SSD 830 speed

[czesiu]

Is this normal performance for a Samsung 128GB 830 series SSD as a system drive?
Writes seem to be slow (and always have been)

Post the rest of your system details, drivers used so we can put this in context

ASUS P8Z68-V/GEN3
i5 2500K
HD4850

What driver details would you like to know?

 

[Coup27]

Those numbers do seem low to me, I also have the same drive.

Was the drive clean before you installed? (ie new or secure erased)

Try running the Perforance Optimization within SSD Magician. This will force execute TRIM and GC which may help.

Also double check your partition alignment.

Chipset and RST driver numbers would also help.

drive was new
alignment is ok (105 906 176 / 4096 = 25 856)
After performance optimization sequential write is 220, but that seems to be within error margin
RST 10.6.0.1002
Where can I check chipset drivers version?

 

[Coup27]

Run Registry Editor (Start -> Run -> regedit -> enter)

Once in the Registry Editor expand "HKEY_LOCAL_MACHINE"
Next Expand "SOFTWARE"
Next Expand "INTEL"
Click on "Infinst"

On the right hand side there will be two things to look for.
First is to make sure the line that says "Install" has the word "success" next too it (to the right, under "data" ). This indicates the driver was installed correctly.
Next find the line that says "Version", and that will be your version number that was installed.


Also there is a newer RST, grab that from Intels website and install.

chipset @ 9.2.0.1021 ; RST @ 10.8.0.1003 ; ssd magician performance optimization once more and sequential write is ~230-240

chipset @ 9.2.0.1021 ; RST @ 10.8.0.1003 ; ssd magician performance optimization once more and sequential write is ~230-240

should I try 9.2.0.1030?

 

[Coup27]

You want to be running chipset 9.3.0.1019 and RST 10.8.0.1003. Can get both from Intels site.

I have the same drive and a similar Asus Z68 motherboard so our scores should be about the same. I can't post my CDM's right now as I'm on my mates PC which I'm repairing atm.

Aside from partition alignment, AHCI mode being on, using a decent SATA cable and the above drivers being installed then the scores should be there.

 

[czesiu]

with 9.3.0.1019 seq write is 250 in CDM

 

[Coup27]

We'll we're going in the right direction. Did you update RST as well?

If you give me a couple of hours to finish this PC, when I'm back on my rig I'll upload my CDM scores. As our systems are very similar it should provide you with a good comparison.

RST is updated.
We are not really making progress, CDM just shows slightly higher numbers (as-ssd just measured seq write 225)

Take your time, it took me weeks to post about this problem

 

[bryanW1995]

I don't see a comment about ahci. Are you running in ahci mode?

 

[Coup27]

I did mention AHCI to him but surely the QD=64 4k score would be a lot lower if AHCI wasn't on?

 

[czesiu]

AFAIK iaStor in AS SSD means AHCI is on

 

[Coup27]

Sorry czesiu it's taken me this long, I've only just got back on my own machine. Here are the only benchmarks I have for mine. I have never used AS-SSD.

 

[groberts101]

disabling c-states, speedstep, and making sure to set high-performance power scheme in W7's power mgmt should set you straight.

ram speeds will affect caching speeds and push numbers up as well.

 

[Coup27]

My RAM is 1333. No point getting anything faster on an i3.

maybe not.. but I was just pointing out that an identical machine with slightly faster ram will generally produce higher synthetic benchmarks, was all. Not too many benchmarks that don't show benefits from faster ram/caching these days.

PS. he spec's an I5 above. They do respond very well to faster ram.

 

[Coup27]

Our machines are very similar so I'm not sure why his drive is slower than mine. I'm pretty sure I haven't altered c-states or speedstep, not sure if they're on or not. Changing chipset and RST drivers helped so it might be how his system was setup to begin with. I'm a pro ()

Power scheme is high-performance

I don't think RAM can be a bottleneck for SSDs, yet

 

[Coup27]

C states obviously have an affect on performance. I will check mine next time I reboot.

All of your read scores are fine, but write scores are all lower.

Unless you are prepared to secure erase and start over I don't know what else to suggest..

secure erase... wouldn't that (potentially) work even if I just backup the whole partition, erase and restore?

 

[Coup27]

Yes it would, but with active TRIM and GC and you've also used the SSD Magician performance optimization feature, if you simply restore your current image onto the SSD it's likely not to change anything.

You were previous running old chipset and RST drivers so are you sure you have a nice clean install of Windows 7 with correct alignment, correct optimization features (superfetch, prefetch etc) and the latest drivers all round? Thats more what I was suggesting.

 

[Coup27]

I just checked mine and EIST is enabled. Also my C1E, C3 and C6 are all on auto.

Tbh I'm probably going to leave them that way. I rarely tax my machine to the full and more enjoy a generally fast and quiet machine, hence my decision to go with an i3-2130.
