Choosing NAS storage & drives is a trade-off between enclosure capacity, what arrives in the package, and how much you want to spend before adding storage. The QNAP TS-809 Pro and Qnap TS-431P2 point in different directions: one emphasizes a larger bay layout, while the other presents a lower-cost NAS enclosure. The right pick depends on whether you want the broader listed format or a leaner starting purchase.
Quick verdict
The QNAP TS-809 Pro is the clearer fit if the 8-bay layout justifies the higher initial outlay. The Qnap TS-431P2 is the clearer fit if the 4-bay NAS format and lower listed price align with your plan. The absolute price spread is $127.54. The choice is therefore between a fuller starting configuration and a lower-priced enclosure-first route.

Where each product wins
Where QNAP TS-809 Pro wins
- Starting configuration: The description names an installed 128GB SSD in bay 1 and updated firmware, concrete reasons to favor it when you want storage already present and firmware already updated.
- Named server role: The title includes *iSCSI target server*, so this is the natural match when that specific role is central to the plan.
Where Qnap TS-431P2 wins
- Lower listed price: At USD 169.95 versus USD 297.49, it is the lower-priced route, with a $127.54 spread to the TS-809 Pro. This directly suits shoppers setting a firm initial budget.
- Included caddies: Four caddies are included, which makes its package detail more relevant when you already have drives to install.
Product notes
QNAP TS-809 Pro Turbo NAS
With the title's *iSCSI target server* wording, the TS-809 Pro gives a concrete reason to choose it for a setup built around that role. The description also says the firmware is updated, a useful listed configuration detail alongside the installed 128GB SSD in bay 1. Its limitation is the missing power cord; the described requirement is a standard desktop PC type, so a separate cord is part of setup. The unit is marked used, making it the higher-initial-cost path here. Choose it when the named server role or included drive matters; leave it aside if supplying a power cord and paying more do not fit the plan.
Qnap TS-431P2 Network Attached Storage NAS
Qnap TS-431P2 is framed in the title as a Network Attached Storage NAS and Personal Cloud, a concrete reason to choose it when that enclosure role matches your plan. The package limitation is equally concrete: it is described as having no drives and no power adapter, so both pieces must be supplied separately. The unit is marked used. That makes it an enclosure-first purchase rather than a ready-with-drive starting point. Choose it when you are comfortable assembling the storage around your own drives and adapter; leave it aside if an included drive is important. The lower listed price keeps its trade-off clear without changing the practical setup requirements.
Final choice by use case
- Choose QNAP TS-809 Pro when the named iSCSI target server role or an included starting drive matters. Its listed configuration gives that path more setup detail to weigh.
- Choose Qnap TS-431P2 when the lower listed price is the deciding factor and you are prepared to supply drives and a power adapter. Its Personal Cloud wording and included caddies support that enclosure-first use case.
The short version: QNAP TS-809 Pro puts the emphasis on a more defined starting configuration, while Qnap TS-431P2 puts the emphasis on a lower entry point. Match the package contents and listed format to the work you expect the NAS to do, rather than choosing by model name alone.
