Synology DS918+ SMB NAS Review
Conclusion Build quality is always pretty good with the Synology units, the 918+ coming to market as the replacement for the DS916+ offers a similar chassis build with plastics and metal skeleton. We have similar placement for LEDs and front-facing USB 3.0 ports. The 918+ did do away with the front bay cover the 916+ had. On the hardware side, Synology swapped from the Pentium N3710 to Celeron J3455 with the 918+, this offers a slight improvement in performance while retaining all of the hardware encryption and decoding features of the 916+. Memory platforms are the same between both units with DDR3/L support over two slots and max capacity at 8GB. Drive bays are the same although the 918+ does support NVMe m.2 on the bottom of the unit but both support the DX517 expansion chassis along with 10TB drive support and peak internal capacity at 40TB. The 916+ does have one more USB 3.0 port that has been removed from the 918+ otherwise the platforms are the same with dual GBE rounding things out. Performance of the 918+ in my testing was relatively good. We did have a few spots where results were low but overall, not bad at all. We started with single Client, NASPT. This gave us 108 MB/s with video playback and 118 MB/s video record. File copy touched 119 MB/s. RAID 5 was similar to RAID 0 in most cases reaching 115 MB/s in record and 115 MB/s in file copy. RAID 6 offered the lowest results with 93 MB/s playback and 111 MB/s file copy. The workloads all showed solid Database performance from the 918+ with Web Server and Workstation the two behind that. Real-data testing with SMB read and write showed all three RAID arrays performing up to standard moving data, RAID 0 bring in 116 MB/s, RAID 5 at 100 MB/s and RAID 6 86 MB/s DSM hasn't changed too much since our last article, with version 6.1 used in testing and 6.2 still in beta. Btrfs is one of the bigger features of this platform offering its self-healing file system, shared folder encryption and replication among others. For those that have IronWolf drives you will have access to IHM for a more accurate health monitoring of your drives and for those of you that are starting your march towards all-flash arrays Synology has deployed RAID F1.
