Hard Drive Raids obsolete for most projects?
The $/GB still favors spinning disks. My Synology 1821+ with 10GigE, NVME cache drives and 100TB of spinning disks still gets 1000MB/s read & write speeds so I can edit uncompressed 4K video.

Stick with 6×4TB SSDs or move to large HDDs for a Plex NAS?
SSDs are wasted on a NAS, don't bother. The bottleneck is your network connection. Its like taking a 5 gallon bucket and dumping it into a drinking straw.

Help power saving settings ASUS Pro WS W790-ACE (Xeon W3)
Pros and cons honestly. Either you keep it simple and within a budget or you toss the wallet at it like I did and end up with that "WANT" vs what you really "NEED". Assumed I was gonna be sitting at 20w idle, have VMs, AI with dGPU, a all in one solution to get rid of all other systems, and to repla
