Read performance is less then write because of the used software RAID5.
Using JBOD configuration (4x separate disk), gives both read and write above 100MB/s
OpenMediaVault Forum for tips, tricks and specific questions:http://sourceforge.net/apps/phpbb/openmediavault/index.phpUsing Med500X / 400X2 / 500X2 to stream from it.
Setup als follow:
Using the My_Shortcuts method as shown in this demo
http://www.mede8er.com/Mede8er_X2_Add_Shortcut.htmlAlso using NFS streaming from 400X2 and 500X2 without issues.
