QNAP Systems has announced the availability TS-453Bmini, the company’s newest vertical NAS solution. Featuring a modern glossy build, the TS-453Bmini is equipped with the latest Intel 14nm J3455 quad-core 1.5GHz processor, AES-NI encryption, 4K UHD output and transcoding. QNAP calls their new NAS a high-performance NAS solution that provides users with security and intelligent services and designed as an ideal data storage, backup, sharing, and entertainment option for home and small office use.
With upwards of 8GB DDR3L dual-channel RAM, dual Gigabit LAN ports and SATA 6Gb/s, QNAP quotes the TS-453Bmini to reach read speeds of 225MB/s under AES-NI 256-bit hardware-accelerated encryption for both shared folders and the full NAS volume. The TS-453Bmini can also be expanded to 120TB via QNAP’s 8-bay UX-800P expansion unit; the device’s tool-less design also makes upgrades to the NAS itself (e.g. installing larger HDDS and more RAM) a seamless process.
The TS-453Bmini uses the latest version of QTS (4.3), which offers a plethora of updated and new applications designed to promote the efficiency of management tasks as well as everyday use. For example:
- Container Station supports various container applications and provides support for QIoT Containers and IoT applications.
- Virtualization Station allows users to run multiple Windows, Linux, UNIX, and Android-based virtual machines.
- QmailAgent centralizes multiple email accounts and simplifies daily email management. Qcontactz centrally stores and manages contact information.
In addition, QNAP’s new vertical NAS uses advanced virtualization technologies to integrate QTS and Linux. Installing Linux Station and connecting a keyboard, mouse and display, allows the TS-453Bmini to be used as a makeshift Ubuntu PC. The NAS also supports 4K UHD output and real-time transcoding, which provides smooth and high-quality video across devices and where network bandwidth is limited.

he 5N2 is Drobo’s 7th new product after undergoing an organizational management overhaul in 2015, which has represented their shift to an emphasis on simplicity and streamlined consumer experience. These new objectives are aptly addressed in their new 5-bay NAS, which seems to have been designed with the user in mind. While the importance of a streamlined user experience can’t be understated, the market has come to expect strong performance numbers thanks to companies like Synology, QNAP, Netgear, Seagate and Western Digital. The 5N2 includes several novel features that are worth noting, including mixed drive size utilization and at-a-glance storage monitoring. Drobo also added a few of their business features to the 5N2, including SSD cache and dual Ethernet ports.
Drobo designed the 5N2 to be as user-friendly as possible, which is first enjoyed with its easy deployment process. Thanks to simple instructions and great drive compatibility, it’s reasonable to expect that almost any user could get their 5N2 up and running, regardless of prior technical experience. The 5N2 can accept any combination of drive volumes, which isn’t common in competing brands (although this will probably affect performance). Two or more 5N2 units can be unified under DroboDR, which backs up user data in the event of drive or system failure. The 5N2 also comes with an internal battery that kicks in during power outage and further protects against data loss by flushing the system RAM to the persistent storage.
Drobo also designed their browser interface (myDrobo) to be as simple and approachable as possible, even for entry-level users. Although many of Drobo’s apps are embedded in the functionality of the 5N2, some helpful apps remain available to the user, including DroboAccess (for remote access) and DroboPix (for management of mobile photos and videos). Overall, Drobo doesn’t offer a very extensive app library, especially when compared to other popular NAS platforms, but there are quite a few options.
The Drobo 5N2 carries an MSRP of $499 (driveless), and includes a 2-year warranty.

Design and Build
The Drobo 5N2 probably uses the same chassis as its predecessor (the 5N) albeit with a few small changes. The NAS has a standard rectangular shape with a black finish and a very simple layout, although Drobo does include a limited edition GelaSkin magnet with purchase (at the time of this review’s publishing). There are five large LEDs oriented vertically along the right side of the device’s face, which correspond to each drive’s status. There is another line of small blue LEDs oriented horizontally along the bottom, which correspond to the system’s current data usage (in intervals of 10%). The system power LED is found at the bottom left-hand corner, and the LAN status LED is located at the bottom right-hand corner.
The back of the device is very simply laid out, with most of the surface area encompassing ventilation holes. The ports are oriented along the bottom, with two ethernet ports, one Kensington lock port, the power port, and the power button (from left to right).
On the bottom of the device is the small panel that pops off and enables users to install an mSATA drive for SSD cache.
Drobo’s management interface (Drobo Dashboard) is fairly intuitive overall, and first-time users could probably figure out how to deploy and troubleshoot their 5N2 without much trouble. The home screen gives a general overview of the 5N2, with navigation along the left side of the screen. Users can immediately see whether or not their 5N2 is functioning properly.
The status tab yields a more comprehensive assessment of the 5N2’s functionality and information, including the health of each installed drive, the serial number, firmware version, uptime, and hot data cache (SSD cache). Network information can also be accessed through the status tab.
The capacity tab shows the total capacity of the 5N2, as well as the used space and available space.
The status of each created share folder is accessible through the Shares tab. Users can also use this tab to create new shares, and adjust administrative settings.
