Weird problem with X-25m G2

Does anyone know why my 4k read/write is so much slower than other people with the same drive??? Its a brand new X-25m G2 drive.

 

 

I even used HHDErase 3.3 to secure erase the drive when i first benchmarked it. I thought something was wrong with it. But even after a second secure erase, i am still having the same problem.

I have attached two different benchmarks. Everything is normal for the SEQUENTIAL read/write and RANDOM 512K Read/Write

 

 

Problem is with my 4K scores. It seems as tho they are cut in half than what they are supposed to be. AHCI is enabled.

^^^^^^^^^blowd

uuhhhh, you being sarcastic?

If youre not, youre wrong. G2 benches better speeds overall especially 4K writes.

Re: Weird problem with X-25m G2

Sorry bunta, this is what all of the articles about x25m Postville explain.

Also if you use google to search for specific benchmarks for the ssd you will see the same results everywhere.

and so on .....

 

Or read here : http://www.anandtech.com/cpuchipsets/showdoc.aspx?i=3607&p=4

In this article they've used a 160GB drive which does a bit better in the 4k.

So, where did you get your information from?

Re: Weird problem with X-25m G2

Im not understanding what you are saying... All the benchmarks you have posted have better 4K writes than i do. Yes, i do have a 80gb drive, but that doesnt mean, my 4K write should be 35%-45% less than others. Like for instance, the last benchmark you posted (the CrystalDisk has over 60mb/s in 4K write, and i have arund 30mb/s)

Can you please explain what you were trying to say? Im not quite understanding you. Is this from a desktop or laptop?

You're saying my drive is slower than others right?

Re: Weird problem with X-25m G2

I'm not saying that your drive is slower. Your 4k benches seems normal. But I see the difference in 4k write.

What Chipset you are using? (ICH9, 10, NV ??) Is AHCI in BIOS enabled and enhanced write and write caching in the Device Manager?

These settings will speed up your drive.

Re: Weird problem with X-25m G2

I have ICH9m/E . AHCI is enabled in BIOS. Write Caching is enabled under the drive's "policies". Where do i find "enhanced write" ???

Re: Weird problem with X-25m G2

Well, if you have the Matrix Storage Manager installed too, there is also one option to enable writeback caching.

And from the device manager there are these two options under the devices tap:

Hope that helps.

Re: Weird problem with X-25m G2

I dont have the options in Intel Matrix Storage Console. I dont have RAID setup. I have both options checked under Drive Policies in Device Manager. I have since found several other people with the same problem. All of them are laptops and they are saying its probably due to "mobile chipsets".. Im not sure i should believe it, but at this point, there really isnt anything else i can do but believe what they are saying.

Re: Weird problem with X-25m G2

For a Laptop I think it is a pretty good prformance. All the screenshots I posted are taken from Desktops. However, I have something in my mind that some energy saving option may slow down the SSD.

Im not 100% sure but I think this was written in a Toms Hardware Guide article.

Re: Weird problem with X-25m G2

I have the exact same problem, and it's really annoying to see that my 80go postville has is main advantage over OCZ vertex (4k writes) divided by 2.

Would be nice to have an other explanation that "you ve got a laptop, it's ok", yes i've got a laptop, but it has Intel proc / Intel chipset / Intel ..., so it would be quite annoying if you couldn't answer us.

Thx to people who will help especially if their' not paid to do it.

Re: Weird problem with X-25m G2

I do have same problem as well. I do expect something better from this drive, aspecially on Intel platform as Aznox stated.

Re: Weird problem with X-25m G2

Bunta,

Did you benchmark this from a laptop or desktop - if from a laptop your sata port's bandwidth is 1.5 Gb/s - newer generation desktop boards have sata 3 Gb/s - if you indeed did that benchmark from your laptop I would say amazing result.

Re: Weird problem with X-25m G2

I knew about the 1.5 gb/s vs 3.0 Gb/s issues before i purchased the Intel SSD. I verified i have 3.0 GB/s. And this is indeed on a laptop.

Re: Weird problem with X-25m G2

Aznx, Bunta, the performances of laptops are always not good as from desktops, in general. You should take the chipset, cpu generation, cpu speed, memory, FSB etc into consideration! My specs are P45 ICH10 355MHz FSB , 4 Gb Mem, Q9550 @ ~3Ghz. I would be disappointed if your laptop would be faster than my desktop. Again, compare with other Hardware which run on the same spec as you have and you'll notice that you could be happy with the performance. One thing I think of, is the fact that laptops are more designed for power saving and not for performance. Except .... maybe Alienware.

Sorry, for not being able to give you a better explanation. I never had a laptop, so I can only trust on what Im reading about.

RolandSSD:

Do you have your SSDs in Raid0? What chipset are u using? Have you had any issues with the setup yet? Since when u have the Raid running?

I was very happy with mit SSD Raid0 before I expierenced serious problems. The speed ... really was amazing, but one drive just disconnected suddenly, and no one has an idea why. Its RMA now. I really hope that this was really a drive failure and not an incompatibility with my P45-ICH10.

Re: Weird problem with X-25m G2

Bunta,

I totally agree with blowd, it's only normal that a high end system will perform better. Like I mentioned before I believe your results are outstanding for a laptop. Do a benchmark with Sandra and look at your random performance, i'm sure you will be pleased.

Re: Weird problem with X-25m G2

Blowd,

Don't want to hijack this post – I'm running in raid 0 for quite awhile never had a problem, also P45-ICH10R.

If you give the exact specs of your system and the way you had setup the raid maybe I can help you.

Re: Weird problem with X-25m G2

A lot of interesting data, but nothing that looks highly unordinary - other than I see very high sequential performance of >500MB/s read and >160MB/s write in earlier post that I'm not sure what that pertains to. These benchmark tests will vary across platforms and OS setups. Make sure to understand how the benchmark test is actually testing the SSD - what is the size of the test file it is working in and out of, does it test with queue depth, etc. As what's been alluded to by Roland, try another benchmark test to see if results are consistent. I recommend trying IOMeter. It is not as straight forward to use as some, but it has a lot of flexibility if one takes the time to learn it. If possible, test the SSD as a secondary drive. Also be careful what condition the drive is in - is it out-of-box, filled, etc - as that will affect scores. For more on this drive condition thing, check out Anand's SSD storage articles - his SSD Anthology or SSD Relapse - at http://www.anandtech.com/storage/ http://www.anandtech.com/storage/

Re: Weird problem with X-25m G2

It was around 20R/25W random 4k when out of box

of course that's not so bad, but i'd like to know why it's not better, because maybe it's just a software problem, maybe intel would just need to edit a line or two in his next chipset driver to get it fixed ...

Don't tell me it come from desktops being more "powerfull", i've seen many bench reaching the 60mo/s rand W. 4K with desk processors weaker than my T9300, and the uber GTX999 won't change anything to transfer rates.

I'm not crying that much, but i'm a bit disappointed because when i bough my ssd, it was intel 4K writes VS OCZ vertex general write speed ... and now i'm asking if i made the good choice ( something that never happened to me after buying Intel products before that :/ )

Again, i'm not blaming anyone, but i'd really like to know WHY it doesn't perform as expected.
