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.

The Fresh Test

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.

    Hi,
    try RamDisk Plus 11 from SuperSpeed.
    (http://www.superspeed.com/desktop/ramdisk.php)
    I use it on Xp pro 32 bit with 30 GB OCZ Vertex and 8 GB RAM. All above 3.2 GB is configured for swap and temp. Works perfectly and no visible SSD performance degradation after about 10 months.
    Greetings.

    would explain to me how did you install it?

    the ssd as a second drive or did u install all the program on the ssd and use the hhd as a second?

    thanks in advance!

    SWAP file is one of the most important speed bottleneck on windows.

    it writes frequently to disk, so consumes the read write cicles of the disk, reducing his useful life.

    But you are not buying space storage when you buy SSD. You are buying speed, so it makes nosense to buy an expensive SSD, and then remove from it all the activities that need the speed and are bottlenecks.

    you buy a SSD to do the fastest SWAP. keep it on SSD.

    Also, drive indexing permanently does a lot of reads, but it does not matter if the disk is fast. Drive indexing is like a little local google. If you disable it, and then search for all the files with a given text on it, searching the entire disk takes longer than just read an indexing.

    Those activities consume the useful life of the disk, but at the time the disk gonna need replacement, (5 years, maybe), this disk gonna need replacement anyways, and new SSD gonna be dirty cheap, so it makes no sense to disable swap, temp files, and indexing.

    On other side, prefetch, superfetch and defrag most probably are better disabled under SSD.

    Pehu, I know this much after your posting, but I was curios what you ended up doing for swap.
    8GB of RAM almost seems like swap may not be needed, unless you have several memory-hogging apps open.
    Hope you still like your SSD. I'm looking at getting one soon, and agree this was an excellent article!

    First: I submit to the importance of random 4k for ssd.
    Second: Over the years I have highly valued the articles of Anand. It is remarkable to see such detailed and enthusiastic information.

    Now I have a few questions, following the general impact of this work.
    Some observations first:
    Following an article at Toms of a ssd article the 6 of September. The author was called a “Moron”, primarily as the random 4k synthetic bm was missing. The author was giving a different opinion on the indilinx vs intel, in the desktop sector, compared to Anand, giving more weight to transfer vs iops.
    In an discussion about a Kingston V-series review, one said that he would take the indilinx ssd any day because it was “750 times faster” – an argument based on iops.
    Another remark I have read several times is: “The Intel x25-M g2 is the only drive to get”.
    Another is: “I would like to buy the Dell xx, but it has an Samsung controller so its of no use”.

    I think it is time to stop, and make sure there is reason in what is happening for normal desktop use.

    Do we have blind test where to tell the difference between the Intel, Samsung and Indilinx?
    What is the actual real world bm fx. Win7 boot times for the 3 controlers?

    There is something called good enough. When is 4k random read/write time enough, to not notice any subjective improvement afterwards in win7? Could it be fx. 10M/s?

    The ssd is the best thing happening since 3d gfx, but I think we should enjoy what is happeing right now, because this time, could be the turning point where we soon are focusing on small differences.

    Anyone knows what´s the next big thing?

    Random 4k and its relevance for desktop use is really the main topic for me, too.
    If I assume that I only use the SSD for the OS and software and save my data on other, much less expensive HDDs, I doubt very much that this discussion is worth it. The Samsung SSD then suddenly looks not so bad at all and much cheaper...
    The next big thing for me would be an OS starting up in 5 seconds, like the OS we had in the 90s...making SSD obsolete.

    I agree completely. I think that human beings can nottice the difference between a hard disk, and a non bad SSD, because the difference is too large, but over "good enough", it does not matter much if the SSD is 2X or 4X faster in 4Kb random R/W.

    But mine is just an opinion, and I don't have good data to test it. I would like to read an article with repeatable testing on human perception.

    I haven't read all 254 comments (yet) but I'd like to add my thanks to everyone elses for the comprehensive and illuminating article. This, along with the previous AnandTech SSD articles have increased my understanding of SSD's immensely.

    Thanks again!

    Anand,

    A couple of guys from HotHardware.com pointed me at your SSD article, and it allowed me to make an informed decision. Thanks!

    I wanted to speed up one game in particular (World of Warcraft) as well as routine OS tasks and web browsing. I think an SSD will do a bang-up job on at least the first two. The one I decided upon was the OCZ Agility 60 GB, which offers some growth room; I currently have 40 GB on my system drive. I know the Intel has better numbers, but I was able to get the OCZ for $156 after a rebate, which translates to decent performance at a price I can justify. (For the curious, it's available from TigerDirect for $184, and OCZ is giving a $30 rebate.)

    Even though my system build is still months away, this should be usable on my old clunker as well. Very nifty!