Drobo’s disaster recovery feature can be activated and managed through the DroboDR tab. The 5N2 can be assigned as either a source or target for backups, and users can schedule routine backups at a specific time.
Users can deploy Drobo’s various applications through the Drobo Apps tab. Although Drobo includes several of their own apps (e.g., myDrobo, DroboAccess, DroboPix), users can also download various supported third-party apps through the same tab.
The Tools tab allows users to interact with the 5N2 remotely, with functions like system shutdown, restart, system rest (factory reset), and system update.
The Drobo settings tab has the dual disk redundancy setting (to protect against two simultaneous drive failures) as well as disk drive spindown (more or less a hibernation function). Users can also dim the LED lights of the 5N2 through this tab.
Testing Background and Comparables
The Drobo 5N2 will be compared two similar NAS units, including the Synology DS1515+ and the Synology DS1515. We also tested the Drobo 5N2 under two separate conditions; one with only HDDs installed, and one with an SSD installed (and SSD cache activated).
Our enterprise hard drive benchmark process preconditions each drive into steady-state with the same workload the device will be tested with under a heavy load of 16 threads with an outstanding queue of 16 per thread, and then tested in set intervals in multiple thread/queue depth profiles to show performance under light and heavy usage. Since hard drives reach their rated performance level very quickly, we only graph out the main sections of each test. Although we typically include several metrics for each of our performance profiles (i.e., throughput, average latency, max latency, and standard deviation), we will only be providing throughput results for this review.
Our Enterprise Synthetic Workload Analysis includes four profiles based on real-world tasks. These profiles have been developed to make it easier to compare to our past benchmarks as well as widely-published values such as max 4k read and write speed and 8k 70/30, which is commonly used for enterprise drives.
- 100% Read or 100% Write
- 100% 4k
- 8k (Sequential)
- 100% Read or 100% Write
- 100% 8k
- 128k (Sequential)
- 100% Read or 100% Write
- 100% 128k
In the first of our enterprise workloads, we measured a long sample of random 4k performance with 100% write and 100% read activity. When configured without SSD cache, the Drobo 5N2 posted 75 IOPS read and 445 IOPS write. With mSATA cache, we saw improvement in read performance (665 IOPS), but also surprisingly saw a reduction in write performance (336 IOPS). These values were in the ballpark of the other NAS units; the Synology DS1515+ posted 365 IOPS and 546 IOPS (read and write, respectively), and the Synology DS1515 posted 353 IOPS and 255 IOPS (read and write, respectively).
Our next benchmark measures 100% 8k sequential throughput with a 16T/16Q load in 100% read and 100% write operations. The 5N2 really suffered under these conditions, yielding only 9,731 IOPS read and 8,794 IOPS write. Once again, configuring the 5N2 with SSD cache, which should enhance performance, reduced its numbers in both read and write (9,161 IOPS and 7,605 IOPS, respectively). These numbers are really put into perspective by the Synology DS1515+ (51,982 IOPS and 43,948 IOPS in read and write, respectively) and DS1515 (40,676 IOPS and 30,617 IOPS in read and write, respectively).
The last test in our small NAS Synthetic Workload testing is the 128k test, which is a large block sequential test that shows the highest sequential transfer speed. Under these conditions, the 5N2 posted 231MB/s read and 227MB/s write without SSD cache, and 226MB/s read and 227MB/s write with SSD cache. The Synology NAS units doubled this performance; the DS1515+ posted 462MB/s and 446MB/s (read and write, respectively), and the DS1515 posted 454MB/s and 434MB/s (read and write, respectively).
Although Drobo’s new 5N2 includes several features that would appeal to entry-level users, it doesn’t stand up to modern performance standards. In most of our performance benchmarks, the 5N2 was completely outclassed by our selected comparable NAS units (Synology DS1515+ and Synology DS1515). In our 8k sequential benchmark, the 5N2 was outperformed by its competitors by a factor of five, the Drobo saw read performance of 9,731 IOPS and write performance of 8,794 IOPS compared to the slower Synology’s 40,676 IOPS read and 30,617 IOPS write. In our 128k benchmark, the Synology units with four 1G network ports available doubled the 5N2’s performance, 454MB/s read and 434MB/s write for the slower Synology versus the Drobo’s 231MB/s read and 227MB/s write. To make matters worse, Drobo’s SSD cache feature, which is designed to utilize the benefit of faster SSD transfer speeds, slowed down the 5N2 more often than not.
That said, if Drobo can improve their substantial performance and quality control issues, their products could be appealing to some users; one thing that the 5N2 has going for it is its extreme simplicity and ease of use. As private cloud computing continues to creep its way into the mainstream consumer storage market, the need for an ultra user-friendly option is becoming much more relevant.
- User-friendly interface
- Intuitive drive installation
- Poor overall performance
- Drobo’s SSD cache isn’t worth the cost of buying an SSD to load in the slot
The Bottom Line
Although Drobo still has much to address in terms of performance and feature content, their experience-oriented approach to cloud computing could help hoist them onto the playing field in the future.
