I was just saying it was unknown to me too.

Lol. But for other SSDs all of those SMART parameters are known? iS this something to worry about for the Plextor M3?

No idea from me.

I read at Google that the Marvel chip is the cause of these unknown attributes. Not sure if that's true?

Hey, this is my first post on overclock.net. I just got my 2nd Plextor PX-M3P and put them into RAID0. Performance is great! My speeds aren't quite as good as IM0001 but they are right up there. I'm using the onboard Intel z77 chipset RAID controller on my Gigabyte z77x-D3H. My first attempt was on the onboard Marvell controller and I can attest that the Marvell controller performs like crap. I got lower speeds in RAID0 than I did with only 1 SSD in AHCI.

@IM0001 What RAID controller are you using and what stripe size did you choose? I chose 128K and "write-back." Any recommendations? Does the fact that my OS is installed on the array affect test speeds?

I thought this was kinda cool so I'm including screenshots. Among the first few tests I ran, after installing windows, was an AVI encode with Convertxtodvd. The FPS is well over 500 smile.gif . At the time of the screenshot my system was running on at OEM clock speeds for CPU and RAM.

So I just wanted to post screenshots illustrating the difference in benchmarks I get with C-States enabled and disabled. I mentioned in my earlier post that they are significant, at least for me, and affect pretty much every aspect of SSD performance (as measured by synthetic benchmarks).

First, my AS SSD results with C-States disabled:

513

AS SSD results with C-States enabled:

511

To me, these differences are just crazy, especially regarding 4K and access times. The access time for reads doubles!

Perhaps there is another thread that discusses this at length or there is a more appropriate section for this topic, but I was wondering if anyone would care to weigh in on this. Ideally I could leave C-States enabled, because I don't OC (gasp! sacrilege!), and I'd rather not have my CPU idling at a constant 36x multiplier (which is a weird multiplier to be stuck on anyways), but I just hate the thought of losing all that SSD performance, even if I might not be able to notice the difference under normal usage. In regards to 36x being an odd multiplier to be stuck on, I have an i5 3570K, so 34x is the normal load multiplier, and 38x is the maximum turbo multiplier. I guess it decided to go with a happy medium? Also, with C-States disabled, the multiplier won't increase beyond 36x either, so no true Turbo Mode for me.

So... Any thoughts on what to do? Or can someone point me to a thread that maybe has the information I seek?

Just leave them enabled imo. I don't notice a difference besides in benches. Actually if you put the CPU under some sort of load then the SSD will perform as if the power saving features were disabled when running the bench. Run AS SSD with say prime 95 or similar running 1 core or something.

I have a 5GHz OC with my i5 and have my C-States, C1E, and Intel speeds step enabled.If I didn't my room would be hot as hell. lol

Oh and someone made a bigger thread on it: http://www.overclock.net/t/1262255/effect-of-power-saving-features-on-ssd-speed

Interesting! Thanks for the reply.

I loaded up a core with Prime 95 like you suggested and sure enough, I'm getting performance more or less on par with C-States disabled. The read access times were still lagging a bit, but not as much.

On an unrelated note, I think I'm finally ready to try my hand at a little overclocking. Too bad Ivy Bridge isn't a great candidate for OC frown.gif

Forgot to mention this. I won a 128GB M3 from a contest Plextor had on Facebook a few months ago. I was stoked! Sold my Crucial Am very happy with this drive.

And they've released firmware version 1.05 btw.

Did you guys check the M5S reviews?

I can't see any improvements over M3S. What do you think?
