The Killer App: Multitasking Performance
Here's where things get interesting. I ran two tests, in one I extracted a 5GB archive and tried to run Photoshop after 30 seconds of extraction and in the second test, I extracted a 5GB archive and tried to scan my system for viruses using NAV 2008. Simple enough, right? I'm reporting the times of each task individually.
The extraction task took the longest to complete but the standings speak for themselves:
Here's one area where the Samsung SLC based devices actually come out ahead, by a good margin. The Samsung SLC SSD finished the extraction in 102 seconds, compared to 161 seconds for the X25-M. Even the VelociRaptor did better here at 116 seconds, but remember you need to look at both tasks for a complete picture:
Launching Photoshop took 5.2 seconds for the Samsung SLC SSD, it was like we weren't even running another test in the background. The X25-M did fine at 12.2 seconds and the VelociRaptor was much slower at 27.3 seconds. The JMicron based MLC drives didn't do too bad here either, although they were a little slower than Intel's MLC offering.
The real stress test was this next multitasking scenario. Quite possibly one of the most annoying thing about viruses is having to run real time scanning and protection software all the time, especially with a traditional HDD in your system. The extraction task is the same as before, but the other task is a full system scan in Norton Anti-Virus 2008. I timed both:
The WD 1TB drive would always complete the extraction task quicker than all of the other drives, but paid the penalty in the scan test (which is why you have to look at both charts for a full analysis). The Samsung SLC drive is still the overall winner here, followed closely by Intel's X25-M. The JMicron based MLC drives do horribly here, taking over twice as long to complete as Intel's MLC.
The mechanical disks however do a lot worse. While the Intel X25-M took 3.5 minutes to extract the 5GB archive, the VelociRaptor took over 17 minutes. The Seagate Momentus 7200.2 took over 23 minutes!
Let's look at the NAV results:
The X25-M took around 5.3 minutes, the Raptor needed more than 23 minutes and Seagate Momentus made me wait over 40 minutes. It's these sorts of usage scenarios that really make SSDs worthwhile, and they are the most realworld you can get. When we started looking at real world performance the PCMark Vantage numbers may have looked a bit ridiculous, but by now you should see that they are more of the middle ground when looking at performance of these drives.

This is by far the best article I have ever read about SSDs... Anand you ROCK!!! and EVERYONE at ANANDTECH ROCKS!....Great article... Thank you........ you just saved me from spending $99 on a pretty much useless SSD.

I noticed that ocz have released core v2 series of their ssd. It seems to come in a different size configurations than its 1st gen product, can you confirm if this is based on the same controller as its 1st gen product Anand?Also, i would love to see some ssd raid action since ssd does not lose its data when the array fails. I'm more interested to see if there is other limiting factor when you raid with such fast ssds, such as the motherboard chipset itself. If raiding two of those cheap $99 core 32gig ssd helps to reduce the write bug, it might be worthwhile buy, which was something i was thinking of doing till i read the review here.
And might i say, great review indeed Aanad.

Hi there. There is a discussion in the OCZ support forum aboutthe test results published in this article and the OCZ support
staff is thinking that you've got a faulty drive. Check here:
http://www.ocztechnologyforum.com/forum/showthread...">http://www.ocztechnologyforum.com/forum/showthread...
Is there any chance you can re run the test with another
Core drive or Supertalent/Patriot JMicron JMF602 victims?
Thanks.

I posted results with a newly arrived Core drive straight off the shelf from Newegg in that thread. No changes to our initial results, although I will try a different controller later this week.Anand Lal Shimpi - Tuesday, September 9, 2008 - link
In total I have four drives based on the JMF602 controller: one from OCZ, SuperTalent, Patriot and Silicon Power.Of the drives, the OCZ Core is the oldest. If you look at page 9 in the article I've got a table that has the SuperTalent, Silicon Power and OCZ Core drives in it. The Silicon Power and SuperTalent drive both perform worse than the OCZ.
The situation gets more interesting if you look at the Iometer results for the drives, which I didn't publish in great depth but I did run internally. Average write latency goes down tremendously on the SuperTalent drive, but max latency more than doubled. I suspect that the SuperTalent drive may use a newer version of the JMF602, but the result is a reduction in real world performance - at least in the test cases I ran.
The inability to complete an OS install also applies to other drives. As I mentioned in the article I had the same problem with the SuperTalent MLC drive in OS X.
While there are undoubtedly ways of attempting to lessen the impact of the JMF602's poor design, I believe only a new controller will actually completely address these problems.
Take care,
Anand

This is why I love your website. Lots of your articles are so in-depth they make me think I'm reading some grad school journal that I should be paying money for.I actually first saw the Intel SSD article on TomsHardware, but didn't even bother to read it because I imagined it was going to say something like "OMG INTEL SSD ROX LOLZ SO MUCH FASTER THAN OTHER HDS"
I come here expecting to get a detailed analaysis, and that's always what you provide! Thank you so much.
My only gripe is you seem to have skipped a very basic test- dragging and dropping large files! You combine extracting files with other tests but you don't have any basic drag + drop tests I saw.
This rocks for the computer industry though. I personally couldn't believe so many people were buying the existing SSDs. This new Intel stuff looks like something that would actually make an improvement without compromises. I could certainly live with the capacity, I'm still running a 36GB raptor for my boot drive. Hah.

I'm proud to be working for the company producing these IC's. Nice work on the article.therealnickdanger - Tuesday, September 9, 2008 - link
It would be very nice to see where on all these charts the best 5400RPM 2.5" SATA drive would sit. Most laptop users have 5400RPM drives, so this would be MOST EXCELLENT to see the benefits of all these drives in comparison - especially the now "crappy" JM-based MLC drives.johncl - Tuesday, September 9, 2008 - link
I must congratulate Intel for adressing the issues with MLC and creating a brilliant product. Also thanks to the author of this article to point to the problem of MLC that seems to go by unnoticed by so many benchmark review sites.The initial price from intel is suggested retail price so I guess in a short while this should come down a bit, as its a bit over the top. As the author says, at around $400 this is a no-brainer for an enthusiast considering the improvement you will experience on your system. This is for me the most important advancement in computer technology in the last years and we are just starting to see the advantages of it. Besides the person sitting behind the keyboard, the slowest thing in your computer is the harddisk. You can swap CPUs and GPUs to your hearts desire, but eventually, percieved performance of a computer often boils down to how fast you get data in and out of system memory. SSDs will fix this technological void we have had for all these years with mechanical disks.
In general its about time we get rid of all mechanical parts in a computer, including fans. We need good cooling solutions built into our systems that rely on other means than rotating motors. If it means to stop the CPU speed race, then by all means do that, lets try to get todays performance but passively cooled. The SSD will walk hand in hand with this new trend in computing so we can get truly silent workstations. Amen to SSDs!

I'm looking into creating a small multimedia PC where by I'll be archiving all my DVDs to DivX and running them through the PC instead of a DVD Player.Would I see any benefits in performance and acoustics (I don't want any noise from the PC interfering with my viewing) by having the OS on the Intel MLC SSD while storing the movies on a mechanical HDD?
Essentially I want to be able to sit down and browse my movies then pick one and watch it without having to worry about loading/transfer times and noise levels.
