Crucial M4 128GB SSD Poor 4K read/writes with Sager NP8130

Here is the first AS-SSD test for my Crucial M4 128GB in my Sager NP8130 laptop:



I'm comparing the results in the AS-SSD benchmark thread in overclock.net (destop computers) but why is my "4K" speeds lower than normal? For other tests (seq, 4k-64Thrd, Acc.time) they seem to be on par with others. Is this because of the controller in the laptop? Here is a comparison of true average speeds of most people in the desktop world:

 

You answered it yourself: desktop platform vs. notebook.

Still very good 'score'.

 

Oh ok, no way to overcome this problem?

 

Best way is to test it against a HDD and compare scores. Then test them both in real life work. If you still have issues, come back. Only half kidding. You will notice a difference in what you do comparing your SSD vs anything non SSD. The difference in the benchmarks won't make a difference in what you see in real life. Don't let benchies worry you. I have done real life tests and the difference in real time work makes such a difference. Be happy and love it. As Tiller said, DT is different than LT.

There are some tweaks, but you don't need them. Just enjoy.

 

Hehe, I'm all for benches. I have an M4 with my desktop as well and I get higher scores. I do notice very much increased performance over a regular HDD but I need to see that the random 4K speeds are at par with the desktop counterpart. They are both Sandy Bridge chipsets anyway so they should have the same results or at least close to each other.

 

My Asus G73 had a built in throttle to the 4k writes on any ssd. There were workarounds, but there were limits as to what the 4k writes could do.

 

But I don't think our Sager systems have any built-in throttle, right?

 

There is probably no throttle at hand, it is more likely that windows are responsible. If you have them set on balanced mode or something like that, than they have slower reaction time to commands to preserve energy.

Check this thread on how to optimise cpu performance so that your ssd could run better. I got ~20% improvement in 4k and 512k write speeds over "high performance" profile for samsung 830 128gb. Read was already at it's max at about 24MBps.

Do note that we're talking about 4.2GHz i5 cpu in my desktop, that is way faster than anything you can possibly have in your notebook, therefore you should see improvements in all areas.

These modifications are battery eaters though, but considering you have sager, that probably doesn't mean much

 

Well, I'm on high performance right now. Why is the desktop counterpart, that is on high performance also, faster than the laptop AS-SSD benchmarks? Is it because of how strong the CPUs between both are?

Also, what is the difference between the thread you linked above and this: http://forum.notebookreview.com/sol...-series-4-5-965-chipsets-stamatisx-tweak.html ??

Yeah, no worries with the battery although I want it optimised as well, of course.

 

Try Use throttlestop and some SSD power plan twist

http://forum.notebookreview.com/sol...-intel-series-4-5-965-chipsets-jjb-tweak.html

and disable C1E in throttlestop see if it can help !
your CPU do take alot of affect on the SSD's speed too. (and alittle from the RAM)

see the attachments
my 4.5 month old SSD

 

So disabling C1E in the registry alone can remedy my problems?

 

try those SSD tweak first then disable the C1E (in throttlestop! google it) and OC your BCLK if possible
it worked for me ! goodluck

 

How can I disable C1E without the setting being present in the BIOS? With Throttlestop? I thought software solutions aren't so preferred?

 

The difference is cpu clock, faster cpu clock, faster response times. I doubt it matters how many cores are present. However, I have never gone that far to test that.

I'm not really sure what this tweak does, what those numbers mean, therefore I have never tried it, but seems to me that it changes how windows handle C states of your cpu.

Thread I linked tweaks specifically when and how windows manage cpu power saving features. When they boost clock to default speed and when they downclock it again. Test different settings if you wish to see the effects.

There should not be very noticable impact on battery, i'd say < 10%, but I haven't tried that on any notebook.

Also, throttlestop should be able to modify c states. I like having them On though, it saves lot of energy even if I can't overclock my cpu as much as i could, but 5% performance means little to me when power consumption is much higher and I have my pc on 24/7.

Try testing all things listed by others and me to see what gives you best results, and please report back your findings.
