This thing is a beast. The OS is smooth, there’s a ton of plugins and apps, it’s like a server of its own. Data transfers are quick and painless. The ram in it is impressive as well. 8 Gigs of ram in a NAS. For those hardcore streamers out there, it can transcode 4k on the fly. Scalable up to 9 bays, supports 2 pcie SSD drives. Definitely, the way to go for performance. Highly recommend.
