Introduction
The Asustor Drivestor 4 Gen 2 AS1204T is a compact 4-bay network attached storage solution designed for users who want centralized storage, home cloud access, backups, and media management without moving into the complexity or cost of a larger business NAS. It features a quad-core 1.7GHz processor, 1GB DDR4 memory, a 2.5GbE network port, and three USB 3.0 ports, while the diskless design lets you choose the drives that best match your storage requirements.
Although the supplied keyword is Smart 12 bay NAS storage system Kit, this particular model is a 4-bay NAS rather than a 12-bay system. That distinction matters when planning capacity. Its four drive bays are better suited to home users, creators, small offices, and families who need centralized files without requiring a large rack-mounted storage platform. With the right drives and RAID configuration, it can become a practical hub for documents, photographs, videos, backups, and other important data.
The 2.5GbE connection is one of the most interesting hardware features because it provides more network bandwidth than traditional 1GbE NAS connections when the rest of the network supports multi-gigabit Ethernet. That can make transferring large files and working with shared media libraries feel more responsive.
Features
The AS1204T Gen 2 focuses on useful hardware rather than unnecessary complexity. Its four drive bays provide several options for configuring storage, while the diskless format allows buyers to select compatible hard drives or SSDs based on capacity, workload, and budget.
Four-Bay Storage Architecture
Four drive bays give this NAS considerably more flexibility than a two-bay enclosure. Depending on the selected RAID configuration, users can prioritize usable capacity, redundancy, or a balance between the two. For a home cloud environment, four bays also provide a practical path for expanding storage over time as a media library, photo collection, or backup archive grows.
The diskless approach is especially useful for experienced NAS buyers because you are not locked into a preconfigured drive package. You can select storage devices appropriate for your workload and replace or expand them according to the supported configuration and NAS requirements.
Quad-Core 1.7GHz Processor
The quad-core 1.7GHz CPU provides the processing foundation for everyday NAS tasks such as file sharing, backups, storage management, and supported applications. A NAS does not need to behave like a desktop PC for these workloads; instead, consistent background operation and efficient handling of network requests are key considerations.
For typical home and small-office duties, the processor is designed around the practical needs of a network storage appliance. Users should nevertheless distinguish between ordinary NAS workloads and demanding server applications or intensive transcoding tasks. Hardware requirements increase significantly when many simultaneous users or computationally heavy applications are involved.
2.5GbE Networking
The integrated 2.5GbE port is a major feature for anyone upgrading beyond conventional gigabit networking. To take advantage of the higher network interface speed, your computer, switch, router, cabling, and network configuration must also support the relevant multi-gigabit speeds.
When those conditions are met, large file transfers can benefit from the additional network bandwidth. This is particularly relevant for photographers, video enthusiasts, and small offices that frequently move large folders between computers and shared storage.
1GB DDR4 Memory
The NAS includes 1GB of DDR4 memory. This is appropriate to keep the appliance focused on core storage functions, but buyers should understand that memory capacity is one of the hardware limitations compared with larger NAS platforms. If your intended workload involves numerous demanding applications, virtual machines, containers, or extensive multitasking, a higher-memory NAS platform may be more appropriate.
For centralized file storage, routine backups, personal cloud functions, and ordinary media organization, the hardware configuration is aimed at a more straightforward NAS experience.
Three USB 3.0 Ports
Three USB 3.0 ports add useful flexibility for external storage and compatible peripherals. They can be valuable when moving data between external devices and the NAS or when connecting supported USB accessories.
This is a practical feature for home users because NAS storage does not always exist in isolation. Many households already have external drives containing photographs, documents, or other files, and USB connectivity can simplify certain data-transfer workflows.
Home Cloud and Backup Potential
One of the biggest reasons to choose a NAS is the ability to bring multiple devices into a centralized storage environment. Instead of maintaining separate copies of family photographs, work documents, and media on several computers, a NAS can act as a shared destination on the local network.
For small offices, this can also create a central location for files and backups. The exact backup features and supported applications depend on the installed NAS software and current compatibility, so users should check the manufacturer’s current documentation before designing a critical backup strategy.
