Why Don't Laptops Have USB 3.0?

Cnet's Brooke Crothers says he's been asking himself a lot lately why his laptop doesn't have USB 3.0, observing that there should be a USB 3.0 port on his 2010 MacBook Air, but there isn't - and it's not necessarily Apple's fault, since none of his Windows laptops have USB 3.0 ports either. Nor, for that matter do, the the laptops purchased recently by his business acquaintances.

So what's the holdup? Crothers says he finds the various explanations and excuses made by industry spokespersons lame, noting that they don't change the fact that devices he uses demand a faster USB interface - now (or in fact yesterday), and that Intel/Apple's Thunderbolt, as promising as it sounds, does nothing for consumers today.

In the end, Crothers points the finger at Intel, since its chipsets power the bulk of the worlds PCs, and those chipsets don't yet support USB 3.0.

Editor's note: I can identify, having been on a Late 2008 Unibody MacBook for the last two-plus years that has no high-speed I/O interface at all. Sorry, but USB 2.0 is a poor excuse for one. cm

O'Grady's Wish List for the 2011 MacBook Air

ZDNet's Jason D. O'Grady says he uses his 11" MacBook Air almost as much as his workhorse 15" MacBook Pro, and he's been waiting for a next-generation model to replace it, widely rumored to be coming in June with Intel Sandy Bridge Core "i" processor silicon and Thunderbolt I/O support. In addition to the Core "i" CPU and Thunderbolt upgrades, which in my estimation are a given, the two other items on his MacBook Air wish list are:

  1. A backlit keyboard.
  2. Upgradable, socketed RAM

New iMac or 17" MacBook Pro: Which Is Right for You?

Laptop Mag's Kenneth Butler says that with Apple having added its for now exclusive Thunderbolt I/O ports to its latest iMac models, many users will be trying to choose between buying the stationary performance of an all-in-one desktop or the limited portability of a 17" MacBook Pro that also supports Thunderbolt.

He's posted spec comparisons to help you figure that out.

Apple Working on Fix for SATA 6 Gbps Bug in 2011 MacBook Pro

Hardmac's Lionel report that there's good news for folks who've been waiting for Apple to fix the SATA 6 Gbps bug on the 2011 MacBook Pro. Hardmac has been tenaciously covering this story, and Lionel links to the editor of the Mac Performance Guide announcing that after several discussions with Apple, the company asked him to send back his 17" MacBook Pro with his SATA 6 Gbps SSD inside to be tested by Apple engineers. He received a new MacBook Pro, and Apple reimbursed him for the cost of the SSD. He reports that the replacement runs without any problem with a SATA 6 Gbps SSD.

How to Replace Your MacBook Air SSD with OWC's Aura Pro Express

Ars Technica's Chris Foresman has posted an illustrated tutorial article on replacing the original, Toshiba-sourced, SSD flash memory drive in Apple's Late 2010 MacBook Air models with Other World Computing's Mercury Aura Pro Express SSD, which uses faster SandForce controllers.

Finding a Protective Shell for a MacBook Pro

Blogger and sometime PC switcher David Allison says:

"When I packaged up my old MacBook Pro for my daughter, I did a quick wipe down of the machine and found that though it was three years old it had very little visible wear and tear. The keyboard and palm rest areas were in perfect shape, and there were no dents in the aluminum case. Though the white power supply and cords were a bit dirty, a quick wipe down with a damp cloth had them looking like new.

"About the only thing that made the machine look used was the outside of the case. As I had slipped it into my bag or carried it in my hand, objects like my watch band had rubbed against it and put a series of small scratches all over the outer shell. They were purely cosmetic but annoying nonetheless.

"I'm determined to treat this new MacBook Pro with a little more care, and as a result started searching around for a protective shell case for it...."

SSD Wear Leveling Demystified

Storage Switzerland analyst George Crump writing for InformationWeek's says:

"Solid state storage brings high performance to the enterprise through memory-based, zero-latent storage. It also brings with it new terms that may be confusing. One of those is wear leveling. Most solid state storage vendors have controllers on the memory that handle wear leveling for you, but the reason to understand wear leveling is so that you understand how it impacts the performance of the storage systems you are purchasing."

Editor's note: This is the clearest and most concise explanation of this issue I've seen yet. cm
