this is the first time i have used a ssd much and its performance has droped of a fair bit

it had been running for a month with windows 7 on it as a ide drive

the ssd is on the sataIII ports which are set to ahci

now i have reinstalled windows to another drive deleted the partitions and done a quick format on the ssd before coppying ~60g of games back to it

looks like its allined so what have i missed?

I just installed an OCZ Vertex 2 SSD.

 

Took out previous normal hard drive.

 

Enabled AHCI in bios.

 

Then plugged in SSD.

 

Then went and installed windows.

 

Everything is zippy.

 

Did you change to AHCI after already installing the drive?

 

Note the thread on this forum about the new Vertex 2 and their reduced performance. Do you have one of those?

ahci was enabled before the new windows install which is not on the ssd this time it just has games now

aparently running these benchmarks can can reduces ssd performance\life a fair bit from what i have read on the ocz website so maybe its just that combined with removing the previos windows install and running it half full that is makeing it slower than normal and if thats the case its rather disapointing

 

its still faster than the old wd black 1tb but nothing mind blowing

boot times were nice for quickly testing overclocks

but i cant say im that impressed

the performance im getting from it at the moment isnt far from the a-ram 30g indilinx i put in a atom about a year ago

 

unless they are releasing some of the slower drives with 111.79g im fairly sure i have a fast one

 

 

edit

here is the 30g indilinx drive it has faster read speeds but much slower write

read speed is what realy interests me and the fact that this vertex 2 is getting beaten by that...

have you run trim on it?

how? i havent been able to find anything about it so asumed windows 7 did it automatically assuming it detects it as a ssd which it seems to have as its not set to be defraged

Windows 7 is supposed to take care of it, yes. However, I've heard various stories about this not always being the case.

 

They are unconfirmed however.

 

I'd suggest downloading a copy, running it and redoing your tests.

looks like trim is running

 

did a secure erase on the drive this helped a little

also re updated the bios since it had reset to the default and set both controlers to ahci unlike previously i only had the sata3 controler set to ahci and now performance has improved a lot

Sorry Dasa, what do you mean by 'both controllers'?

p67a-ud4 has intel sataII and sataIII ports each can be set to ide or ahci

i have the 1tb os drive and the ssd on the two sataIII ports set to ahci

a 2tb hdd and optical drive are on the sataII ports which were set to ide (couldnt boot from optic with it on ahci) but now set to ahci and from what i can tell this was the problem although i dont know why it would be a problem

Which SATA port do you have your ssd connected to?

the white plugs closest to the cpu going by the manual they are sataIII as i said above

try plugging the SSD on a SATAII port instead of SATAIII.

 

I have mine on a SATAII and my WD Black FAEX on a SATAIII

Thanks for the clarification.

 

I'm going to have to have a close look at my setup now :)
