Same LinkStation, different capacity: which Buffalo NAS is the smarter buy?

Display

Neither product has a display in the usual sense, so there’s no screen quality difference to compare. On a NAS like the LinkStation 220, the real “interface” is the web admin panel and any status LEDs on the chassis. Because both products are the same Buffalo LinkStation 220 platform, this is a tie. For buyers, that means you should not expect a flashy front panel, touchscreen, or local readout on either model.

Performance

In day-to-day use, performance will be effectively the same because the hardware platform is the same and both are 2-bay LinkStation 220 units. The difference is not in CPU, RAM, or network capability, but in the amount of included storage: 4TB in Product A versus 8TB in Product B. That said, NAS performance is often limited by network speed and the modest hardware typical of entry-level home NAS devices, so neither model is the right choice for heavy Plex transcoding, multiple simultaneous users, or advanced Docker workloads. Winner: tie on raw performance, because the storage size does not change the underlying NAS speed.

Build quality and design

Again, this is essentially the same product line, so the chassis, bay layout, and overall design should be identical. Both are 2-bay NAS devices, which means the same practical form factor: compact, simple, and aimed at home users rather than enthusiasts who want hot-swap trays, NVMe cache, or expansion options. The 2-bay design is convenient for RAID 1 mirroring if you want redundancy, but it is also limited compared with 4-bay or 5-bay systems that offer more flexibility and better long-term scalability. Winner: tie, because the physical design is the same.

Battery life

There is no battery life to compare here. These are mains-powered network storage devices, not portable gadgets or laptops. If you were hoping for UPS-style backup, neither model includes that; you would need to add a separate uninterruptible power supply to protect against power cuts and avoid RAID or filesystem corruption. Winner: tie, because battery life is not a feature of either product.

Price and value for money

This is the only area where the decision becomes meaningful. Product A costs £308.00 for 4TB, which works out at about £77.00 per TB. Product B costs £462.84 for 8TB, which is about £57.86 per TB. On a pure cost-per-terabyte basis, Product B is better value, because you get double the capacity for less than double the price. However, Product A is £154.84 cheaper upfront, which is a significant saving if your storage needs are modest or you plan to use the NAS mainly for documents, photos, and light media backup. Winner: Product B for value per terabyte; Product A for lower initial outlay.

Game library/features

There is no game library on either device. If by “features” you mean NAS functionality, both are aimed at basic home storage: shared folders, file backup, and home cloud access. Neither is a feature-rich enthusiast NAS with advanced app support, ZFS, Docker, or VM hosting. For a Plex server, both are likely to be limited by the low-end hardware and are better suited to storing media than transcoding it. Winner: tie, because the software feature set is the same product family and neither is a high-end platform.

Overall user experience

For most home users, the experience will be nearly identical: connect it to your router, set up shares, and use it as central storage for PCs, phones, and media. The main difference is headroom. Product B gives you 8TB out of the box, which is much more comfortable if you’re backing up multiple devices, storing a growing photo library, or keeping a sizeable media collection on the NAS. Product A is easier to justify if you want a simple, lower-cost entry into NAS ownership and you know your storage needs are small. Because both are 2-bay units, neither gives you the flexibility of a larger chassis, but the extra capacity in Product B will delay the day you outgrow it. Winner: Product B, because it offers a better long-term user experience for most buyers who actually need a NAS.

Overall summary: these two Buffalo LinkStation 220 models are the same NAS in practice, with the same 2-bay design and the same user-facing strengths and limitations. The decision comes down to whether you value lower upfront cost or more storage and better cost per terabyte. If you want the cheapest way into a basic home NAS, Product A is fine. If you want the better long-term buy, Product B is the stronger choice because 8TB gives you much more breathing room for backups, media, and shared home storage.
