Intel X25-M SSD: Intel Delivers One of the World's Fastest Drives

Be sure to read our latest SSD article: The SSD Relapse for an updated look at the SSD market.
No one really paid much attention to Intel getting into the SSD (Solid State Disk) business. We all heard the announcements, we heard the claims of amazing performance, but I didn't really believe it. After all, it was just a matter of hooking up a bunch of flash chips to a controller and putting them in a drive enclosure, right?
The closer we got to release and the more time I spent with competing products, the more I realized that Intel's biggest launch of 2008 wasn't going to be Nehalem - it was going to be its SSDs. If Intel could price them right, and if Intel could deliver on the performance, the biggest upgrade you could do for your PC - whether desktop or notebook, wouldn't be to toss in a faster CPU, it would be to migrate to one of these SSDs. Combine Nehalem and one of these mythical SSDs and you were in for a treat. But that was a big if...Intel still had to deliver.
We already talked about the drives back at IDF. The Intel X25-M and the X18-M, available in 80GB capacities, 2.5" and 1.8" form factors (respectively) with 160GB versions on the way. Today we are allowed to share performance data and pricing information, one of which is more impressive than the other. Intel will be selling the X25-M at $595 MSRP through OEMs and channel vendors, although I hear the street price may be lower.
Both of the -M models are based on Intel's MLC flash, while a X25-E using SLC flash will be due out by the end of this year. I'll detail the differences in a bit.
The pricing is rough, that puts Intel's X25-M at cheaper than SLC drives on the market but more expensive than MLC drives. Your options are effectively to get a 128GB MLC drive, an 80GB Intel X25-M or a 64GB SLC drive. But as you can expect, I wouldn't be quite this excited if the decision were that easy. Over the next several pages we're going to walk through the architecture of a NAND flash based SSD, investigate the problems with current MLC drives (and show how the Intel drive isn't affected) and finally compare the performance of the Intel drive to MLC, SLC and standard hard drives (both 2.5" and 3.5") in a slew of real world applications.
If you want to know the ending first I won't make you wait. Intel absolutely delivered with its first SSDs. After I completed my initial testing of the drive I sent AnandTech Senior Editor, Gary Key a message:
"I think Intel just Conroe’d the HDD market."
Honestly, within 6 months I'd expect it to be just as important to have one of these drives in your system, as your boot/application drive, as it was to have Conroe in your system back in 2006. The only issue here, the only problem I have is the price. I was hoping for something much lower from Intel and although the pricing is justified based on the performance, it ensures that the X25-M like most high performance SSDs, remains a luxury item.
While the X25-M isn't the world's fastest storage device across the board, it is among the fastest. And in the areas that it does dominate, it does so unbelievably well. The other great thing? You’ve got one of the world’s fastest hard drives, and it can fit in your notebook.
Let's get to it.

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.
