Compared with DS1019+, Synology DS1515+ provides faster read-write responses, enhanced eSATA and USB connectivity, and larger data storage but its noise production and price are relatively higher.
Lets start off with similarities and differences between both devices:
- DS1019+ is relatively lightweight, but it lacks M.2 SSD slots and has lesser USB and eSATA ports.
- DS1515+ shows faster speed and higher processing frequency.
- DS1019+ carries two relatively larger RAM chips.
- DS1019+ supports more cloud services for mutual synchronization.
- Both tools offer equal efficiency for data backups.
- DS515+ has more sharing capability.
- DS1515+ is a noisier device in comparison.
- DS1019+ is priced relatively lower than its competitor.
DS1019+ is equipped with a tetra core processor and two large-capacity memory chips.
Owing to the well-built structure, it shows superior temperature endurance and noise-free operations.
Besides that it allows a large number of FTP/SMB and server connections, accounting for more efficient collaboration on team projects.
DS1515+ is a similar-looking NAS, but it works faster than its competitor.
In-built M.2 2280 slots have increased its SSD holding capacity up to seven disks, and more eSATA connections provide greater options for storage expansion.

Side By Side Comparison:
| DS1019+ | DS1515+ | |
| Processor | Intel Celeron J3455 4 core | Intel Atom C2538 4 Core |
| Internal memory | 2 x 4GB DDR3L | 2GB DDR3 |
| Drive types | (M.2 2280 NVMe SSDs) O 2 (3.5” or 2.5” SATA HDD/SSD) O 5 | (2.5” or 3.5’’ SATA HDD/SSD) O 5 |
Speed
DS1515+ offers faster performance than the contestant because its quad-core CPU processes the data at a higher frequency (2.4 GHz).
Link aggregation under RAID 5 further enhances its reading and writing speeds.
In comparison, DS1019+ carries a lower frequency processor, which takes more time to scan, store, and stream data.
Thus, it shows slower read-write functions reaching only 225 Mbps speed at maximum.
| DS1019+ | DS1515+ | |
| Processing frequency | 1.5 GHz, burst up to 2.3 GHz | 2.4 GHz |
| Reading speed | 225 Mbps | 450.77 Mbps |
| Writing speed | 225 Mbps | 396.50 Mbps |
Design
Layout and design features are quite similar for these two devices.
Both have five bays with swappable drives, black color, and a minimalistic look.
The front sections carry drive bays and status indicators, while fan exhausts, external ports (USB, Gigabit Ethernet, eSATA), and a reset button are visible on the backside.
DS1515+ is a relatively compact and lightweight device.
It provides comparatively larger storage volume as two M.2 2280 slots present on the rear side can hold 2 more SSDs in addition to five disks in the drive bays.
It also carries more USB and eSATA ports, allowing a better ability for storage expansion.
However, it shows less endurance to extreme temperatures and can be operated only in a smaller temperature range.
DS1019+ has a larger weight, width, and depth, and its ability for USB and eSATA connections is half as compared to the contestant.
Integration of two 4GB memory chips makes its installed memory larger in comparison, but it lacks SSD slots and provides a lesser volume for data storage.
These features make its design score lower in comparison.
Nonetheless, its casing and chip structure is more resilient to temperature extremes.
| DS1019+ | DS1515+ | |
| Dimensions (H x W x D) | 166 x 230 x 223 mm | 157 x 248 x 233 mm |
| Weight | 2.62 kg | 4.17 kg |
| No. of the drive bays | Five | Five |
| USB 3.0 ports | 2 | 4 |
| eSATA connections | 1 | 2 |
| 1GbE RJ-45 LAN ports | 4 | 4 |
Cloud storage
A Synology drive is associated with each of these systems for enabling cloud networking.
All data from your NAS is stored in this private drive, and you can access it from anywhere using DS applications and different platforms.
You can also transfer and sync data from public cloud platforms.
However, DS1019+ takes the lead for this feature as it provides mutual synchronization with more commercial platforms than the contestant.
On the other side, DS1515+ has the same cloud efficiency, but it shows support for fewer commercial cloud services.
OS and Internet browsers
In terms of OS compatibility, DS1515+ takes the lead because it shows compatibility with relatively earlier OS versions in addition to the latest variants.
Moreover, it allows operations with all leading browsers for online functions.
In contrast, DS1520+ stands below the competitor because it supports relatively latest versions only.
Likewise, it is compatible with advanced versions of web browsers.
Backup
These Synology products are equally efficient for backing up data.
They will provide you with multi-layered backups and various remote backup systems.
Both tools enable RAID versions up to RAID 10 and integrate Synology Hybrid RAID, the exclusive technology of Synology, presenting maximum mirroring efficiency.
Moreover, the 5-bay interface allows 2-disk fault tolerance to both these devices.
For remote backup, hyper backup and Synology active backup suite allow total reservation for your data at a remote database.
Moreover, both devices allow integration with 40 IP cameras, keeping their footage safe in good resolution.
Sharing ability
DS1019+ offers better networking ability as its data-sharing specifications are superior to its competitor.
It has 4x better capacity for FTP concurrent connections, VPN connections, and shared folder synchronization.
In contrast, DS1515+ scores lesser points for its sharing proficiency.
Although it permits the same number of local user accounts, shared folders, and local groups, its capability of concurrent FTP/SMB and VPN connections is just one-fourth of the competitor.
Also, it shows slower synchronization of shared folders as it can handle fewer tasks at a time.
Setup
Both DS1515+ and DS1019+ can be set up and configured easily as their disk drives are swappable, and user manuals provide a complete step-by-step tutorial for installation.
- To install a storage disk, take out a drive tray.
- Mount the disk over it and fix that with screws.
- Put the drive back and power up your device.
- Provide internet connection via a router and install DiskStation Manager for cloud configuration.
Noise
DS1515+ is relatively noisier than its opponent, marking a higher value on the decibel scale.
Its increased sound production is due to the integration of two large-size fans for cooling purposes.
Conversely, DS1019+ has smaller fans that operate with lower sound production.
Resultantly, this device specifies a noise level below its competitor.
| DS1019+ | DS1515+ | |
| Fans | 2 | 2 |
| Fan dimensions | 92 x 92 mm | 120 x 120 mm |
| Noise rating | 20.8 decibel | 22.3 decibel |
Warranty
These gadgets are structurally robust and functionally well-configured; they provide optimized performance for several years.
Nonetheless, DS1515+ ranks comparatively more durable.
Its warranty period is 3 years, but a premium option is also available for 2 years extended warranty, providing a whole of 5 years warranty.
DS1019+ is fairly durable as well, but it only carries a 3 years limited warranty.
