Synology DS3018xs Review

Intro

Synology unveiled its first 6-bay NAS, the DS3018xs, at Cebit in March 2017. It supports the optional dual M.2 SSD adapter card or 10GbE NIC for high-IOPS system cache and ultra-fast data transmission respectively. It can support up to 30 drives when used with two DX1215 expansion units. The DS3018xs sports a much newer dual-core 2.2GHz Celeron D1508 CPU. The XS series comes with 5-year warranty and advance hardware replacement through Synology Replacement Service (SRS).

Earlier this year, Synology also released the DS1817+ and DS1517+ which uses the 2.4GHz Atom C2538. Prosumers looking for a NAS might be tied between the DS1817+ and DS3018xs. Does their price difference warrant for the CPU, warranty duration and product replacement support? Compared to the DS1817+, the DS3018xs seems to be an energy guzzler.

    Excellent pros / cons analysis of these two prosumer NAS. I much prefer the idea of having a Celeron / Xeon-D processor with ECC memory for my data (it used to be branded Xeon-D). But I don’t need ultimate CPU speed for my usage. And the extra 2 bays, lower at idle power consumption and lower price tip me towards the DS1817+.

    Thanks for the comment! I am still trying to figure out the workloads suitable for the DS3018xs. At the moment, virtual machine manager runs pretty well on this NAS!
