Storage Capacity and Memory Comparison
Drive Bays
The Asustor Lockerstor 4-Bay Quad-Core NAS provides four drive slots for your data. This model is diskless, meaning you must purchase drives separately. The Asustor Lockerstor 6-Bay NAS includes six drive bays, offering more physical space for expansion. It comes bundled with three 1TB SSDs, giving you immediate storage upon setup. If you need room for a growing media library or large dataset, the six-bay unit offers two additional slots. The four-bay model is better if you prefer a smaller footprint and plan to use fewer drives.
RAM Capacity
Memory is crucial for handling multiple tasks and virtual machines. The Asustor Lockerstor 4-Bay Quad-Core NAS ships with 4GB of DDR4 RAM. This is sufficient for basic file serving and light media streaming. The Asustor Lockerstor 6-Bay NAS doubles this with 8GB of DDR4-2933 RAM. The higher capacity and faster speed allow for smoother operation when running multiple containers or heavy database queries. If you plan to run many apps simultaneously, the extra memory in the six-bay model prevents bottlenecks. The four-bay model may require upgrades for heavier workloads.
M.2 NVMe Slots
Cache and speed benefits come from NVMe SSDs. The Asustor Lockerstor 4-Bay Quad-Core NAS includes two M.2 NVMe slots. This allows you to add fast storage for caching or a dedicated pool. The Asustor Lockerstor 6-Bay NAS offers four M.2 NVMe slots. This flexibility lets you build a larger cache or a high-speed tiered storage system. If you rely on SSDs for performance acceleration, the six-bay model provides double the expansion options. The four-bay model is adequate for basic caching needs but limits future scaling compared to its larger sibling.
Included Storage
Setup convenience varies between the two models. The Asustor Lockerstor 4-Bay Quad-Core NAS is sold diskless. You must buy hard drives or SSDs separately before you can use it. The Asustor Lockerstor 6-Bay NAS comes with three 1TB SSDs included in the box. This bundle provides immediate functionality without extra purchases. You get 3TB of fast storage right away. If you want a ready-to-use solution without hunting for drives, the six-bay model is more convenient. The four-bay model requires additional budget for storage components.
Form Factor
Physical dimensions affect where you can place the device. The Asustor Lockerstor 4-Bay Quad-Core NAS measures 6.69 inches wide, 7.3 inches high, and 9.06 inches long. It weighs 6.53 pounds. The Asustor Lockerstor 6-Bay NAS is significantly larger at 12 inches wide, 13 inches high, and 13 inches long. It weighs 14.9 pounds. The four-bay model fits easily on a desk or in a standard rack. The six-bay model requires more space and may need a dedicated shelf. Choose the four-bay model if space is limited in your home or office.
Which Asustor NAS Should You Choose
Users needing immediate storage capacity
This model includes three 1TB SSDs for a total of 3TB. You get six drive bays for future expansion. The 8GB DDR4-2933 RAM offers higher bandwidth. Four M.2 NVMe slots allow for fast cache. This bundle saves you from buying drives separately.
