AS-SSD Incompressible Sequential Performance

The AS-SSD sequential benchmark uses incompressible data for all of its transfers. The result is a pretty big reduction in sequential write speed on SandForce based controllers.

Incompressible Sequential Read Performance - AS-SSD

I'm not entirely sure why the Octane does so well here when it's unable to deliver these sorts of numbers in Iometer. The big takeaway is that performance doesn't suffer when you throw incompressible data at the controller.

    Anand, do you have any insight into how the SSD industry's volume breakdown goes WRT size?

    I would be shocked if drives > 128GB made up more than 5% of shipments of consumer-class SSDs. I realize that hardware vendors want their product seen in the best possible light, but this 512GB drive might move a couple thousand units total globally whereas the 128GB version might see a couple orders of magnitude more.

    I echo both the request-for-info-on/suspicion of the breakdown in shipments between 128gb models and 512gb models. I also very much echo the desire for more reviews of 128gb drives.

    I get this is what you get sent, but one of the reasons I love Anandtech is that you guys will actually play hardball with the manufacturers. I'm not telling you to refuse to review 512/256gb drives unless you're sent a 128gb model too, but at the same time I doubt you'd only review Extreme Edition CPUs or dual-GPU video cards.

    Thanks a bunch Anand, it's amazing how the perception for OCZ has changed, I remember the days when it was a "stay away from" company. Personally I still haven't bought an OCZ product after getting stuck with dead RAM modules (one outright, one with errors) years ago and having no recourse.

    Still, competition is good, and OCZ has done a lot to bring prices down for SSDs. Hope they succeed in the long term. I was also really tentative about the Indilux acquisition, but so far it's a definite success.

    pretty much all the OCZ memory modules i had over time died prematurely. Bad luck i guess.

    I own 4 1GB modules that are a good 5+ years old, all still work fine.

    Well I do not know how much it has changed overall I would say I still have a negative view of OCZ. They just seem to be a decent marketing machine but they put out alot of garbage. They constantly have sales on bad products which people jump on to try and then get burned. Right now and for months their SSDs which have reliability and firm ware issues are all going on sale for hard to resist prices. I had ram from them that while it still works had a sticker that was so thick it had to be removed in order to fit in the slots. Of course that was on sale too which is why I tried it. Instead of really fixing problems or avoiding them they tend to just drop prices and sell more of it. We also just went through the whole different slower nand on the same part fiasco.

    Ah, ok. As someone looking into buying a new SSD soon, I sure would like to see how the 128GB version pairs up vs other SSDs in the same range. Hopefully you will extend the review at some point if you get different models :P
  • DigitalFreak - Wednesday, November 23, 2011 - link

    I wonder about that also. Seems like all the review sites got the 512GB model.

    hum, still seem to like the vertex 3 better. This could be good, but the other day newegg had a nice sale for the vertex 3 120gb max iops for 150. Really cannot beat that. I think the key though is benchmarks are getting overrated because these drives are so fast especially compared to hard drives. They need to have a reliability chart, that would be lol. I know I went through 4 vertex 1 drives before ocz upgraded me to vertex 2 so I am somewhat hesitant.

    Given that the vast majority of people (according to top sellers at NewEgg) buy drives in the 60 to 128 GB range, it seems odd that they're rarely represented in benchmarks. It'd be interesting to know what percentage of their sales are 512GB drives.
