When I wrote a series of How-To guides showing how easy it was to swap old Mac hard disks for new solid state drives (SSDs), I focused on raw upgrades — slow mechanical drives for fast chip-based ones. The reason was simple: put an SSD in your Mac instead of the old hard disk, and you’ll be blown away by the speed increases. But as several readers have noted, there is another way to add an SSD to your Mac: you can keep your old hard drive, and instead replace the Mac’s CD/DVD optical drive, also known as a SuperDrive.

Swapping a SuperDrive for an SSD has a mix of pros and cons. It’s typically a little easier and less expensive to replace the SuperDrive than a stock hard drive, and you’ll always wind up with more internal storage than you started with. But you also lose CD/DVD reading and writing abilities — things fewer people care about these days — and you’ll need to set up your Mac to properly take advantage of the SSD. Read on for the details…

As Apple’s iPhone 5S event approaches, some new details about the new device’s internals are emerging. Clayton Morris has claimed on Twitter that the iPhone 5S’s A7 processor is “running at about 31% faster” than the iPhone 5’s A6 chip. The iPhone 5’s A6 chip is dual-core, and it seems like the iPhone 5S will also remain dual-core.

However, there could be a major differentiator: 64-bit. We’ve independently heard claims that some of the iPhone 5S internal prototypes include 64-bit processors.

It’s unclear if 64-bit will make the cut, but it’s been in testing. We’re told that the 64-bit processing will assist the A7 chip in making animations, transparencies, and other iOS 7 graphical effects appear much more smoothly than on existing iOS Devices…

Update: a person in the know has pointed out a few problems with Brown’s post:

  1. It was taken down and is currently down.
  2. If you look at one of the lines of Apple’s code that he uses to allege throttling, it doesn’t even have anything to do with throttling internet speed. It’s just the term, used to talk about how often a phone should ping the network when it doesn’t encounter a signal, or something like that.
  3. AnandTech posted a lengthy article explaining why it just isn’t true.

Joseph Brown, the developer behind the hacked carrier updates floating around for AT&T, Sprint, Verizon, and T-Mobile, just posted a lengthy blog post detailing how he claims “Apple limits devices to even out” the networks of its carrier partners. Specifically, Brown says that Apple is limiting the iPhone 5 to Category 10 (14.4Mbps) HSDPA despite the device’s support for category 24 (42.2Mbps) DC-HSDPA+ and the AT&T network supporting up to Category 14 (21.1Mbps) HSDPA+:

Here we can see what is quite obvious to, really, anyone at this point from being jerked around so much by carriers. Yes folks, this is throttling coding. When we made the AT&T Hacked Carrier Update, this was the first line of coding to be scrapped when the project started. Immediately, through my testing on an AT&T iPhone 5 and iPad 4th generation, there were significant and noticeable results. There is no argueing or disputing that this is clear evidence you are purposely, 24/7, being throttled, even if you haven’t used more data than your authorized to use or that you’ve purchased with your hard earned money. AT&T users, do you think this is fair?

The theory is that Apple limits the capabilities of the device in order to combat the large amount of data/bandwidth iOS device users consume and ease congestion on carrier networks. Brown found signs of throttling data speeds for Verizon and Sprint too. The only carrier that is apparently not limiting the iPhone 5’s capabilities is T-Mobile.

Brown also says “Apple has band preferences set for T-Mobile and AT&T causing signal issues” that could be easily fixed.

Here’s what Brown found in his analysis of the other carriers: expand full story
