PCMark 7 And Idle Power Consumption

OCZ Vertex 4 Review: A Flagship SSD Powered By...Indilinx?
By

With deadlines looming, we had to make some choices about the tests we ran. This time around, we dropped our in-house trace-based metric. Instead, we're using PCMark 7, which was written to perform a similar function.

Overall, the Vertex 4 doesn't beat the Vertex 3, but that's because the majority of PCMark 7's Storage Suite is compressible. This explains why the SandForce-based SSD 520s and Vertex 3s remain some of the fastest drives on the market.

OCZ's Vertex 4s deliver competitive performance just behind Samsung's 830.

Fact: Because SSDs are so fast, they sit idle most of the time. During our recent virus scan benchmark, which lasted almost 30 minutes, the SSD was only busy for 281 seconds. As a result, idle power consumption is the most important figure to consider in a desktop environment.

Samsung's 830 does exceptionally well here. Even though it employs a beefy triple-core ARM-based controller, it consumes slightly less power than Crucial's m4 and its dual-core ARM-based Marvell controller.

The Vertex 4s are the real power hogs; both models require more than 1.2 W. It's difficult to pinpoint the reason for this power result. In theory, the dual-core Everest 2 controller should require less power, but of course the drive's PCB design could contribute to higher consumption.

    Remind me why no over-provisioning is a good idea (other than increased capacity) - I wonder about the usable life of this product in a typical desktop or laptop system.

    Are Sandforce 2281 SSD's more reliable in terms of percentage of life?

    untill they make SSD's more reliable and able to do everything a normal hard drive does, they simply are not worth it..
    when the working life of a SSD is around 4-5 years, then ill buy one, but when they normaly slow down and suddenly fail after a few months... who would waste money on these? :/

    @ JakeyBoi - are you not over-reacting a little bit? My Vertex2 is 18 months old now and is heavily used aswell, didnt notice any slow-downs nor problems with it... Surely - it WILL degrade, I am aware of this, but "few months"? come on....
