Synology 4-bay NAS DS415+ ~ Advantages & Limitations


The Synology DS415+ 4-bay NAS (Network Attached Storage) is a good appliance-based external storage/backup option for homes and small businesses. Once you connect this device to the network, you can store a bulk of your data (files and media) here and access when required. This saves a lot of space, especially on mobile devices. Even multiple people in your network can access the NAS simultaneously.

This NAS system is almost a private cloud that allows you to store and access your content without the need for Internet connection or yearly storage charges. It can also be connected and synced to a public cloud. If you want, you can access the NAS and its contents from a remote location, over the net. The Cloud Station app provides automatic backup of data from computing devices – you can sleep in peace knowing your data is safe, even if you forget to take an external backup.

Advantages of Synology DS415+ NAS:

  • “Backup & Replication” allows users to schedule automatic backup and restore the drives to any previous point in time. This keeps data available even in cases of accidental deletions.
  • The 2 GB of memory is placed on a regular memory slot instead of being soldered into the system, opening the possibility for memory expansion in the future.
  • This model supports different RAID levels including SHR, RAID 1,5,6,10 for disk-level redundancy. If you use RAID, even if one disk fails you don’t lose any data as the NAS unit can rebuild all the data ŏnce a new one is inserted.
  • Screwless drive installs provide for easy & quick drive installations and replacements.
  • GUI-based monitoring software makes it easy to edit settings. Synology’s GUI is famous for its user-friendly interface.
  • It is possible to install and run Plex media server in Synology DS415+. You can search how to do that on the net.
  • Silent, small, easy to use & fast.
  • It is possible to use the Synology 416+ as a private cloud to stream media and backup files from various computers and mobile devices automatically, without any monthly fees or Internet data as required by online cloud providers. Besides, private cloud is faster and secure.
  • The Quad Core CPU is powerful enough for multiple 720p video transcoding. This powerful processor may make this unit even better than DSM416play, for multimedia applications.
  • Synology DSM’s capabilities could be extended using many apps, provided by both Synology and third-party. These allow the user to turn their storage server into a web server, surveillance server, DNS server, iTunes server, VOIP server, radio server, VPN server, RADIUS server, email server, file server, backup server, etc.
  • Synology is one of the most popular NAS brands in the market today.
  • It works with Time Machine and is compatible with other popular OSx apps.
  • You can install and stream movies via Plex media server.
  • You can connect Windows, Mac, Linux, Apple and Android devices to it.
  • The two LAN ports can be combined together using Link Aggregation if you want a higher throughput.
  • Users can integrate this unit with Active Directory or LDAP directories.
  • It is possible to access the NAS from a remote location using a computer or a mobile, over the Internet.
  • It has a recycle bin so you don’t accidentally lose data.
  • Hard-drives are hot-swappable: You can replace them while the machine is in operation.
  • Supports iSCSI targets; so it can be used in small business environments in addition to homes.
  • You can insert SSD drives into this unit, if you want to.
  • Two of these Synology NAS units can be combined in an active/passive configuration where one automatically takes over if the other fails.
  • Folders synced by DSM can be encrypted, for additional security.
  • Supports Wake on LAN/WAN and scheduled Power ON/OFF, to save power.

Tips:

  • Try to connect the NAS unit to a Gigabit switch, for better performance.
  • To use the Link Aggregation feature, use a network switch that supports that feature.
  • Try to use Enterprise-grade Hard Drives built for NAS like WD Red as these are more reliable and are built for 24×7 operation.
  • To enable the backup/sync functionality, download the Cloud Station server app on the NAS and download the Cloud Station client apps in the machines you want to sync to. You’ll find it here: https://www.synology.com/en-us/support/download/DS415+
  • Try to connect the NAS through a UPS to take care of power failures. You con configure this unit to automatically switch off once the power supply switches over to the UPS supply during a power cut.
  • You can install any number of drives (for eg. 2) and add more later on.
  • You need at least two drives to enable disk-level redundancy.
  • You could install Plex on your computer and map the folders to the network drive on the Synology NAS.
  • RAID offers protection from individual drive failures, but it reduces the total available storage capacity. Try to use Synology Hybrid RAID as that has the best storage efficiency, but remember it is proprietary.

Limitations of Synology DS415+ NAS:

  • Each version of Synology OS (for different models) has slightly different User Interfaces, and that might make it difficult to manage multiple Synology units, if you have.
  • Software-based RAID, not hardware-based.
  • No redundant power supply.
  • Synology Surveillance Station includes license for only two cameras out-of-the-box. If you want to manage more IP cameras through it, you need to pay around $50 USD per camera license.
  • You can upgrade the memory in DS415+, but that may void the warranty. Also, the hardware construction makes it difficult to change the RAM module.
  • Rebuilding a disk array (replacing a failed disk or removed disk with a fresh one) in an active RAID mode takes many hours to complete.
  • No SD Card slot.
  • Some users have complained that Synology doesn’t take up out-of-warranty repairs, even if the users are ready to pay for them. Do check with the company on this policy, before buying.
  • The documentation could be more exhaustive and easier to follow.
  • No option to plug-in the faster 10 GE network card in the future, unlike a few competitors.
  • The diskless version of this NAS doesn’t come with hard drives. Users need to buy and install them separately. That increases the cost  – don’t forget to factor that in your budget.
  • There is only one USB 2.0 on the front, the two USB 3.0 ports are behind.
  • The USB ports are not designed to be connected directly to a computer; they can connect to external hard-drives. To connect to a computer, connect this unit to a network switch, and connect the computer also to the network switch (directly or indirectly).
