why not to use os raid 0 option ?
softraid is an app that also requires some attention from machine.
i would go with systems raid 0
my first question was if your drives are suspended in 2 hours maybe ?
res pinning will always make machine lag.
also all not needed software would affect performance.
I would turn off power option what suspends drives.
also try os version of raid 0 (backup first)
