Just throwing hardware or new collectors at it may be more trouble than it is worth.
If you have determined that your disks are the bottleneck, you next need to determine what process is hogging the disks. You can use something like iotop for this. http://guichaz.free.fr/iotop/ Once you've determined what process is hogging all the disk, you can than look at the type of data it is reading/writing. Is the data valuable? If not, put it on tmpfs. Is it hogging the disk based on throughput, seek times or latency? Then you can optimize a storage solution based upon the characteristics of your data. Your solution might be as simple as adjusting some caching parameters, but you won't know until you know why exactly the disks are being slammed.
