I posted a few days over on the Synology forum, but only 31 views and no help so I thought I'd try my luck with my favorite internet community. I know a lot of Mac user lean toward synology solutions, so here goes nothing! As a new Synology owner I'm still learning my way around. I have 2x 2TB drives (new) and an older 500GB drive in SHR. All was well with the volume (still shows status normal on all drives) and I copied 1TB of data over a couple days (not constant copying) at over 30MB/s. Now I've been trying to transfer a 5GB file and my speeds zip up and down from 200KB/s to 1.3MB/s and average around 900KB/s. My Synology CPU is low, ram is at 40%, so I can't figure out what happened. We did have a power outage that shut everything down, and I didn't run the Synology for a couple days after this, but now it's back on and the transfer speeds are very slow. Running gigE directly connected through my Apple Airport Extreme - same setup that gave me vastly higher speeds before. Input appreciated.
