Power Consumption

The Vertex 4, similar to the Octane before it, consumes entirely too much power at idle. OCZ tells us that this is a known issue, also fixed in the next version of the firmware that should reduce bring it down to roughly 0.75W at idle. At ~1.3W today, the Vertex 4 would draw more power than many 5400RPM 2.5-inch hard drives at idle - something to keep in mind if you're planning on putting this thing into a notebook.

Drive Power Consumption - Idle

Under load however, the Vertex 4 does quite well. It's more power efficient than Samsung's SSD 830, while offering similar if not better write performance. If your aim is better battery life and not performance however, you may want to stick with one of the 3Gbps Intel drives instead.

    "monitoring port of the SSD"
    Please enlighten me, Google was no help...
    Is it a hardware interface that allows you to see how the drive operates?

    Basically, every SSD has some sort of real-time data port that allows engineers to monitor what is going on with the SSD, even when the drive hangs or has other issues. It is used mainly for development/testing. Consider it sorta like a way to read/access the dump file when Windows BSOD's, except in this case it's on the SSD. This monitoring port gets disabled on released drive firmware and the hardware attachment leads are unattached.. Reply

    Thanks for asking this! I always wanted to know that myself. I actually google it to no avail while I was reading the article. Reply

    How long till we are overclocking our SSD processors :-/ Reply

    Umm. How you gonna fit that water cooler inside the case? Reply

    hahaha... NEVER!! I've yet to break a Win7 installation from overclocking, but I broke XP many times... I shudder at the thought of overclocking an SSD :) Reply

    Although, I wonder how long until the processors in SSDs reach, say, today's single-core Atom... OR better yet, how long before the SSD controller is built into the CPU much like the memory controller, where we install more storage the same way we install ram... and then later again the nand controller and RAM controller merge, and a computer is nothing more than a SoC with some nand sitting next to it...

    We finally have controller that are able to bump out MB faster then Sandforce without using some silly compression engine. Marvell also announced next Gen SSD controller as well.

    Again we have reached the limit of SATA 6Gbps, we will need to start thinking about SATA Express, Lower power consumption, reliability. etc...

    Though I think the high consumption might be because of the controller, the chip is huge! With thermy sticky!

    Wonder when a die shrink of this is possible.
