Synology to TrueNAS Migration

Project Overview

Migrating from an underpowered Synology DS124 (1GB RAM, no transcoding) to a custom-built TrueNAS server with an Intel i5-12500, 32GB RAM, and 2x8TB mirrored drives. This upgrade enables hardware-accelerated 4K Plex transcoding, expandable storage up to 48TB+, and secure remote access through Tailscale.

Hardware Specifications

CPU Intel Core i5-12500 (6P cores, 12 threads, 3.0-4.6GHz)
iGPU Intel UHD Graphics 770 (Quick Sync for transcoding)
Motherboard ASRock B760M Pro RS (mATX, 6x SATA)
RAM Corsair Vengeance RBG 32GB DDR5-5600 (2x16GB)
Storage 2x Seagate IronWolf 8TB NAS (Mirrored ZFS Pool)
Boot Drive Kingston NV3 1TB NVMe M.2
PSU Corsair CX550 80+ Bronze 550W (Semi-modular)
CPU Cooler Thermalright Assassin X120 Tower Cooler
Case Fractal Design Define 7 (6x 3.5" bays, sound-dampened)
