Image Hosting

[Indo Php]

hi there,

we have an image hosting, and of course we're using Nginx!

Now on we're having problem with disk i/o. With 200GB of images.
Is there any recommendation for this matter? Nginx configuration or 
Hardware/other software configuration?

We already used Dual Quad Core 3Ghz, 8 GB RAM, 6x73GB 15k SCSI server
