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.

Hi all,I report this new review about X25-M, that takes in consideration a comparative with other SSDs and also with HDDs, with several benchmarks ? http://www.informaticaeasy.net/le-mi...m-da-80gb.h...">http://www.informaticaeasy.net/le-mi...m-da-80gb.h...

You said this: For example, let's say you download a 2MB file to your band new, never been used SSD, which gets saved to blocks 10, 11, 12 and 13. You realize you downloaded the wrong file and delete it, then go off to download the right file. Rather than write the new file to blocks 10, 11, 12 and 13, the flash controller will write to blocks 14, 15, 16 and 17. In fact, those four blocks won't get used again until every other block on the drive has been written to onceBy this i understand that a bigger capacity SSD, for instance 320 vs 160 will have more blocks and hence you will need more writes to deplete the number a write cycles the SSD was designed for. So for SSD bigger means even longer lasting. IS this TRUE ?

Can you overclock this SSD?Sendou - Wednesday, February 9, 2011 - link
There are optimization methods available for SSD's which can mitigate performance loss through genuine usage over time.One such is Diskeeper's HyperFast Technology.
There is a white paper regarding HyperFast available at:

I read the pdf article you linked from Diskeeper.Based on the information Anand has given in his articles about Intel's technology, Diskeeper's "whitepaper" sounds like crap advertising by a company who's afraid their technology might be considered not only useless but detrimental to use with SSDs. I'm inclined to agree since Diskeeper's own results show a 4x write loss by just *one* "optimization" while Anand's article clearly suggests that the proper design (which he says Intel has accomplished) eliminates the need for Diskeeper's service.
Until I find more thorough examination of the facts, Diskeeper's remarks make me distrust them.
On the other hand, Anand's article definitely sounds not just like a puff piece for Intel, but qualifies in my mind as advertising. Wonder how much money Intel has spent on Anandtech? That's not to suggest that anything is misrepresentative (well, it wasn't meant to sound that way, but keep reading and you'll find the one-sided praise will later be partially retracted and I don't know the end of the story yet), but we all know that advertising always leaves out the negatives.
(Reviews shouldn't sound like advertisements but anyone who's been reading magazine reviews for 30 years knows that's frequently the case. The reviewer's bills get paid by the manufacturers' of the products he's reviewing. But, the reviewer is objective of course. It's a matter of journalistic integrity. Yeah, I believe that. Don't you?)
One such negative was the promotion of the life of the drive. "20GB a day for five years"? Anand praises Intel for multiplying that by five to "100GB a day for five years" but then tells us that they'll only guarantee the drive for three years and has the audacity to suggest we'll likely have a recourse "if we can prove" ... -- how is anyone going to prove how many GBs a day they put on their computer? The annoyance of trying to keep track is not something 99% of people would do.
Did you do the math to see how long it takes to write 100GB to a drive with a write speed of 200MB/s? Eight minutes and twenty seconds is all it takes.
Well, that's great if all you use your computer for is reading articles, checking the news and sales prices and sending email. The drive should last as long as your computer. But if you love video (who loves video???), it's a different story entirely.
There's another negative that, though first denied, eventually was acknowledged. More than six months later, Anand reports back and says essentially, 'Intel is still the best but the performance does degrade with time and I don't know why.' If he's explained it since then, I've yet to read it.
So, for those just reading the article, don't get so encouraged that you start drooling. The article has a tendency to make one think, "What am I waiting for? I want one of these puppies!" Unfortunately, Intel's technology isn't as rosy and bulletproof and Anand made it sound.

I hope you do some benchmark on Samsung's new 256GB SSD. Hopefully it's as good as Intel's.kevonly - Friday, November 21, 2008 - link
its read/write speed is 200/160 mb/s. Will it sustain that speed in a multi applications running environment??kevonly - Friday, November 21, 2008 - link
sorryread/write speed is 220/200 mb/s.

Legacy OS like Windows Vista, XP, and Applications like Microsoft Office 2003, 2007, etc. have built in, inherent flaws with regard to SSDs.
Specifically, optimizations of these OS for mechanical hard drives like superfetch, prefetch, etc. tend to slow down, rather than help performance and is unnecessary to speed up reads in an SSD, but slow it down with unnecessary writes of small files, which SSDs are slower than a regular hard drive.
Things like automatic drive defragmentation with Vista does nothing for SSDs except to slow them down.
Properly optimized, even low cost 2007 generation SSDs test out as equivalent to a 7200 rpm consumer grade drive, and typical SSDs made in 2008 or later tend to outperform mechanical hard drives.
The tests done here have done nothing to "tweak" the OS to remove design hindrances to SSD performance, and thus, have no validity or technical merit.
The test, as presented, would be similar to installing a 19th century steam engine on a sailing ship, and observing that it is rather slow ---- without mentioning the drag and performance hits caused by the unused sail rigging, masts, etc.
See the discussion here for a detailed discussion of SSD performance tweaks and what it takes to make them perform well with legacy OS and Applications.
