QNAP TS-809 Pro vs LaCie 2big NAS: Which Setup Fits You?

Compare the QNAP TS-809 Pro and LaCie 2big NAS by bay layout, connectivity, capacity, and setup considerations, then choose the better fit for expansion or everyday file and media storage.

Last updated Aug 24, 2026

When shopping for NAS storage & drives, the central choice is whether you want a chassis that leaves room for a multi-drive plan or a more defined package for everyday files and media. The QNAP TS-809 Pro and LaCie 2big NAS are close enough in listed price that the hardware shape and intended workflow matter more than a small dollar difference. A practical way to decide is to match each enclosure's role to your network, computer mix, and plans for expansion.

Quick verdict

Choose the QNAP TS-809 Pro when its iSCSI target server role and expansion-oriented design fit your plan. Choose the LaCie 2big NAS when Mac and PC compatibility is central to the way you handle files. The listed prices differ by $2.51, so the price spread is unlikely to settle the choice on its own.

Where each product wins

QNAP TS-809 Pro: This is the clearer fit for shoppers prioritizing a larger desktop enclosure: eight bays are explicitly part of the configuration, making its expansion angle easy to understand. The product name also identifies an iSCSI target server, giving buyers with that specific network-storage use case a concrete reason to choose QNAP.

LaCie 2big NAS: LaCie fits shoppers whose setup centers on named connectivity. USB 3.0 is included in the product name, while Ethernet is identified for its network connection. Mac and PC compatibility adds a direct computer-fit signal. Choose it when those connections and computer platforms match how files and media will be handled.

Product notes

QNAP TS-809 Pro

QNAP TS-809 Pro Turbo NAS and an iSCSI target server 8 bay Tower Core 2 Duo 2.8

The QNAP TS-809 Pro makes sense for a shopper who wants a multi-bay desktop NAS with an installed 128GB SSD in bay 1. That included drive gives the configuration a concrete starting point, and the firmware is updated. The QNAP name also calls out its Turbo NAS designation, reinforcing the network-storage purpose. The important limitation is practical: it does not include a power cord, with a standard desktop-PC-type cord specified. Its condition is used, so favor it when the included SSD and desktop NAS format outweigh the extra power-cord step.

LaCie 2big NAS

LaCie 4TB 2big NAS Server; USB 3.0

LaCie 2big NAS is a sensible fit for an individual or small business organizing files and media around a 4TB capacity. Its silver finish is identified, and the two-bay enclosure gives the package a clear, compact scale. That defined configuration is the main reason to choose it when a contained NAS setup matches the job. The limitation is the two-bay count itself: shoppers planning a larger multi-drive arrangement should treat that as a constraint. The unit is marked used, so it suits a buyer comparing hardware configuration and capacity rather than specifically seeking a new device.

Final choice by use case

For an expansion-led home NAS plan, choose QNAP TS-809 Pro. For individual or small-business file and media storage, choose LaCie 2big NAS. If neither use case dominates, compare the connection needs first, then use the $2.51 spread as the tie-breaker.
