Drobo B810n 8-bay NAS (DR-B810N-5A21): Overview

Release date and price

Drobo launched this desktop NAS on the 25th of October 2015. The development of this 8-bay small business NAS provided Drobo with the opportunity to introduce new features alongside the ease of use that Drobo has built its reputation on. 

Drobo NAS is generally cost-effective, and the B810n delivers value for money because the manufacturer has included some of its best features, like fast self-healing, Data-Aware Tiering, and Data Aware Caching.

Different Models

A more recent but related model is the Drobo 8D DAS (released in November 2018). This 8-bay device is direct attached storage (DAS), rather than a NAS, and requires a direct connection to the device accessing data from it. The specifications of these two storage solutions are very similar, but the 8D does not have the remote access, updates, and file-sharing capabilities of the B810n NAS. 

Please note: As of July 17, 2023, Amazon lists this item as being out of stock. If you’re unable to obtain it elsewhere, please check back with Amazon at a later date.

So what makes this 8-bay NAS a bestseller? Here are the notable features of the Drobo B810n 8-bay NAS:

1. Easy setup and low maintenance

Drobo has put in the hard work so you can have a hassle-free experience with this performance NAS. There is almost no setup and few ongoing maintenance needs. All you need to do to get this NAS up and running is:

  • Install Drobo Dashboard on your hardware,
  • Insert the SSD and hard disk drives you require,
  • Connect your network cables,
  • Switch on the NAS,
  • Set your administrator username and password. 

Yes, it really is that simple!

2. Data-Aware Tiering and Data Aware Caching 

The Drobo B810n 8-bay NAS benefits from some great technologies taken from other NAS models. This NAS uses the Data Aware Tiering that was first introduced in the 12-bay Drobo B1200i.

This feature automatically detects and configures SSDs that are added to the NAS, creating a new tier that accelerates the NAS performance. In addition, Data-Aware Caching automatically speeds up the reads of your most commonly accessed data. 

3. Dual Gigabit Ethernet ports

The B810n carries twin gigabit Ethernet ports you can use individually to connect to different subnetworks or bond for doubled read/ write performance. The paired ports can also function in active/ passive mode, meaning that one port can take over from the other if it fails. 

4. Enterprise-level disaster recovery

The Drobo B810n secures your data with its integrated disaster recovery solution, DroboDR. It not only backs up your data but also the settings and configuration of NAS and the user account. This means that in the event of a power outage or drive failure, you can recover and run a saved replica of your original B810n.

5. myDrobo 

You can securely access data held on your Drobo via a secure end-to-end connection using the myDrobo feature. As an administrator for this NAS, you’ll receive a mydrobo.com address for public Internet access and use of Drobo’s suite of practical applications known as DroboApps.

You can use these apps to remotely manage WordPress files, upload media from remote devices, and use the services of third-party vendors like ElephantDrive or Resilio Sync & Plex for additional backups, syncing, and data protection. 

6. LDAP compatible

The Drobo B810n is also compatible with the Lightweight Directory Access Protocol (LDAP). This is a mature and widely adopted and supported standard for directory servers. You can set up an active directory with LDAP to use the NAS for applications like user authentication. Simply update the firmware via the DroboDashboard. 

7. Smart power solutions that protect your data

Drobo protects every device from data loss and corruption by adding an in-built battery that has adequate power to back up the data in memory or cache. The integrated battery continually keeps itself topped up so that your NAS stays protected.

Drobo B810n 8-bay NAS (DR-B810N-5A21): Review

The B810n is a reliable NAS that is built for the NAS novice. Its strengths are its simplicity and ease of use rather than performance and technical specifications. This simple NAS is also fast, so it should satisfy most small business users.

However, businesses that are growing fast or have greater technical requirements are likely to want to move on from this NAS quickly as it does little more than store your data.

Excellent build quality

Drobo has not skimped on the quality of this NAS. It has a robust metal chassis with a magnetically attached front cover. A removable cover hides the drive bays and has windows through which you can check the amount of free space that is available, as well as the status LEDs.

Adding storage is simplified by the removal of the drive sled – just slide the hard disk drives directly into the bays. Installing 2.5-inch drives is a little more challenging but everything is 100% tool free. 

Could do with more ports

The chassis and cover are vented to keep things cool and the entire unit sits on 4 rubberized feet. This maximizes the cooling from the paired fans in this NAS. At the back, there are two ports for Gigabit Ethernet and an AC power socket. Though these ports offer fast connectivity, it would have been great if there were other types of ports, like USB, available for data transfer. 

Intuitive software interface 

Drobo has designed the DroboDashboard with a novice user in mind. It looks like the home screen of an iPhone, a design feature that is likely to be deliberate. For a performance user, this interface is likely to be a little thin as it only has a few pages and it actively minimizes user interaction.

Most operations are one-click, like switching from single- to double-disk redundancy. You can also use the dashboard to map the folders to your local PC rather than building the shares in Windows. 

DroboApps is the best software feature and has the potential to extend the longevity of this NAS by providing software solutions from third-party developers. At the time of writing, Drobo has 47 apps, which is less than its competitors, but as the range of apps grows, so does the utility of this NAS.  

