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.

I think the question was: how much more performance is left untapped by current controller designs? The JMicron issues are a limited case, what will truly be telling is what happens when we see Intel vs. Samsung with SLC drives...The dominating the charts line was in reference to the Crysis results. If you've ever run the Crysis GPU bench you'll know that it is extremely disk intensive (particularly the first run). As I mentioned in the article, it over emphasizes the importance of disk performance but that's not to say that the results aren't valid.
I do see your point however, let me see what I can do about clarifying that statement.

Ok, I guess I missed the JMicron 'thing', but to be perfectly honest I dislike *anything* JMicron and try to avoid them whenever possible. I guess I am just so interested in these Intel drives, I just tuned everyting else out. However, I did read what you mentioned about 'trouble-shooting' the JMicron MLC issue.Never ran Crysis, and do not plan on running it anytime soon if ever, but I am somewhat of a hardcore gamer.
Keep up the good work, and PLEASE do keep us informed on at least these Intel SSD drives :)

If the achilles heel of the JMicron MLC is the random write speed, why couldnt a ram buffer be used to cache writes? Sure this would cause a serious problem if the power went out, but thats an issue some would be willing to live with.I'm fairly sure vista has an option for this in the device manager in the properties tab of a drive - "enable advanced disk performance". I wonder if that would have any effect on the results?

Yet more proof that JMicron products are shit.ggordonliddy - Monday, September 8, 2008 - link
For the love of all humanity: If you are going to write for a living, please learn basic comma usage!It is NOT okay to just stick a comma in the middle of a sentence anytime you want. And it gives readers a headache.
Here is just one of numerous examples of improper comma usage I've seen so far (and I've only gotten to the 3rd page!):
"Intel certifies its drives in accordance with the JEDEC specs from 0 - 70C, at optimal temperatures your data will last even longer [...]"
The comma before "at optimal" should be replaced with a semicolon or a period (I prefer the semicolon).
Did you actually pass your English classes? I'm guessing that you probably did and you are just a product of our miserable public school system that refuses to hold students to any real level of accountability.
(And BTW, your quoting system is broken. When I enter text in the Quote Text dialog and click OK, nothing new appears in the Comment compose field.)

Honestly man, you need to seriously relax. My personal rule of thumb for grammar is does the mistake make the understanding of the sentence difficult to comprehend.Writing something like, "Intel certifies its drives in accordance with the JEDEC specs from 0 - 70C, at optimal temperatures your data will last even longer [...]", while not grammatically correct is completely readable.
If it was something like, ""Intel certifies drives to accordance with the JEDEC specs from 0 - 70C, at optimal data your temperatures will last even longer [...]", now you have a legitimate beef.
The former can easily be forgiven, the latter makes my head hurt when I read it. Trust me, whatever you do, do not go to Dailytech.com and read the articles. Those even I get annoyed at frequently and I'm very forgiving.

You're quite right, thanks for the heads up :) Some of the article was directly from my notes while I was working on the tests, so that's one source of unpolished bits. I know I'm far from perfect, so I do appreciate your (and anyone else's) assistance.Thanks :)

Thanks for posting, Anand. I see you're already aware of the problem, but I wanted to throw my two cents in.What is the usual editing process? I think a once over by a second set of eyes would have caught the bulk of the grammatical errors.
Of course, the ultimate issue isn't commas. It's readability. However, the problem was bad enough that I'm making this comment without having even gotten through the first page of this article.

I'm often the content editor for posted articles, but often we skip that stage due to late nights and schedules. Doing a final thorough edit can require a couple hours (edit and then HTLM-ize), and when someone finishes an article at 5AM or whatever and it's an NDA type piece, delaying it any further is usually not desired by the readers or us.I do read all posted articles, and often I take the time to go through and fix any noteworthy errors. A few misplaced commas don't really detract from a 5000 word article, however, and depending on what else is going on I may or may not edit the text. If anyone takes the time to point out specific errors, i.e. "on page 3 you write "...." they always get corrected - at least if I see it. General complaints are much more difficult to address though, i.e. "You used passive voice and therefore you must DIE!" LOL.
I know personally that when you write a long article with lots of testing, certain thoughts tend to appear in multiple places and the final result isn't always as coherent as I would like. Trying to "fix" problems relating to flow and readability is difficult at best, and requires more time than we generally spend. If anyone wants to make specific suggestions, though, we're open for input as always.
Perhaps it's useful to compare the process to print publications. Magazines usually have several editors on staff whose job is solely to edit other authors' work; I can say that we don't have anyone at AnandTech in that position these days. (I edit some of the articles, but not all, and even then I make mistakes.) That's probably why we have more typos than magazines, but then we provide far more thorough coverage as well. Last I saw, most magazine hardware reviews end up being one page and ~1000 words, with a couple charts.
At the end of the day, I get most of my detailed information from the internet. Magazines might be more grammatically correct, and they make for great toilet reading, but I don't generally depend on them as a source of credible information. I'd say it's safe to say we won't see such an in-depth exploration of SSD performance and issues in any magazine. [Now I have to prepare to have someone point me to an article in some magazine that does exactly that.]
Cheers,
Jarred

Then I guess I should point you to an article in last month's issue of my favorite data storage magazine.http://www.solidstatedisksmonthly.com/2008/08/ever...">http://www.solidstatedisksmonthly.com/2...erforman...
Unfortunately, their website seems to be down at the moment, but keep checking it, I'm sure it'll be back up soon (and don't be fooled by the article's title. It's actually only 23 pages without the ads).
