 ## Multiple pools
 
-Unraid allows you to create and manage up to 35 separate storage pools, each with up to 200 devices. Multiple pools give you flexibility to allocate storage for different tasks, improve performance, and customize redundancy based on your needs. Each pool can use a different file system, %%RAID|raid%% level, and device type (SSD, HDD, NVMe, etc.).
