Readynas 104 drops out when copying to it

Hi, I've been having the same problem. The NAS works fine to a certain capacity, then after that point it starts hanging whenever I try to copy files to the NAS. All the snapshots have been turned off, antivirus is off, it's RAID-0 with two drives installed. The NAS will hang, and the network drives to it will become unavailable. After about 10 minutes, I'll be able to access them again. Each time I've contacted netgear support they've said the problem will be released in the next patch. After 6.1.5 it worked for a week or two, but now it's hanging everytime. It looks like people are still having this problem, but are netgear going to do anything to fix it? What's the point in buying hardware like this, when it can only be used to 70-80% of it's capacity? Perhaps we should all get a 30% refund on the cost of the unit and the drives that are being used by it.
