After testing I'm quite pleased with the DS1019+, build quality hasn't changed, and neither has the iconic design of the DiskStation. Synology still offers the metal structure and plastic enclosure we have become used to, each drive bay is lockable and has its own activity LED to the right.
With this solution taking advantage of the same platform as the entire DS+ lineup, Apollo Lake, it's no surprise we have a nearly identical performance curve. That said, the DS1019+ is an attractive option for anyone coming into the DSM ecosystem or anyone that is still on the lower tiers, such as the 218+ or 718+. For users rocking the 918+, this solution is not an upgrade, nor do I think Synology intended for it to be.
With that, performance of the 1019+ reached a peak of 116 MB/s in sequential read and write while workloads had it on par or slightly better than the DS918+ with a peak of 1300 IOPS in database, 1100 in File Server and 800 IOPs in Workstation.
Closing this out, the DS1019+ is a great solution and certainly bolsters Synology's portfolio, but it also highlights the need for the market to break past gigabit ethernet as its standard connectivity. As seen in testing today, sequential performance was pegged at 116 MB/s read and write throughout most test scenarios, and NVMe cache only made a discernable difference in 4K workloads. Hopefully, as the consumer networking market changes with WiFI 6 introducing 2.5Gbe to the masses, we see NAS vendors move in the same direction.
The Bottom Line
The DS1019+ is a solid upgrade for those already in the DSM ecosystem or a SMB that needs the capacity five-bays can provide.
