I currently have a DS1019+ with 5x14TB drives. I just upgraded from 5x10TB drives that I would like to also utilize as I'm now full. I would also like to upgrade to a larger/faster NAS and don't know if that means I need 10Gbe, SSD cache, more RAM, etc. Ideally I would like to utilize the 10 drives I currently have. I would also like 10Gbe speeds for large file transfers from my main PC as I deal mainly in large movie files. I don't know if its just a network speed issue or what, but currently if I try to do any maintenance such as deleting files or copying files around while Handbrake is running an encode, which is almost always, the whole network comes to a halt until the bandwidth is freed up again. What would you suggest as the best upgrade for both size and the speed I need to be able to multitask? The NAS is used as an Emby server so some transcoding is required, but I typically preencode all of the files that are shared to limit that. I would prefer to have a single NAS as opposed to expansion units or a 2nd NAS, but I will make that concession if it makes the most sense.
