Efficiency: Performance Per Watt

Hot or Not? New Samsung and Solidata SSDs
By

Although the new Samsung 256 GB SSD cannot beat the throughput we’ve seen from Intel’s X25-E drive, it requires less power to deliver almost the same transfer rates. This means that it gets very close with regards to efficiency, which we define in total read I/O operations for the benchmark run per watt. Solidata spoils its results due to the high power consumption of its X1 and X2 drives.

If we switch to workstation-type I/O activity, the efficiency measurements are different. The X25-E drive by Intel is so much superior to the other drives, as it delivers much more I/O performance at low power consumption levels.

    Can we have the drop down list of pages back?
    I really don't want to go through every single page to get to the results and conclusions.

    Also note that on the graphs the Intel x25-M is labeled as 64GB, where on pg 8 it says it comes as 80 or 160.. Also did the x25-M have the new firmware?

    The 256Gb Samsung is available for general sale in the UK; I bought one last week.

    I just wish new Table of Contents (TOC), or drop down was on every page, after I get past page 1, you either have to go back to page 1 to jump ahead/around or page though

    Considering that the Samsung PB22-J is a MLC-based drive like Intel's X25-M, Samsung beats the crap out of Intel with write speeds.

    Also, Register Hardware reviewed the same drive six weeks ago!

    We used to get 3 and 4 new articles a day.Now it's been reduced to one.
    I would think with all new teck in the market place we can find more than just hard drives to talk about.
    As I mentioned before there are a new host of monitors out there.One that do 120htz and the response times have gotten better.It would seem the 24 inch monitors have been catching up to the smaller 22 inch counter parts in terms of speed.
    This is the would be article you won't get for a long time I am afraid.

    What I also find odd is that there are more ads on Toms than before but they get rid of our avatars?I have to wonder why?

    Thank You for making the "Table of contents" actually accessible!!!

    Place the table of contents in every page, not just the first. And put it at the bottom of the page, so you can use it after you read the page. Currently you read the page and have to scroll up to use it.

    This article avoids detailed discussion of the controllers used in the SSDs, does not emphasize the importance of small random write tests, and implies that OCZ does not have a product, when in reality the OCZ Vertex using the Indilinx controller has the second best performance to Intel at half the price. The JMicron controller is garbage. Read the vastly superior articles on AnandTech "The SSD Update" and "The SSD Anthology" for more information.

    Perhaps this is an irrelevant question, and you'll understand why in a moment, but would owning an SSD with a throughput of over 200 mb/s help in situations where the amount of available ram is exceeded? IE - in games where instead of writing to RAM, the program would have to write to the HD as virtual ram. Oftentimes I would notice a stuttering when a new area in a game was streamed from the HD when I didn't have available ram, would this effect be eliminated? (The reason I felt it was somewhat irrelevant would be because those of us who can afford to buy a $400-600 SSD drive can probably afford a few more gigs of ram - or would have the ram in the first place.)

    Drop down list again please, forcing me to see all of your ads by removing drop downs, or having a dozen image pages instead of text only forces me to add more things to adblock.
