaving their owners stuck on with a maximum 2GB card. We’ve always advised those looking for a new SD card to check their device for an SDHC compatible logo, otherwise to stick to the 2GB SD cards for best compatibility.

Most new devices do now support SDHC cards, however with the new SDXC format due to appear in March this year, it is likely that the confusion will begin again.

Terrabytes

If you are unsure, anything larger than 32GB is not SDHC, as that is the capacity limit for those cards. 32 Gigabytes may have seemed ample when SDHC was conceived, but in today’s High Definition world, it isn’t really enough. Even the largest capacity SDHC cards could only fit a little over 4 hours of HD recording on the card (a standard 2GB SD card, less than 30mins).

When SD cards were first released we talked in capacities of megabytes, with the emergence of SDHC this soon changed to gigabytes (1024 megabytes) and now with Secure Digital eXtended capacity we have moved up again into terrabytes (1024 gigabytes), albeit only two. Amazingly the SDXC cards have a maximum capacity of 2TB (terrabytes), which means up to 480 hours of HD recording!

A 2 TB SDXC memory card can store 100 HD movies, 480 hours of HD recording or 136,000 fine-grade photos. Faster bus speeds will enable professional-level recording in compact consumer camcorders and increase the number of frames shot in a second with SDXC cameras.

An incredible amount of space, although it will probably be some years before we see such cards on the market, and even longer before they are at an affordable price on a par with today’s popular 8GB SDHC cards.

“We’re not thinking about fighting Sony, but about how many people we can get to play games. The thing we’re thinking about most is not portable systems, consoles, and so forth, but that we want to get new people playing games.”

I don’t think even he could have foreseen just how popular it would become and just what a difference the Nintendo Wii would make to the gaming world.

The machine is unbelievably popular, and as he noted, not just in the traditional market. We now see Nintendo Wii’s in the homes of the traditional gamers parents, their grandparents and even in nursing homes. Something that was inconceivable before the Wii came along.

Secure Digital Cards

The Wii isn’t much compared to the other next generation consoles, in fact it barely measures up specification wise to the XBox, let alone the XBox 360. It is also lacking in the storage department, only having 512MB of storage (the Xbox had about 10GB), but it does allow owners to add pictures and files from their own SD cards.

A smart move by Nintendo, the Xbox 360 uses it’s own propriety memory cards, but the SD card has become the de facto standard for flash memory cards in recent years, with most people having several cards from digital cameras, PDAs, mobile phones and now even sat-navs, lying around the home. Not to mention the fact that they can also use the newer miniSD and microSD cards as well with an adaptor. SD cards are a very cheap form of storage, allowing users to more than double the storage capacity of their Wii for less than £3.

Secure Digital High Capacity Cards

Sadly, despite coming to market several months after SDHC, the Nintendo Wii does not support SDHC cards and this has caused some issues for those looking to expand their Nintendo Wii’s storage capacity.

SDHC itself is something of a murky area, many manufacturers and retailers do not do enough to make customers aware of what SDHC is, why it is different from standard SD, or even that it is different.

SDHC is a completely different standard to standard SD and is not backwards compatible. There is more information on SDHC on the Horizon Web Blog – The Mystery Behind SDHC. But in a nutshell, unless your camera, mobile phone, sat-nav or PDA specifically says that it supports SDHC cards, it more than likely does not.

So although those new 4GB, 8GB and even 16GB and 32GB SD cards may seem like an excellent way of perhaps recording more video or taking thousands of photographs, rather than just hundreds, unfortunately for most people, particulary those with devices a year or two old, it just isn’t possible.

If you’re in any doubt as to whether your device is SDHC compatible, feel free to contact us at Horizon Flash Memory, or even comment here with the make and model of your device and we’d be happy to let you know.

Conflicting Advice

Nintendo Wii owners, like most people it seems, have difficulty finding out whether their device is SDHC compatible and then which cards to purchase. A simple search for ‘Nintendo Wii compatible SD cards‘, turns up all sorts of conflicting advice.

Even the Nintendo Wii website itself makes no mention of SDHC cards, simply stating that the Wii is only compatible with SD cards of 2GB or less.

At Horizon Flash Memory, we can give simple clear advice on this issue, SDHC cards are not compatible with the Nintendo Wii, no cards more than 2GB in capacity will work. Needless to say all of our SD cards of 2GB or less are 100% compatible with the Nintendo Wii – and this is guaranteed.

Cheap As Chips

There is an upside however to not being able to use the newer, higher capacity SD cards. As the capacities get higher and higher the prices at the bottom end of the capacity scale get cheaper and cheaper.

If you shop around you can find lower capacity SD cards at unbelievably low prices. Strangely, there are also places that sell 512MB SD cards for between £8-£10 each! So as always it is important to shop around to get the best deals.

And while our 1GB and 2GB SD cards are not quite as cheap as chips, at £2.99 and £4.49 respectively, they are both cheaper than cod and chips, and offer fantastic value.
