SUMMARY: The NETGEAR ReadyNAS RR2304 supports the complete suite of features in the ReadyNAS OS, including ReadyDR disaster recovery, data protection, and virtualized storage for VMware and other virtualized networks. The device’s ReadyCLOUD ecosystem provides users with a secure personal cloud with an integrated, automatic VPN connection. According to NETGEAR, this NAS device “represents a significant upgrade in terms of storage features and performance available for small businesses,” as the ReadyNAS RR2304 also supports workgroups of up to 40 employees.


  • Has a powerful 64-bit Dual Core Intel Celeron processor.
  • Two Gigabit Ethernet ports and three USB 3.0 ports for additional storage and transfer.
  • Automatically installs ReadyDR to ensure business continuity.


  • A somewhat clunky interface.
  • The mobile app could use an update.
  • Users must buy hard drives separately.

OUR TAKE: In terms of data protection, the NETGEAR ReadyNAS 2304 is unmatched. With Btrfs File System Flex RAID protection against disk drive failure, real-time antivirus, incremental backup copies, and bitrot protection, users can be sure their data is safe. The device also offers versatile sync and remote management capabilities, enabling employees to utilize the same unified interface, regardless of location. However, buyers should be aware that the NAS’ hot-swap functionality is limited to replacing failed drives only.


Synology 2 Bay NAS DiskStation DS218Best of Solutions Review

SUMMARY: The Synology DS218 offers storage capacity that enables users to create their own private cloud and maintain total control over their data. This device also delivers QuickConnect, which allows users to connect through a simple, customizable address, so they can instantly access media and work files on any Windows/Mac/Linux computer, laptop, or mobile device without an additional charge. Additionally, Synology provides a range of mobile applications, allowing users to access their multi-media library, even when they’re on the go.

OUR TAKE: The Synology DS218 is a great fit for home users looking for an affordable storage repository for file sharing, PC backup, and multimedia services. If users are looking for a less expensive option, they could consider the DS218play. However, buyers should be aware that the DS218play does not offer hot-swap drive bays. However, both of those devices provide 4K video transcoding capabilities, which is the feature that differentiates these models from their competition.


Asustor AS5202TBest of Solutions Review

SUMMARY: The Asustor AS5202T provides seamless cross-platform and multi-user access, enabling users to easily connect to their device from Windows, Mac OS X, or Unix-like operating systems. The device also offers Snapshot Center, a new feature allowing devices to utilize BTRFS and iSCSI volumes to take snapshots of the information inside a NAS. This capability supports up to 256 snapshots of a volume and can be done every five minutes, creating a backup that can be restored if data is lost or damaged.

The device supports Emby and Plex media servers, which allow users to keep their videos, music, photos, and other personal media organized and ready to view on-demand. According to TerraMaster, the F4-210 “supports several array modes, including RAID 0, RAID 1, RAID 5, RAID 6, JBOD, and SINGLE, as well as HTTP, SMB/CIFS, AFP, FTP, NFS, and WebDAV.” With regard to privacy, the F4-210 also enables users to tailor access rights as needed, at no extra cost.


  • Relatively inexpensive.
  • 4K video transcoding.
  • Speedy file transfer rates.


  • Limited application library.
  • Only has one LAN port.
  • RAM is not upgradeable.

OUR TAKE: The TerraMaster F4-210 is designed to act as a home or personal cloud solution. The device’s differentiating factor is its low price, but buyers should note that some features are sacrificed to offset this. The device does not offer capabilities including multiple gigabit LAN ports, link aggregation, or an HDMI video output. The F4-210 is also relatively easy to install and manage through the TOS operating system, but it does not offer a large number of downloadable applications, especially when compared to competing devices. If you have a larger budget, a comparable NAS with additional features is the aforementioned Asustor AS5202T.

OUR TAKE: We recommend the WD My Cloud EX2 Ultra for use in the home or a small business, as this device fits in the space between WD’s consumer-facing My Cloud and its four-bay business storage solution, the My Cloud EX4. The My Cloud EX2 Ultra has a similar set-up process as the My Cloud Home device while also offering some of the more advanced features of the EX4. Though the device comes with WD Red NAS hard drives, if you would rather build your own system, you have the option to choose the diskless model and add compatible drives yourself. With good overall performance and competitive streaming and backup capabilities, this NAS is a great fit for the home or small offices.

The complete system offers Intel AES-NI encryption, 4K media streaming, and real-time transcoding. Users can also rest easy, as the device comes with a two-year warranty with the option to purchase a three-year warranty extension. While the choice to not include 2.5GbE ports is a bit of a headscratcher, for its price, the TS-451D2 is a great media service for home use and business surveillance jobs.
