8 Best Enterprise NAS Devices for 2023

Enterprise Network Attached Storage (NAS) devices are centralized file servers well-suited to business use. Affordable and easy to manage, they provide a wide range of data storage needs and are one of the easiest ways for businesses to set up or expand a data storage network.

They can be configured to provide backup and recovery of on- and off-site mobile devices and computers. They can also host applications, develop web and server-side applications, and perform big data analytics operations. And Enterprise NAS solutions start at around $1,000, making them affordable for most midsize and small business needs. As a comparison, a Storage Area Network (SAN) solution starts around $10,000.

When choosing a NAS solution for your business, pricing is just one of the factors to consider. It’s also important to consider the number of concurrent users in the organization, the maximum storage capacity necessary, scalability for future growth, and advanced encryption options for security.

Here are our top eight picks for Network Attached Storage devices for the year as well as a comparison chart comparing features and prices.

Key Features of NAS Devices

NAS devices are ideal for small to midsize businesses because they can fit within a company’s budget. Besides price consideration, there are some key features you want to consider before making a purchase:

Data Security

Business and customer data will be stored on a NAS device that can now be accessed from a business Wi-Fi or cable connected network or possibly remotely through the internet. System administrators can change default ports and enable security options like SSL, firewalls, and two-factor authentication to help protect data. However, for businesses that must protect proprietary data or customers’ data,advanced security options like AES-256 encryption is a requirement.

Seamless integration with other NAS devices

When a NAS device is reaching maximum storage, some NAS devices are able to seamlessly integrate with the current NAS devices online.  Synology NAS devices are designed with a plug and play feature to accomplish the integration through its Synology DiskStation Manager that does not require any device to come offline.

Redundant Array Independent Disks (RAID) technology

Most NAS devices use RAID technology to protect data in case of a hard drive failure. There are different RAID levels to use in NAS devices, but the recommended RAID level to use is RAID 5 because it can withstand two concurrent hard drives failing without losing any data.

Backup Operations

Backup operations are a common function in NAS devices.  There are some NAS devices that can automatically synchronize backup operations with enhanced backup features like QNAP’s  hybrid backup sync feature that automatically backs up QNAP NAS devices or other storage solutions, which requires no manual intervention once configured.

Concurrent Users

Whatever NAS device you decide to buy, you need to make sure it can meet the demands of the number of users that concurrently use the NAS device.. Knowing the maximum number of users that can connect and use the device without degradation of performance is important to know.  Additionally, knowing the limitations of your Wi-Fi or cable-connected network is a factor that will influence the performance of your NAS device when it’s reaching concurrent maximum capacity.

Bottom Line: Network Attached Storage Devices

Network Attached Storage devices are an affordable, easy way for businesses to set up or expand network data storage. Compared to general purpose servers, NAS devices are faster and offer easier administration for IT staff. Choosing the right one comes down to identifying needs and matching them to specific features.
