The SSD Relapse: Understanding and Choosing the Best SSD

Why You Absolutely Need an SSD
Compared to mechanical hard drives, SSDs continue to be a disruptive technology. These days it’s difficult to convince folks to spend more money, but I can’t stress the difference in user experience between a mechanical HDD and a good SSD. In every major article I’ve written about SSDs I’ve provided at least one benchmark that sums up exactly why you’d want an SSD over even a RAID array of HDDs. Today’s article is no different.
The Fresh Test, as I like to call it, involves booting up your PC and timing how long it takes to run a handful of applications. I always mix up the applications and this time I’m actually going with a lighter lineup: World of Warcraft, Adobe Photoshop CS4 and Firefox 3.5.1.
Other than those three applications, the system was a clean install - I didn’t even have any anti-virus running. This is easily the best case scenario for a hard drive and on the world’s fastest desktop hard drive, a Western Digital VelociRaptor, the whole process took 31 seconds.
And on Intel’s X25-M SSD? Just 6.6 seconds.
A difference of 24 seconds hardly seems like much, until you actually think about it in terms of PC response time. We expect our computers to react immediately to input; even waiting 6.6 seconds is an eternity. Waiting 31 seconds is agony in the PC world. Worst of all? This is on a Core i7 system. To have the world’s fastest CPU and to have to wait half a minute for a couple of apps to launch is just wrong.
A Personal Anecdote on SSDs
I’m writing this page of the article on the 15-inch MacBook Pro I reviewed a couple of months ago. I’ve kept the machine stock but I’ve used it quite a bit since that review thanks to its awesome battery life. Of course, by “stock” I mean that I have yet to install an SSD.
Using the notebook is honestly disappointing. I always think something is wrong with the machine when I go to fire up Adium, Safari, Mail and Pages all at the same time to get to work. The applications take what feels like an eternity to start. While they are all launching the individual apps are generally unresponsive, even if they’ve loaded completely and I’m waiting on others. It’s just an overall miserable experience by comparison.
It’s shocking to think that until last year, this is how all of my computer usage transpired. Everything took ages to launch and become useful, particularly the first time you boot up your PC. It was that more than anything else that drove me to put my PCs to sleep rather than shut them down. It was also the pain of starting applications from scratch and OS X’s ability to get in/out of sleep quickly that made me happier using OS X than XP and later Vista.
It’s particularly interesting when you think of the ramifications of this. It’s the poor random read/write performance of the hard disk that makes some aspects of PC usage so painful. It’s the multi-minute boot times that make users more frustrated with their PCs. While the hard disk helped the PC succeed, it’s the very device that’s killing the PC in today’s instant-on, consumer electronics driven world. I challenge OEMs to stop viewing SSDs as a luxury item and to bite the bullet. Absorb the cost, work with Intel and Indilinx vendors to lower prices, offer bundles, do whatever it takes but get these drives into your systems.
I don’t know how else to say this: it’s an order of magnitude faster than a hard drive. It’s the difference between a hang glider and the space shuttle; both will fly, it’s just that one takes you to space. And I don’t care that you can buy a super fast or high flying hang glider either.

Anandtech has always been known for its in-depth analysis, you're just looking for a simple review list. I much prefer these detailed articles than just hearing the list of performance and simple recommendations that most people can write if provided the proper hardware.I love how Anand always writes excellent, very well detailed articles that are still SIMPLE to understand. A number of other sites may offer some similar levels of detailed but are sometimes a bit too difficult to comprehend without a background in the same field.

Anand,I read your long series of articles on SSDs today, and just wanted to say thanks for writing the most informative and interesting series of tech articles I've read in years. I've been avoiding SSDs because my first experience with one was horrible. The sustained transfer rates were no better than a traditional hard drive, and the system halting for several seconds on each random write operation was too much for me to stand.
I was so sick of the SSD coverage that I was reading on other websites because none of them seemed to answer my biggest question, which was "Which SSD won't bring my system to a screeching halt every time it needs to write a little data?"
Thanks for answering that question and explaining what to look for and what to avoid. It sounds like it's a good time for me to give SSDs another shot.

