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.

Intel insists it's not an artificial cap and I tend to believe the source that fed me that information.That being said, if it's not an artificial cap it's either:
1) Designed that way and can't be changed without a new controller
2) A bug and can be fixed with firmware
3) A bug and can't be fixed without a new controller
Or some combination of those items. We'll see :)
Take care,
Anand

Another fine article anand :). Keep up the good work.CurseTheSky - Monday, August 31, 2009 - link
This is absolutely the best article I've read in a very long time - not just from Anandtech - from anywhere.I've been collecting information and comparing benchmarks / testimonials for over a month, trying to help myself decide between Intel, Indilinx, and Samsung-based drives. While it was easy to see that one of the three trails the pack, it was difficult to decide if the Intel G2 or Indilinx drives were the best bang for the buck.
This article made it all apparent: The Intel G2 drives have better random read / write performance, but worse sequential write performance. Regardless, both drives are perfectly acceptable for every day use, and the real world difference would be hardly noticeable. Now if only the Intel drives would come back in stock, close to MSRP.
Thank you for taking the time to write the article.

been waiting months for this one.therealnickdanger - Monday, August 31, 2009 - link
Ditto! Thanks Anand! Now the big question... Intel G2 or Vertex Turbo? :) It's nice to have options!Hank Scorpion - Monday, August 31, 2009 - link
Anand,YOU ARE A LEGEND!!! go and get some good sleep, thanks for answering and allaying my fears... i appreciate all your hard work!!!!
256GB OCZ Vertex is on the top of my list as soon as a validated Windows 7 TRIM firmware that doesnt need any work by me is organized....
once a firmware is organised then my new machine is born.... MUHAHAHAHAHAHA

Vertex Turbo is a complete rip off, Anand clearly held back saying it from offending the guy at OCZ.Now the other OCZ models however, could be a different story.

I too love my Vertex. Running these things in RAID0 will blow your mind. I'm just waiting for some affordable enterprise-class drives for our servers.Mike

I loved the first draft of the Anthology and this is a great follow-up. I have been running a Vertex in workstation and laptop for months know and continue to be amazed at the difference when I boot up a comparable system still running standard HDDs.gigahertz20 - Monday, August 31, 2009 - link
Another great article from Anand, now where can I get my Intel X-25M G2 :)
