I’m a photographer with about 5-6TB of data, currently stored across 4 4TB drives in an internal RAID5 setup. I use a Highpoint 2721 controller. I’m considering a Synology DS1515 NAS which supports multiple configurations. From what I’ve read, these devices use software RAID but do it using their own CPU and RAM. So there’s no additional overhead for my desktop hardware. My question is whether my drives will perform as well in the Synology NAS as they do internally? I’m planning to connect it to my desktop via eSATA. In this case, the Synology would function as my primary storage. I’d back up regularly to external hard drives via USB. If there’s going to be a performance hit, I’d consider buying a new set of drives and running the Synology as a constant backup with the additional function of making my files available to me when I travel.
Hope this makes sense and thanks for your help.
12/16/16 update: thanks for your answer, @kanewolf. I now realize that I can't have my cake and eat it. I don't want to give up the performance (roughly 400Mb/s) of my RAID, so I'm putting the server on hold. My best bet seems to be a Drobo 5Dt which has a TB2 interface. If I need to access my files remotely, I'll do so through my desktop.
