Hi Fellas,

i bought one of the OCZ Vertex 2 50GB drives last friday to use in my PC as a boot disk for Windows 7 Ultimate 64 bit edition.

I tested the drives speed using ATTO and these are the results:

please take a look and see what you think? I used to be getting around 220MB sec read and roughly the same in write performance but for some reason or other i dont seem to be averaging even 200 in either and for what the drive should be capable of the write rate seems to be abysmal.

I have plugged the sata 2 drive into a sata 3 port and have tweaked windows a little. I've enabled AHCI mode, moved the page file, disabled system restore and a few other things designed to increase disk space rather than to improve performance. The only other puzzling thing is that now that i am in AHCI mode, i actually seem to have lost some performance, unless there are other settings that i have yet to modify i cant see how that should be possible?

please let me know what you guys think as i am sure that i can get more performance out of this drive than this.


Myth.

I think the problem is that the hard disk controller on the amd boards aren't as fast as the intel (ICH10R) controller. To get the full speed you may need an intel board or a separate raid card.
 
hmm, i guess thats worth looking into. The only problem with that is that i am crossing over to the I7 at the end of this month and it seems that it could be a bit of a waste of money, a good raid card would cost what? in the region of £200+. I mean don't get me wrong, one of these drives still out perform a lot of drives in a 2 disk raid 0 configuration, it would just be nice to be able to get the stated speeds.
 
is that through the motherboards standard sata controller or through an add in card? If it is through the motherboard itself, what board is it that you are running? im sorry but i looked purely at the benchmark results.
 
It's not a bad board, but there are certainly better boards out there.

I was looking at changing mine to either the Asus one you have linked to or the Gigabyte X58A-UD3 or maybe the UD5 but I still haven't decided yet ?

I never realised that there was such a difference between the two boards, it quite a negative for the AMD boards but they do cost quite a bit less than the Intel equivalents.
 
its becoming like a forest these days when choosing upgrades. There are that many things to choose from and different pathways to take that its starting to become difficult to make a good decision now. It occurs to me that we'll spend most of our time making trade offs with the hardware that we buy.

Like now, i don't know anymore wether to go for the I7 or go for one of the AMD hexa core processors. I like the look of the Asus Maximus Formual 4 but i don't know if there will be any performance increase over my Gigabyte UD5P.

every time one question gets answered now, a hundred more pop up. Choosing an upgrade path used to be so simple.

I've also partially fixed the issue with the Vertex 2 drive. It turns out, being the knob that i can be at times, that i was enabling AHCI on the sata 2 controller rather than the sata 3 controller that the drive is plugged into.
The only confusing issue now is that i am getting ove 260MB read speed but only 155MB write speed. I'm wondering if this is an issue with windows 7 and the sata 3 controller? but i don't know if i would be making the situation worse by installing windows vista 64 (i should imagine atto benchmarks would be the same) and plugging the drive into a sata 2 port (in which case it may also suffer).
