Magic Buses

Our future gadgets will do more wirelessly than ever before. But they'll be able to do even more with wires.

It's USB's World, We Just Live Here

Once an upstart newcomer, USB has become an elder statesman in the electronics world with a presence in almost every device on Earth. But USB’s data-transfer speeds, last boosted by USB 2.0’s introduction in 2001, haven’t aged gracefully. Thankfully, USB 3.0 is here to breathe new life into an old favorite.

USB 3.0 cables definitely lose the beauty contest to Light Peak (below).

At first glance, USB 3.0 (a.k.a. SuperSpeed USB) doesn’t seem like a radical departure from its predecessor, and that’s a good thing. It’s backward-compatible with USB 2.0 and even uses the same rectangular port we all know and love, so your old devices will work just fine with the new standard. So don’t worry, you won’t have to buy a new USB beverage warmer for your cubicle.

But USB 3.0 brings two new tricks to the table. The first is speed--its transfer rates reach up to 5Gbps, or 10 times USB 2.0’s performance. The second is improved power management, which means reduced power consumption and more juice for devices that need it. USB 3.0 gear is already on the market, so it’s only a matter of time before Cupertino rolls out the first Macs with the SuperSpeed standard. We hope they come soon--we’ve got HD video to import!

One Wire to Rule Them All

Fiber optic cables, long used by telephone companies to connect landline phone calls, have numerous advantages over traditional copper wires. So why haven’t they made it to the desktop yet? Intel hopes to put that question to rest with a new technology called Light Peak.

Light Peak is Intel’s answer to…well, just about every cable in use today. From HDMI to USB, if it carries data, Light Peak can replace it. That’s because Light Peak’s bandwidth starts at 10Gbps, and its theoretical ceiling is a whopping 100Gbps. And since Light Peak’s flexible fiber optic cables transmit light, not electricity, they can carry data up to 100 meters without a hitch. That’s plenty more meters than we need, but some room to grow can’t hurt, right?

Light Peak brings fiber optic speed to computing. And pretty colors, too.

However, despite a planned 2011 rollout, don’t expect to sync your 5G iPhone with Light Peak. Intel is still working out ways to combine power with Light Peak to charge devices while beaming data at warp speed. One thing’s for sure, though--when Light Peak finally strikes, it’ll be fast.

Reading, Writing, Revolutionary

Say goodbye to your old drives. Say hello to a new world of speedy storage.

It's RAM! It's a Hard Drive! It's Both!

There’s nothing New Age about “universal memory,” but it could usher in a new age of computers and electronic devices. Universal memory is any next-gen storage that combines the speed and affordability of today’s DRAM with the permanence and capacity of flash memory. Two technologies are fighting to rewrite the rules, and the winner may be coming to the Mac sooner than you think.

Phase-change memory (PCM) gets our vote, if only for its cool name, which is derived from the use of chalcogenide glass that changes from a crystalline to an amorphous state with heat. It’s the same material used to make rewritable optical discs, but in PCM, the two states represent different electrical charges, or a zero and a one. PCM represents a major leap in durability over flash memory, and can be written to up to 100 million times versus flash’s upper limit of just 100,000 read-write cycles. Samsung has already begun producing 512MB PCM modules for use in mobile phones, but 1GB modules are still on the way. Looks like phase-change doesn’t happen overnight.

The race for better memory is run on a tiny field, though, and IBM’s racetrack memory may have the inside track. It uses something called spintronics--don’t you want to hear Steve say that at a keynote?--to manipulate electrons into moving magnetic bits down nanoscopic, U-shaped “racetracks” to read and write data at blazing speed. Yet racetrack memory’s biggest asset may be its scalability, theoretically allowing HDD-size capacity to be squeezed into a much smaller area than competing technologies allow. But until racetrack memory is ready to leave IBM’s labs, this dark-horse contender will be one to watch, not buy.

Kind of Blu

Steve famously quipped that bringing Blu-Ray to the Mac was “a bag of hurt,” but Sony’s multimedia power-platter is still rolling along after years of Cupertino’s cold shoulder. Movie lovers--and anyone who wants to share giant files--can take comfort that when Blu-Ray finally arrives on Macs, it’ll be better than ever. Having long shed its 25GB limit, Blu now boasts capacities of up to 400GB, and 1TB discs are coming in just a few years. The promise of this year’s 3D Blu-Ray players is just one more feature that will keep Mac fans gazing longingly--sigh--at Big Blu’s bag of tricks.
