TrueNAS Hardware

I run TrueNAS for network-attached storage. There are a number of sources for hardware recommendations: the offical guide, the community guide and the quick guide, among others. In addition, iXsystems makes its own line of TrueNAS Mini systems (see below). I modelled my own build after the TrueNAS Mini X as shown in the table below. Prices shown are those totals I paid locally in late 2020 before taxes.

Component	Selection	Notes	Price
Case & PSU	Supermicro SuperChassis 721TQ-250B	CS-M55 not available for retail purchase	CAD 242.05
Motherboard & CPU	Supermicro A2SDi-4C-HLN4F	includes Intel Atom C3558	CAD 412.00
ECC RAM	2 x Hynix HMA81GU7CJR8N-VK	2 x 8GB, per tested memory list	CAD 144.20
SATA DOM	Supermicro SSD-DM032-SMCMVN1	32GB, per tested HDD / SDD list	CAD 85.49
HDDs	2 x Seagate 4TB IronWolf	configured in a ZFS mirror	CAD 289.98
TOTAL			CAD 1,173.72

The NAS is protected by an APC Back-UPS Pro 1500.

Hardware Detective: TrueNAS Mini

Based on the teardown found in the Level1Techs forums, the TrueNAS Mini line appears to be based on Ablecom / Supermicro equipment, specifically:

Model	Case	Motherboard	CPU
Mini E	Ablecom CS-M50	Supermicro A2SDi-2C-HLN4F	Intel Atom C3338
Mini X	Ablecom CS-M55	Supermicro A2SDi-4C-HLN4F	Intel Atom C3558
Mini X+	Ablecom CS-M55	Supermicro A2SDi-H-TF*	Intel Atom C3758
Mini XL+	Ablecom CS-T80	Supermicro A2SDi-H-TF*	Intel Atom C3758

* The Mini X+ and XL+ use an active cooler on the CPU. The 10GbE board is a Chelsio T520-SO-CR.

Supermicro sells the Ablecom CS-M50 with the FSP250-50LC power supply as the SuperChassis 721TQ-250B (now with a 350W power supply as the 721TQ-350B). As mentioned on the Level1Techs forums, the SATA DOM and RAM are likely to change according to availability. TrueNAS Minis come standard with Western Digital Red Plus drives.
