6 Things to Know About the TerraMaster F8-421 NAS

It uses the same Intel Celeron J3455 processor as the F4-421 and F5-422. This Apollo Lake quad-core chip is consistent across TerraMaster’s lineup from that era.

The F8-421 is an eight-bay NAS. It offers more drive slots than the four-bay F4-421 or five-bay F5-422.

The J3455 is a capable but older processor. It handles basic file serving and media streaming well, but lacks modern features like hardware transcoding for 4K video.

You should expect similar performance to the F4-421 and F5-422. Since the chip is identical, the main difference is storage capacity.

The F8-421 is best for users who need many drives in a single unit. If you don’t need eight bays, the smaller models save space and money.

TerraMaster standardized on this chip for a while. That means software and driver support is mature, but the hardware is not cutting-edge.
