got it all up and running now with a fresh install of Win764 bit.

HDD performance with windows drivers on the Windows experiance index is 7.2 so far.

there are a few issues with one partition on my normal hdd not showing up anymore tho.

knighty

how fast does it feel ?

Im guessing itll speed up a lot once you get it all setup right etc...?

no idea where it is, but have you set the option to tell windows youre running SSDs ?

Im getting 6.4 for the hard drive score on mine, but I get the impression anyone can get a 5, a 6 is harder, and a 7 is really good ?

DEViANCE

I havent got enough time to play fully atm but here are couple of sandra benchmarks.

it does feel alot faster, apps just load straight away no lag at all.

Ive never had too much faith in hard drive benchmarks....

according to that, your drives are being beaten for access time by a traditional hard drive !

DEViANCE

the top one is my old traditional hdd :)

edit:
here is the bar graph for the new drives.

Can you do a hdtach short bench? Im wondering if its worth going to ssd from this -

I know sh*ts bad right now with all that starving bullsh*t and the dust storms and we are running out of french fries and burrito coverings.

DEViANCE

just done it and it is pretty much the same average read and slightly lower burst speed, so it looks like Ive still got some tweaking to do.

DEViANCE

somthing is not quite right here, according to loads of online reviews of these drives I should be getting about double the speed Im acually getting.

DEViANCE

I dont know what is going on!

I formatted and started again and still got the same results, and then started experiencing random restarts and one of the drives kept disappearing from the raid on POST.
So I though it must be a faulty drive.

but I have connected them into my mobo so they are running individually (not raid) and they seem fine and very very fast.



any ideas?

crappy maplin raid card being sh*t?

Why not pop over to the OCZ forums & see if you can get any ideas.
My Vertex 2 has a similar graph in HDtach to yours but burst is a lot higher(245 to 260).
Atto harddrive benchmark seems to give realiable results.http://www.techpowerup.com/downloads/1749/ATTO_Disk_Benchmark_v2.46.html
Mine scores about 250 m/s for both read & write , could optimise for more but it is fast enough as it is :)
Have u tried AHCI mode ? might be the difference

ive been tawling loads of foums inc ocz for ages and nothing seems to match my prob, ill have another play tomorrow and failing that I start a thread on ocz

Once youre happy let us know what you think as I am thinking of a single SSD for windows 7 and Eclipse. Eclipse is a Java IDE that generates 2 billion tiny tiny temp files an thus I think would benefit from solid state.

knighty

a tenner says it is the crappy raid card :(

DEViANCE

anyone have any idea how to enable NCQ, apparently that might help me.

Clock'd 0Ne

NCQ should always be on as it is usually part of the controller for SATA, so unless youre using IDE mode in Windows instead of RAID/AHCI it should be working with it enabled I would have thought.
