Not the best solution for storagenode. It will have a concurrent requests for storage with other stuff.
I expect that your node would have a lot of canceled requests because it will loose the race for pieces to other nodes with more fast storage.
You can use this script to have an idea:
Also, keep in mind - the NFS and SMB are not supported, your node will have problems with the storage sooner or later. The smallest from the problems is broken or unavailable databases (empty dashboard as result).
