Looking for a home NAS for a couple TB of space (preferably with lots of redundancy). I'm definitely looking for 4+ HDD capacity. Partially for RAID 5 and more redundancy, also for more storage. Initially looking between the new Synology DS411+ and DS1511+, but a friend recommended QNAP, so I pulled up some random models around the same price (TS-509 PRO, TS-459, and TS-559 Pro+) - NewEgg Comparison Link Also glanced at the Synology DS411j and DS410, but I'm not sure if one's an older model, or what the j stands for. I like ReadyNAS products as well, but when they got bought out by Netgear the prices skyrocketed. Not cool. Features I'd like: to be able to add HDDs at will (hot swappable would be nice as well) Being able to host a web site (I think both Synology and QNAP do this) DLNA support Awesome that both Synology and QNAP products can provide storage for virtualization servers. That's really tempting, but I may or may not run VMs at home. It'd be nice, but I could always do that on local storage. In fact that may be preferred if I get some SSDs. Not deal breakers: bit torrent / NZB client built in (Synology only I believe) So, does anyone have a preference between the two or any experiences / reviews they'd like to share, or other make / models they'd recommend?
