Well done Nigel
However I can already tell you this book gives you a heck of a lot of information in an understandable way.
Even on subjects I thought I knew sufficient about, it provided me with some additional information.
Would recommend this book to any IT professional who wants to know more about storage.

There is no doubt that the content in this book is awesome. This book is heavy on theory and does a great job of explaining how the technologies work. I took the exam two days ago and passed (not the greatest score but I'll take it). The materials I used were this book, Pluralsight (which is this book in audible format), and the uCertify package featured on the CompTIA site. I'll give my two cents about the latter and focus on the book at the moment.
An area that the book does not focus on are specifications. Having taken some CompTIA certifications before, I knew the exam would certainly have questions on specifications. For instance (and these weren't questions, just examples), which generation of LTO was WORM first available? Or, what is the maximum distance of 1000Base-LX? The certification exam that I took had a lot of these types of questions and this book contains very little in terms of exact specifications of formats for certain media and technology. While reading the book, I did my due diligence and researched these items on my own as I encountered the subjects. The book also has a lot of errors in terms of typos and calculations (probably from the typos). You should be able to figure everything out and correct the errors on your own from the content in the book, don't let that detract from the book's quality content.
Aside from the specifications, this book did an outstanding job in explaining the theory behind the technologies. The exam I took was heavily sedated with RAID and FC questions (I think I only received one iSCSI question which is odd, I thought I'd see more of them). I felt confident in most of my answers in regards to answering the questions that were heavy on theory and troubleshooting the technologies and felt the questions I missed were the simple yet overlooked questions on specifications and some other miscellaneous questions. I am not disappointed with the book. This book was definitely written by someone who works in the field and knows his stuff. The book reflects upon the material that you'd encounter on an every-day basis and not the unimportant fluff we know is irrelevant such as maximum distance and throughput numbers (unless you're an engineer and designing such technologies).
The content that comes with the book should not be ignored. The exam that comes with the book (downloaded from the web) is actually pretty close to the type of questions you'll see on the exam (in fact, there was one question that was exactly the same on the certification exam from the book's exam). The flashcards, which is always a nice feature, is merely just a 100 words/phrases. I would of loved to see about 300 questions and double the amount of flashcards for materials to properly study. This is what led me to try uCertify. (Note: The author notes the difference of Cumulative and Differential Incremental backups and the conflict between the terms being used, yet has the wrong answer on the exam)
Is the book a good enough source to pass the exam? I guess it would depend on the version of the exam you get (as the % of questions from certain groups are changed with every instance). The version I took I don't think I would of passed, perhaps come close. However, as long as you research the specifications of certain technologies like fiber, Ethernet, and so forth, you should be able to pass.
For my opinion on Pluralsight and uCertify (which does not reflect upon the book), I do not recommend either. Pluralsight is literally just a cut-down version of the book in audio format. However, it may be worth it to sign up for the trial to access the materials that accompany the videos (PDF files of the slides being used in the videos. These work great on a tablet device that you can just flip through anywhere you have downtime for review). uCertify wouldn't of been so bad if the material on the site wasn't old (about 7 years behind or so when compared to the content with the book). It seems like whatever certification that SNIA had back then was simply taken and just rebranded with the Storage+ name. The review material and flashcards are not helpful and its best to just go straight to the practice exams. I will admit that 60% of the questions are simple questions you may encounter (you'd have no problem answering them from the material in Nigel's book), 30% of them are just outdated/not relevant (I do not care about FC-AE and neither does CompTIA) or wrong (I've bashed my ahead against the desk a few times in frustration. There will be questions that have answers that make no sense and easily half the questions have no explanation as to why the answer is suppose to be right), and 10% of the questions present something new and valuable to learn.
Bottom line: Get the book, it is a fantastic resource for learning the technologies, just do some research on specifications (make sure you know your RAID inside/out). Skip Pluralsight (except for the downloadable materials using the free trial). Skip uCertify (unless you can get it cheap. $30 would be a fair price in my opinion).
In general I would recommend this book as it does a good job of explaining the theories behind Storage Management. In regards to using it to pass the Storage+ it's probably the best book you're going to find available right now. Based on my research and what I found in forums, it's one of the most interesting storage books around.
As another reviewer mentioned, it does lack a bit in the specifications department. So if you're only using this book be sure to look up things like LTO specifications, CAT cable specifications, SMF vs MMF cable specifications (OM1, OM2, etc. - this is mentioned in the book), etc. One thing I'll also say is that in the book it's mentioned that the test uses the SNIA definitions for differential incremental and cumulative incremental backups and I believe that the test does use these definitions, however the practice exams that accompany the book seem to use the mainstream definitions, which can be a bit confusing. If you have your Server+ or A+ keep those concepts in mind while studying, basic/common sense stuff like making sure to troubleshoot from the bottom up.
As far as the other things I use, I signed up for the free trail of uCertify and took the pre-assessment test which I thought was helpful. I also signed up for the PluralSight free trial, I didn't really use that, I think I listened to one lesson at most. If you don't pick up things well by reading them, I would suggest PluralSight in addition to this book. The course is done by the author and is basically just a shorter version of what's covered (at least that's what I got from what I listened to). If nothing else you can sign up for the free trial and see if it would help you.
In the end I would suggest you purchase the book. It really is handy and was essential in my success with the Storage+.
You simply cannot go wrong with this book and while I want to skip chapters straight to the backup section (Chapter 11) I just can't. The book is well organized and provides a foundation of information in each chapter that builds on the previous chapter. This allows you to understand storage from the ground up, from the mechanics of HHDs and SSDs, SANs, NAS, RAID, Snapshot, Replication and even Virtual Storage technologies. The list goes on and on but this book is great to say the least.
I also agree with a comment from another reviewer. This book needs to be available in hard cover. For certain this will be a desk reference and a hard cover edition would be nice.
To Sybex and Nigel Poulton ... Thank you. I'm on my way to gaining competence in storage technologies.
