OCZ Agility 3 raid 0

[thodoris125]

Hi.I bought 2 x OCZ Agility 3 SSD 120GB and I want to make them operate in raid 0. The mobo is Asus Rampage Formula III. I read that they work better on the ICH10R controller than the Marvell controller so I connect them on the ICH10R in raid 0 with stripe size 128K. Because i have no idea, what speeds playing around on these ssds in raid 0? Somewhere I saw about 900 ~ 1000 MB/s in Atto Disk Benchmark. I need to make some settings from Windows 7 or the Rapid Storage Technology?

Thank you in advance.

Im sorry, what are you asking? Have you run ATTO to see what speeds you are getting? I would just set the stripe size and go (though unless you frequently manipulate large files, I wouldnt go R0).

Here are the speeds benchmarks...Are they good?

Looks like you have maxed out the controller... Thats why your curve is so flat.

Are these results good?

Put the RAID on the SATA III ports.

For those drives they are not. Unless you use SATA III ports you will not achieve anything near 1TB per second.

Sata 3 ports are on the Marvell 9128 controller which has problems with raids...What can i do?

Oh you have no intel SATA III ports That stinks. Well that is about the best you can do with 2x raid 0 on SATA II

WAIT you should have 2x Intel SATA III ports.

EDIT. My bad no iSATA III.

Do you suggest me a sata 3 controller for my mobo so i can reach 1TB/s?

None that are affordable. To me when you move to a card you need Intel or better and for the money it is really not worth it on an x58 board. You can get a cheap controller but you get what you pay for.

Now I would really break that raid and go single drives.

Yeah not much is gained there.

 

[thodoris125]

With single drives i will have speeds ~200 MB/s which is the half from the speed of the raid!

Well you should have closer to 300 than 200. Shoot my SATA II Raid 5 is is as fast as your SSD and that is 1.5GB.

If you are only doing 200 you have some other issue.

Exactly.. should be hitting about 28xish on SataII.
