The SSD Anthology: Understanding SSDs and New Drives from OCZ

The Test
If you’ve managed to make it this far in the article then I owe you a great deal of gratitude. While I’d offer to make you dinner it’d probably be a little impractical, so instead I’ll help you find out how these SSDs perform.
Note that every single benchmark here was run with the drive in a “used” state. Again, I did so by performing a secure erase on the drive, filling it to capacity, then restoring my test bed image over the partition. I can definitely make the drives benchmark faster, but I’m trying to provide performance data that shows you how your drive will behave after you’ve owned it for a while.
To make the benchmarks all that more stressful and realistic, I kept Avast Anti-Virus running and scanning every file accessed in the background of all of my non-suite and non-synthetic tests. Basically everything that was hand-timed. Firmware 0122 is utilized for this review. OCZ recently released firmware revision 1199 that we are testing currently and another release (1275) is expected shortly. We will provide an update if there is a significant difference in performance or the user experience routines.

This is, very likely, the best article I have ever read, period. Online, in magazines, about any subject... this was an absolutely fantastic read. Suddenly, all smoke surrounding SSDs has cleared and the truth shines through in editorial brilliance. It's great to see that at least some computer news sites out there can still cut through the crap and get to the heart of the issue. My already high opinion of AnandTech has risen even further.Thank you for taking the immense time it must have taken to compile and assemble all this information - this article is now a must-read for *anybody* considering purchasing an SSD, and it's just about all the background you could need in one place.
In addition to all the extremely useful general SSD information contained within, the detailing of the issues with the JMicron controllers as well as OCZ's efforts to address the concerns to produce the best product possible (despite the reduced marketability to the uninformed) is reassuring and comforting in a world where tech companies seem more concerned with how much they can deceive their customers instead of producing quality products.
In short, the article is a win on all fronts, thank you greatly for posting it. When I purchase my first SSD (which I'm considering doing reasonably soon) this article, its information and suggestions, and OCZs actions to resolve the issues with its drives will definitely be at the forefront of my mind.

I have to say, I really appreciate the effort and throughness with which you have covered the state of the SSD market today. As an engineer and scientist, I applaud your methods in tracking down and reporting the major issues with SSDs. As a consumer, I really appreciate the timeliness of this article as I was just thinking of putting an SSD in a netbook for a robotics application where mechanical drives are not ideal.Cheers!

That said, one thing I would have like to have seen is some numbers on power consumption for these drives compared to average mechanical desktop and laptop drives.aamsel - Thursday, March 19, 2009 - link
Anyone have a link to the Intel HDD ERASE program that Anand referred to?HolyFire - Thursday, March 19, 2009 - link

AWESOME ARTICLE.The huge difference in read/write flash performance looks a lot like this article: http://www.anandtech.com/memory/showdoc.aspx?i=257...">http://www.anandtech.com/memory/showdoc.aspx?i=257...

Thanks for the orgasmic review.wicko - Wednesday, March 18, 2009 - link
Had a really good read here, thanks for the history and info, Anand. The only thing I don't understand is what the importance of random write is? What kind of task would benefit from high random write speeds (maybe copying many files at once)? I'm tempted to pick up a vertex drive but it depends on whether or not random write will be important for me. But the price... whoa, pretty damn expensive here in Canada.. http://www.ncix.com/products/index.php?sku=36023&a...">http://www.ncix.com/products/index.php?...X120G&am... - $625 for a 120GB!!! I kind of want 2, for RAID0, I have a lot of games installed (steam folder alone is 100GB lol). Might even have to raid 3 of em.. but not for $1800 lol.strikeback03 - Thursday, March 19, 2009 - link
As mentioned in the article, the OS in general makes lots of random writes. Send an IM, it writes to a log. Load a website, it caches some images.AnnonymousCoward - Thursday, March 19, 2009 - link
>I'm tempted to pick up a vertex drive but it depends on>whether or not random write will be important for me.
Keep in mind, its random write is twice as fast as mechanical HDs.
>But the price...
It's only $110USD/32GB.
