What to Look For in a best 2 bay nas?

The best 2 bay nas is a product type that many customers feel hesitant to select because of the challenges in evaluating its features. It comes to trust! When studying a significant purchase, many factors must be considered. Our best 2 bay nas knowledge will help you make an ideal decision.

Our article here will highlight some outstanding items and provide solutions to FAQs and guides to buying. You should keep in mind some main criteria of best 2 bay nas below:

Ease Of Use

A NAS is a great option for small businesses that need a solution that can run without much maintenance. Choosing a NAS that can be set up quickly with minimal labor is always a wise decision. For enterprise solutions, higher labor and administrative costs are insignificant when compared with the benefits that a NAS can bring.


RAID stands for redundant array of inexpensive disks. RAID can be quite complex but at a basic level, you’ll want to use it to provide redundancy so if a disk fails your data is still safe. Three of the most popular variants are RAID 1, 5, and 6.
Whatever RAID you choose, however, don’t consider your NAS to be the only backup of your data. If the box just dies, or if something catastrophic happens like a fire, you’ll still lose all your data. To mitigate this you'll want another external backup, preferably to the cloud.


In simple terms, the more drives you can cram into a NAS the greater its potential storage capacity. In most cases, we suggest something with four or five bays like the Synonology DS-1511. Loaded up with a swag of 1TB or 2TB drives it offers plenty of capacity.
If your needs are more modest then a two-bay unit is also handy and won't break the bank.

Form Factor

The form factor of a computing device affects the design of hardware components that go into the larger unit. For NAS storage devices, form factor usually comes in two variations: rack-mount, and tower type cases. Choosing between these two options is straightforward. For example, rack cases would be suitable for enterprise networks since they have an expandable capacity. Tower type casing is better for consumers or small-to-medium businesses.


What type of processor does your NAS need? NAS drives run dedicated OSes that require a lightweight processor and more RAM. A faster processor and more memory will enable features such as transcoding, which means that any media files can be converted on the fly into a format that's playable by your TV or set-top box. It can also be useful if your videos are a higher resolution than your TV can handle, so look out for the ability to transcode 4K to Full HD in real-time.


After storage, the next main concern is software and features. We prefer NASes that have an app store where you can download popular apps such as Plex instead of forcing you to use the manufacturer's own media software. NASes also offer apps for Android and iOS, which make it easier to get to your photos, videos, and music from your phone or tablet.

Ports And Connections

Don't overlook connectivity. If your priority is to use your NAS as a home video server, it might be worth picking one with an HDMI output like the QNAP TS-251B so you can connect it directly to your TV. And if your TV can't play video from a network source, you'll need a separate media streamer.


What is a 2-bay NAS?

A two-bay Network Attached Storage (NAS) is a device that offers data storage and digital media streaming capabilities, typically over a local area network or the internet. It usually consists of two storage drives, allowing for faster data transfers, redundancy, and backup options for multiple users.

What are the benefits of a 2-bay NAS?

The main benefit of a 2-bay NAS is its ability to provide fast, secure storage for multiple users. It also offers backup and redundancy options, allowing for a backup of all data stored on the device. Additionally, a 2-bay NAS can also be used to stream digital media content to multiple devices, such as Smart TVs, computers, and mobile devices.

How do I set up a 2-bay NAS?

To set up a 2-bay NAS, you will need to connect it to your home network and configure the NAS settings. This can be done through the web-based management portal or the manufacturer’s software. Once your NAS is connected and configured, you can add storage drives, create users and manage access permissions.

What type of drives can I use with a 2-bay NAS?

The type of drive you can use with a 2-bay NAS will depend on your specific NAS model. Generally, 2-bay NAS devices support traditional spinning hard drives and solid-state drives. You can also use RAID (Redundant Array of Independent Disks) to create a mirrored drive configuration, which provides redundancy and better performance.
