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

Overall System Performance with SYSMark 2007
Our first test is the full SYSMark 2007 benchmark suite. It's a system-level performance test that measures performance based on average response time, making it a great candidate for our SSDs, which should provide pretty low response times, at least compared to standard mechanical disks.
The Intel X25-M does very well here, just edging past the fastest desktop drive on the market and outperforming all other mechanical disks in its own 2.5" form factor. We saw a 15% increase in overall performance under SYSMark compared to the Seagate Momentus 7200.2; to get that sort of speed boost on a notebook would take Nehalem otherwise.
You'll notice that I threw in the 150GB Raptor in the mix as well, that's our current CPU testbed HDD. Our Q9450 saw performance go up by 9% thanks to the X25-M, that's more of a performance boost than you'd get by upgrading to a QX9650 and again, this is a system-level test, not disk specific.
Here you also see the problems with the JMicron equipped MLC drives, the Intel X25-M manages to outperform these drives by nearly 30%. The Video Creation test is particularly bad with the Intel X25-M garnering a score nearly 2x of the JMicron MLC drives. We've already established that the X25-M is the only MLC drive that you should consider, this simply helps provide more support.

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).
