Synology DS918+ vs DS1019+

In comparison, DS1019+ has double the amount of installed memory, shows faster writing speeds, and has a better sharing capability, while DS918+ is compact and lightweight, has enhanced backup ability, makes lesser noise, and comes for a lower price.

Lets start off with similarities and differences between both devices:

  • Same quad-core processing unit is integrated into both these devices.
  • DS1019+ is a 5 bay while DS918+ is a four bay NAS.
  • DS918+ is lightweight as compared to its contestant.
  • DS1019+ presents a faster writing speed in comparison.
  • DS918+ takes the lead for its backup efficiency.
  • Sharing ability of DS1019+ is superior to its contestant.
  • DS918+ makes lesser noise while working.
  • Both devices come with the same warranty from the manufacturer.
  • DS1019+ is a comparatively expensive storage system.

Synology DS918+ is black-colored hardware having the same structural and functional elements as its competitor.

But it has fewer drive bays, so its storage volume is relatively lesser. Its enhanced snapshot technology accounts for more efficient local backup mechanisms.

On the flip side, the Synology DS1019+ looks identical to its competitor but has more drive bays and a larger storage capacity.

Moreover, it has two memory chips; thus, it comes with a vast internal memory.

It encodes the information relatively quickly due to higher writing speed. Moreover, its ability to share data is also enhanced in comparison.

Read-write speeds for both these devices are very close because they carry the same processing unit and memory chips.

Synology 1019+ shows read-write efficiency at the rate of 225 Mb per second.

Its writing pace is slightly higher than its competitor because its vast internal memory makes it easier to encode new data.

On the other side, Synology DS918+ works at 225 Mbps reading and 221 Mbps writing speed with encrypted throughput.

But link aggregation increases its transfer rates by one megabyte, and its speed becomes 226 Mbps read and 222 Mbps write.

Design and software

Both gadgets have many similarities and come with the same intel Celeron J3455 quad-core processor, a DDR3L RAM, and an identical black outlook.

Both these tools enable Synology Hybrid RAID (SHR), JBOD, Single RAID 0, 1, 5,6, and 10.

Their drive trays are hot-swappable and open at the front. LED pointers, a power switch, and one USB port are also located on the front panel.

The rear panel has two 1GbE RJ-45 ports, a reset button, fans, slots for eSATA connection, a power inlet, USB type-A input, and M.2 NVMe SSD slot.

Likewise, both tools can withstand temperature and humidity extremes.

Their storage temperature ranges from -20°C to 60°C.

Comparatively speaking, Synology DS1019+ has 5 drive bays and resultantly shows larger weight and width.

Moreover, it has two internal memory chips, so its installed memory becomes double (8GB) in comparison.

Furthermore, it can be used in relatively colder environments (even at 0°C) without compromising performance.

DS918+ is a lightweight and compact four bay NAS. It comes with one memory chip, and its installed memory is 4GB only.

The working temperature should be 5°C at a minimum for this device to work properly.

Cloud storage

Synology DiskStations are associated with Synology Drive, which provides a private remote database.

This unified portal stores all of the NAS data remotely, provides synchronization across different platforms, and enables users to access it from anywhere through DS apps.

Moreover, these tools allow two-way synchronization with many commercial cloud facilities like Google Drive, Dropbox, Baidu, OneDrive, Box, etc.

However, scores are higher for Synology DS1019+ because it has an additional drive bay as compared to its competitor, providing a comparatively larger storage volume.

OS and web browsers

Operating system requirements are the same for both these network-attached systems. You can manage these DiskStations through Windows, macOS, or Linux devices.

Collectively these tools support Windows 7 and 10, macOS X 10.11 or higher, Linux, iOS 10 or higher, and Android 6.0 or higher.

These systems work with Google Chrome, Firefox, Safari, and Internet Explorer for synchronization and web-based functions.


These devices provide a comprehensive remote backup covering PC, NAS, virtual machines, office, and G suite because many backup applications are integrated with both of these, including;

  • Hyper Backup stores copies of NAS files on local shared folders, linked cloud services, and Rsync servers. Hence, you have many options for data storage and retrieval.
  • Cloud Station Backup safeguards your desktop devices running on compatible OS. These also support Time Machine for backing up data from mac devices.
  • Synology Active Backup is a centralized backup solution for PC, VMware, office 365, and servers. This comprehensive feature makes these DiskStations business-friendly.

Synology DS918+ takes the lead for local backup due to advanced snapshot technology.

It enables up to 64 snapshot replications that reduce data errors and enhance mirroring efficiency.

On the other hand, Synology DS1019+ only permits 32 snapshot replication on maximum; hence, stored data is more prone to accidental damage.

Sharing ability  

When it comes to sharing and collaboration, Synology DS1019+ wins over its competitor because it shows better sharing ability.

It allows a larger number of FTP links for sharing data, reaching even up to 2000 connections at once.

It provides a better collaboration facility, enabling 1800 office users to work simultaneously.

Moreover, its proficiency for shared folder sync is higher than its competitor’s as it supports 32 tasks at a time.

In contrast, Synology DS918+ stands below the competitor because it can maximally support 1000 FTP concurrent connections and only allow 200 office users to collaborate through the NAS.

For shared folder sync, it can handle 8 tasks at maximum.


Both these systems are diskless enclosures, and you need to install storage disks to use the NAS.

However, their configuration methods are the same and convenient:

  • Slide off the disk tray from a drive bay.
  • Mount storage HDD or SSD on it and fix it with little screws.
  • Place the drive back into the empty disk bay.
  • Provide the power supply and internet connection. Now, use ‘web assistant’ to access DiskStation Manager (DSM).
  • Use the DSM web portal to set up your network-attached system.


DS1019+ is a noisier device than its contestant.

It produces more mechanical sound reaching up to 20.8 decibels on the noise scale.

Conversely, DS918+ shows a quieter performance; its sound level has been recorded at 19.8 dB during noise measurement.


Both of these DiskStations belong to the same NAS series; thus, their material composition and structural endurance rank the same.

These devices are equally durable and come with a replacement warranty for 3-year from Synology.

The company provides the new equipment if the device presents faulty operations despite fair usage.
