I'm having some trouble with 2x Seagate IronWolf 10TB disks in a simple RAID0 aka "Stripe" configuration using Windows Storage Spaces on Windows Server 2016 v1709. This server is being used for Plex and torrents. Nothing fancy, but it seems like the RAID-array is not up to the task. Having a 540/540mbit Internet connection I'm having issues with the torrent-client not being able to write fast enough to the disk so the result is disk overloaded messages. The downloads max out at about 68MB/s so I have a hard time understanding why this is such a big problem at times. Even a single disk should be able to handle that load, so having two in RAID0 shouldn't really have any issues? It seems like the issue occurs more often when there are multiple downloads going at the same time, so its obviously not enjoying having multiple writes going at the same time without dropping performance. Is this to be expected? Due to limited amount of RAM and how the torrent-client tends to crash when you start playing around with caching it seems like letting the client itself handling caching of disk writes is a no-go. But I suppose Storage Spaces itself should be doing some kind of write caching by itself, or no? I could of course double the amount of RAM on the server and dedicate a few gigabytes for disk caching but I don't really know how to manage disk caching of storage spaces? I can't seem to locate any options for it. All I can seem to find is options for adding SSD-cache to RAID5/6.
