RAID controller, as the name implies, is used for controlling a RAID array. It is the device for managing the physical disk drives for maintaining their functions. RAID controllers also work to control the disks in the RAID so that they work as the logical unit. A RAID controller works towards helping the device to act on RAID recovery.
Use either a food dehydrator or an oven, but not a microwave, to dry your mushrooms, as the latter does not offer enough airflow. Dehydrating, especially in a dehydrator that uses a consistent, low temperature, will not affect the nutritional quality of your morels.
Most morels in the market are burn morels, which mean that they grow in mass quantities in the burn zone areas of a forest fire the following spring after the summer fire has occurred. Morels are hollow and thus bulkier in volume, so more of them have to be collected to make a pound than solid wild mushrooms like chanterelles or porcinis.