That about sums it up: disappointment. Although this was a top-caliber SSD article, like i have come to love and expect out of anand, this article didn't make my buying decision any easier as all. In fact, it might have made it more complicated.I understand Intel, Indillinx, and Sandforce are good, but there are so many drives out there, and most suck. This article was amazing by most standards but the headline should be changed: removing the "Choosing the Best SSD."
Maybe "Choosing the right controller before sorting through a hundred drives" would be an appropriate replacement.
Do i still go with the intel 160 X-25m G2?
Do I get the addon Sata 6g card and get the C300?
Do i save the money, and get an indillinx drive? Is the extra money worth the Intel/C300 drive?
These are the main questions enthusiasts have, and while this article contained a great overview of the market in Q3 2009, SSD Tech has progressed dramatically. Only now, i think, are we getting to the point that we could publish a buying guide and have it last a few months.
I trust Anandtech, i just wish they would flat-out make a buying guide, assign points in different categories (points for sequential read/write, points for random read/write, points for real-life performance or perceived performance, points for reliability, and points for price.). Take all of these points, add em up, and make a table pls.
A few graphs can help, but the 200 included in each article is overwhelming, and does nothing to de-complicate or make me confindent in my purchase.
It's great to know how drives score, how they perform. But it's even important to know that you bought the right drive.

This article is dated 8/30/2009!!!!It’s ancient history
Since then newer, faster SSD’s have been introduced to the market.
And their firmware have all been updated to address known past issues.
This article is completely irrelevant and should be taken down or updated.
I’m constantly amazed at how old trash info is left lingering about the web for search engines like Google to find. Just because Google lists an article doesn’t make it legit.

Actually I am trying to find a reason to use SSD.1. Server Environment
No matter it's a webserver or a SQL server, I don't see a way we can use SSD. My SERVER comes with plenty of RAM 32G or 64G. The OS/start a little bit slow, but it's OK, since it never stop after it's started. And everything is loaded into RAM, no page file usage is needed. So, really why do we need SSD here to boost the OS start time or application start time?
For SQL server database, that's even worse. Let's say I have a 10GB SQL server database, and it grows to 50GB after a year. Can you image how many random writes, updates between the process? I am not quite sure this will wear off the SSD really quick.
2. For desktop / laptop, I can probably say, install the OS and applications on SSD, and leave everything on other drives? And even create page file on other drives? As I feel SSD is only good for readonly access. For frequent write, it may wear off pretty quick? I am doing development, I am not even sure I should save source code on SSD, as it compiles, builds, I am sure it writes a lot to SSD.
So over all, I don't see it fits in Server environment, but for desktop/laptop, maybe? even so, it's limited?
someone correct me if I am wrong?

Hi peopleI'm up for getting a new Macbook pro with ssd.
BUT i heard somthing about, that the 128gb ssd, for apples machines, was made by samsung. I was ready to buy it, but now that i've heard that first of all "apples" ssd's is much slower that they others on the marked. Then i read this. So now i'm really confused.
What shoud i do?
buy apples macbook pro with 128gb ssd
or should i buy it without and replace it with an other ssd? thoughts? plzz help me out
thanks
Thomas

Why Sandforce controllers are ignored?I’m extremely disappointed with the compiler benchmark. Please test .NET (With lot of classes source files and dependencies). It seems like nothing speeds up compilation. No CPU, no memory, no SSD. It makes nonsense.

I found this article of very good quality.I was looking for a similar article about express card SSDs using PCIe port, but found nothing about their performance for rewrite.
The best I found is this review http://www.pro-clockers.com/storage/192-wintec-fil... saying nothing about it.
Expresscard SSDs would allow good speed improvement/price compromise : buying a relatively small and cheap one for OS and softwares, while keeping the HDD for data.
Has anyone some info about it ?
Best regards,
Sylvain

Well I was curious about the flash in my Agility 60GB so I opened it up and noted a different Intel part number - mine consisted of 8 x 29F64G08CAMDB chips whereas the pic above shows the 29F64G08FAMCI. I wonder what the difference is?-Paul
