"Very fast!"5.0 starson by fed250
Pros: Fast, DSM has tons of options. It is almost as powerful as a server. Best nas on the market. Expandable for growth.
Cons: A little expensive but there was just a recent price drop. No usb 3.0 why??
Summary: Great unit for home or business! Not sure why others had so much trouble I have never had an issue at all with Synology products. Has an easy setup wizard process for non techies but if you are a techy there is so much you can unlock with this thing. Hoping they add thunderbolt for next year!
