Fusion Drive

macOS Sierra Includes a New Apple File System, APFS

June 13, 2016 by Stephen 3 Comments

Although not discussed in today’s keynote, Apple is adding a new “universal” filesystem to iOS and macOS. Apple File System (APFS) will likely replace HFS+ as the default filesystem for Macintosh computers, iPads, and iPhones and brings a wealth of modern features. But judging from the initial developer documentation, that’s not going to happen for a few more years. And there’s still much confusion about how APFS and CoreStorage, introduced in Mac OS X 10.7, will interact.

Is Apple’s Fusion Drive a Hybrid HDD or Tiering Software?

October 23, 2012 by Stephen 7 Comments

This morning, Apple introduced the new iMac, with a build-to-order storage configuration called “Fusion Drive”. But what is Fusion Drive? Although it could be an off-the-shelf hybrid drive, I believe it is a software driver in Mac OS X.

GPS Time Rollover Failures Keep Happening (But They’re Almost Done)

This is week “1111111111” in the GPS system. Tomorrow morning it will roll over to week “0000000000”. How well will various systems handle this change? Not well, judging by what we’ve seen so far!

Ranting and Raving About the 2018 iPad Pro

I remain enthusiastic about the iPad Pro, despite getting a scratched screen and my concerns about durability. It’s a worthy successor to the original and offers enough improvements that I’d recommend the upgrade for just about anyone who uses their iPad for serious work. It’s still not yet a laptop replacement, but this is due more to a lack of desktop-class software for iOS than anything in Apple’s control.

Scaling Storage In Conventional Arrays

November 19, 2013

It is amazing that something as simple-sounding as making an array get bigger can be so complex, yet scaling storage is notoriously difficult. Our storage protocols just werenâ€™t designed with scaling in mind, and they lack the flexibility needed to dynamically address multiple nodes. So my hat is off to these companies and others who have come up with clever ways to maintain compatibility while scaling out beyond the bounds of a single storage array.

Instapaper for iPad and iPhone Enhances My Web World

June 1, 2010

One of my favorite iPad and iPhone apps is Instapaper. Like the iPad itself, Instapaper seems almost foolishly simple and derivative until you experience it. Then it becomes something else entirely: A product so useful you may ask yourself “how did I ever get along without this?”

Hands-On Review: Unicomp Spacesaver M Keyboard for Mac

July 3, 2012

I would not hesitate to recommend the Unicomp Spacesaver M to Macintosh users used to an original IBM Model M, and I am admittedly a tough customer. I wish that Unicomp would update their website, packaging, logo, and keyboard graphics, but none of this really matters as your fingers press the keys. If any keyboard is worth $100, it is the Unicomp Spacesaver M!

Review: American Standard’s Champion 4 Toilet Flushes Almost Anything

July 31, 2012

Although most crappers are crap, plumbing companies like American Standard are hard at work innovating to eliminate the excrement. The current champion is fittingly called the Champion 4, and I have purchased, installed, and tested two examples of the type. The Champion is engineered to reduce the most common causes of clogs, and it has proved effective and “hands-off” in my real-world testing.

What More Could Alan Turing Have Accomplished?

October 7, 2012

Many of you have probably heard the name of Alan Turing, but most of those probably don’t appreciate the extent of his contributions. To say that he invented the modern world is an overstatement, but he did dream up the computers we see around us today, and helped win World War II in the process. But the story of Alan Turing is as much about exclusion and defeat as it is of genius.

Why Are PCIe SSDs So Fast?

June 12, 2013

The world of storage can be confusing, with obscure terms hiding massive differences in technology and performance. Such is the case for the latest PCI express SSDs: They are much faster than traditional SAS or SATA SSDs, but many aren’t sure exactly why. In this article, I will try to explain the real difference.

Frequent Flier Kung Fu for Novices

March 12, 2012

If you’re careful, even an infrequent flyer can rack up valuable points and maybe even elite status. But don’t do anything foolish, and don’t be fooled by the promises of first-class treatment. Even top-tier frequent flyers sit in coach most of the time!

Preserving Your Credibility Is Your Prime Directive

June 4, 2012

I hope this post isn’t too “out in left field” but I thought it needed to be said. Independent social media has evolved into a powerful mechanism to influence belief, behavior, and (yes) buying. I take my little dollop of influence very seriously, and feel an incredible responsibility to live up to the trust placed in me by others. I will try every day not to let you all down!
