How to Choose Your NAS: 4TB LinkStation, 80TB 2-Bay, Iron Cow Enclosure, or Synology 5-Bay?

Compare four network storage options from a ready-to-run 4TB LinkStation to a build-your-own Iron Cow enclosure, plus an 80TB-capable 2-bay NAS and a used Synology 5-bay unit, and find the right fit for your files.

Last updated Aug 17, 2026

Choosing network storage usually comes down to a trade-off: do you want a ready-to-run system or an enclosure you can build around? These four options cover that spectrum, from a ready-to-run LinkStation to a build-it-yourself Iron Cow enclosure.

Quick Take

Buy the LinkStation 720 if you want a ready-to-run NAS with a closed security setup. Choose the Adventurous NAS if you want very large capacity. Pick the Iron Cow Zero 1 if you already own drives and prefer a bare enclosure. Look at the Synology DiskStation DS1511+ if having many drive bays matters more than buying a new unit.

Product Notes

Secure 4TB LinkStation 720 NAS

Go with this one when you want storage without assembly. The 4TB capacity is built in, and the title calls out MacOS 26 compatibility, so it fits an Apple-centric setup. It also uses a closed system designed to reduce exposure to third-party applications and includes SSL encryption, which makes it attractive if you prefer a more locked-down, appliance-style NAS. The tradeoff is that same closed approach: you give up the kind of third-party app flexibility you might get from a more open NAS, so think of it as a storage appliance rather than a mini server.

Adventurous 2-Bay NAS

This unit aims for scale. The title points to 80TB of potential storage and an Intel N100 processor, while the feature set includes a user-friendly app, an AI-powered photo album that recognizes faces and scenes, and a secure private cloud. It is designed to work with desktops, laptops, smartphones, tablets, and televisions, so it fits a multi-device home. The limitation here is the listed data transfer rate of 334 Megabits Per Second, which is modest for the price. If you copy very large files often, you may notice slower transfers than a faster network port would deliver.

IRON COW ZERO 1 Network Storage System

This is the build-your-own path. It is a 2-bay enclosure rather than a filled storage system, so you will need drives before it can hold anything. The 2.5GbE LAN port supports faster network transfers than a standard 1GbE port, and the RK3568 quad-core processor is aimed at handling audio, video, and general NAS work. The strongest reason to consider it is the low listed price, which leaves room in your budget for the drives you pick. Remember to factor in those drives when you compare it against systems that arrive with storage already included.

NICE Synology DiskStation DS1511+

For a used NAS with five bays, this Synology unit gives you room to grow. It supports HDDs and is described with a hybrid HDD/SSD format, and the interface list includes USB 3.0, M.2, NVMe, eSATA, USB, and Gigabit Ethernet. That variety of connections makes it flexible for a home office or small creative setup. Since it is a used unit, the main limitation is that you are buying a pre-owned piece of hardware rather than a new system. The five bays are the strongest reason to pick it if your storage plan calls for more drives in one box.