4K Media Center Use
The Drivestor line is also designed with home multimedia use in mind. A centralized NAS can organize movies, photographs, music, and personal video files so compatible devices can access the library across the network.
However, media playback and transcoding are different concepts. Direct playback of compatible media files generally places different demands on a NAS than converting video into another format in real time. Users with demanding transcoding requirements should verify the exact application, codec, resolution, and client-device requirements before purchasing.

Performance
In everyday use, the AS1204T Gen 2 is best understood as a centralized storage appliance rather than a desktop replacement. Its performance profile makes sense for file sharing, backups, personal cloud access, and media organization. The quad-core processor provides the computing foundation, while the 2.5GbE connection gives the system an important networking advantage over many older 1GbE NAS designs.
Network performance deserves particular attention. A 2.5GbE interface does not automatically mean every transfer will operate at 2.5Gbps. Storage-drive performance, RAID configuration, computer hardware, switch capabilities, cabling, protocol overhead, file size, and simultaneous users can all affect real-world throughput. A compatible multi-gigabit network is therefore an important part of the equation.
For large file transfers, the additional network bandwidth can be particularly useful. A photographer moving RAW image libraries, a content creator organizing project files, or a small business copying large archives can benefit from reducing network bottlenecks compared with older gigabit-only setups.
Storage configuration also influences the experience. With four bays, users can select an appropriate RAID arrangement according to their priorities. Redundancy can help protect against individual drive failure, while a larger-capacity configuration can emphasize usable storage. Before setting up the NAS, it is worth deciding what data is genuinely important and where an independent backup will reside.
Home Office Experience
For a small office, centralized storage can simplify everyday file management. Instead of passing documents between individual computers or relying entirely on removable drives, team members can work from a shared network location where appropriate. The NAS can also serve as a dedicated backup destination for supported computers and devices.
For home users, the appeal is even broader. A single NAS can become a central location for family photos, personal documents, downloaded media, and device backups. Its four-bay architecture provides substantially more flexibility than a single external hard drive because users can design the storage around their redundancy and capacity requirements.
Media and Entertainment
A NAS-based media library can make it easier to keep personal content organized. Instead of maintaining multiple disconnected libraries, users can place supported media files on centralized storage and access them from compatible devices on the network.
Before relying on the NAS for a particular 4K workflow, check the playback device and application requirements. A client capable of directly playing the original file may require much less processing from the NAS than a client that needs real-time transcoding.
Is It Really a Smart 12 Bay NAS Storage System?
The keyword Smart 12 bay NAS storage system Kit describes a much larger class of storage hardware than this product. The AS1204T Gen 2 itself has four drive bays, not twelve. That makes it important to match expectations to the actual specification.
A 12-bay system is generally aimed at substantially larger storage pools, more drives, and often heavier business or professional workloads. The four-bay architecture here is more compact and can be a better fit for users who do not need twelve physical drive slots. If your storage requirements are moderate, four bays can offer a useful balance between expansion potential, redundancy options, and physical size.
Who Should Consider the AS1204T Gen 2?
This NAS makes the most sense for users who want to move beyond standalone external drives and build a centralized storage environment. Home users can use it for personal cloud and media organization, while small offices can use it as a shared storage and backup destination.
It is also worth considering for users who already have a 2.5GbE network or are planning to upgrade their network infrastructure. The faster Ethernet interface provides more headroom than a traditional gigabit connection, particularly when moving larger files.
On the other hand, users planning to run numerous demanding server applications, virtual machines, containers, or computationally intensive media workloads should carefully compare the CPU and memory requirements of those applications with this NAS’s hardware.
Setup and Storage Planning
Because this is a diskless NAS, the initial setup begins with selecting compatible storage drives. Think about capacity, drive type, expected workload, redundancy, and backup requirements before installing them. A four-bay enclosure gives you multiple configuration possibilities, but the right choice depends on the data you intend to store.
After installing the drives, connect the NAS to the network and configure the storage environment through the supported management software. It is also a good time to establish user accounts, shared folders, permissions, backup schedules, and remote-access settings where appropriate.
Security should be part of the initial configuration rather than an afterthought. Use strong unique credentials, keep supported software updated, restrict unnecessary network exposure, and maintain independent backups of irreplaceable information.
