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.
At a glance
| Product | Listed price | Form and scale | Notable hardware |
|---|---|---|---|
| QNAP TS-809 Pro | USD 297.49 | 8-bay desktop external HDD | 128GB SSD installed in bay 1 |
| LaCie 2big NAS | USD 300.00 | 2-bay NAS | 4TB capacity and silver finish |
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

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 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.