Help is not always at hand 

Despite having in-built help and support links in its Dashboard software, some Drobo B810n customers have struggled to get timely help with problems. This matters because the warranty for this NAS is unusually short, at only one year. It is worth extending the warranty with a DroboCare package, but be prepared to pay several hundred dollars for the privilege!


Not only is the B810n not a cheap NAS, but it also lacks several performance and software features that customers would expect at this price point. However, this NAS is not targeting the sophisticated NAS user, so this stripped-back approach is likely to prove lucrative for Drobo.

Drobo B810n 8-bay NAS (DR-B810N-5A21): Pros and Cons


  • Quick and easy assembly that’s 100% tool-free.
  • Hard disk drives just slip in.
  • Can accommodate SSD drives.
  • Easy setup and integration into an existing network.
  • Hardware is easy to handle.
  • Strong metal chassis with detachable magnet front panel. 
  • Easy-to-use dashboard and app-based interface.
  • Some enterprise-level features like SSD cache and DroboDR.


  • This is a predominantly SATA-based NAS which is slower than flash-based memory.
  • Despite being high-capacity, this system is not very sophisticated. 
  • Too few ports limit options and convenience for data transfer.
  • Multiple reviewers of this NAS have often found it hard to get customer support.
  • Low RAM and CPU spec for the storage capacity of the NAS.
  • The hard drive is embedded and cannot be upgraded.
  • Cannot upgrade the hard drive
  • The one-year warranty is extremely short. 

Drobo B810n 8-bay NAS (DR-B810N-5A21): Is It a Buy?

This is a high-capacity NAS that is easy to install, set up, and run. Drobo has done the hard stuff for you with DroboDR and smart power solutions. However, for the capacity, this Drobo NAS is a little light in the technology department as there isn’t a serious attempt at robust volume management. 

Buy it if…

You are new to the NAS market, or you’re a photographer or creative who needs a mature storage option for backing up your work. You’ll be able to access your data quickly and add media from your camera or other devices using myDrobo. Small business and enterprise users are likely to outgrow this 8-bay NAS, though it provides a great user-friendly introduction to working with external storage. 

Don’t buy it if…

You are an SME that is looking to scale its storage. Drobo’s prosumer focus means that its simplicity may chafe if you require more technical management of your business data. 

Final thoughts

This respectable build from Drobo is a great package for NAS newbies and the DroboApps provide some room for growth. But if you’re a NAS expert, this NAS is going to be too simple and unable to perform the acrobatics a pro expects!

Drobo B810n 8-bay NAS (DR-B810N-5A21): Review and Best Deals FAQs (Frequently Asked Questions) 

Does the Drobo B810n 8-bay NAS (DR-B810N-5A21) NAS have BeyondRAID®?

BeyondRAID® is a RAID-like technology. Like Redundant Array of Inexpensive Disks (RAID), it undertakes data storage virtualization and volume management on the NAS, and has added features that include:

  • Thin Provisioning/ thin storage / virtual provisioning: the allocation of on-demand storage according to user needs. 
  • Instant Expansion: automatic mobilization and reorganization of unused storage space.
  • Inclusion of mixed drive sizes in a single pool that is then reorganized and configured virtually.
  • Smart Volumes® that use the capacity as needed as volumes taken from a common pool.

What is Ethernet?

Ethernet is a wired networking technology that is standardized by the Institute of Electrical and Electronic Engineers (IEEE) as standard 803.2. It uses twisted pair networking cables to create network connections. Ethernet is part of the physical layer (PHY) in the OSI 7-layer model of computer networking and can be used for:

  • Data transfer,
  • Telecommunications,
  • Audiovisual applications,
  • Internet connectivity.

In addition, Ethernet uses Cat 5e, Cat 6 or Cat 6E cable to provide high data throughput and speeds.

Is SATA better than SSD?

Serial Advanced Technology Attachment  (SATA) and Solid State Drives (SSDs) are two different storage technologies with marked differences in their underlying mechanisms and speed.

SATA is an older technology that uses mechanical hard drives that require data to be physically written on a spinning disk. The mechanical operation of this non-volatile storage makes it significantly slower than Solid State Drives (SSDs).

SSDs store data in electrical circuits rather than writing it on a disk. This makes them extremely fast; at least three times as fast as a SATA drive. However, SATA hard drives remain popular because of their large capacity and lower cost. 

What is a Rackmount NAS?

A rackmount NAS is a NAS with a form factor that makes it suitable for mounting on a vertical rack that has industry-standardized dimensions. These NAS are larger than the personal ‘desktop’ NAS and have the bays arranged in racks with a specific unit of height. The unit (U) represents the rack unit of height which is usually 1.75-inches (44.45mm). 

Is the Drobo B810n 8-bay NAS (DR-B810N-5A21) loud?

The noise level of a NAS can make or break your relationship with it. Thankfully, the B810n is whisper-quiet with the acoustics for normal operation at only 30.4 dB. The main source of noise is the paired fans that cool the NAS.

What is LDAP?

Lightweight directory access protocol (LDAP) is an open-source, vendor-neutral protocol that is used to access and maintain static data like: 

  • Usernames,
  • Email addresses,
  • Passwords,
  • Printer ID,
  • User authentication.

LDAP records static, descriptive, and valuable data using specific syntax that helps users pull the information they need quickly. Users interact with the data stored with LDAP frequently.
