DS1819+ vs TS-873

QNAP or Synology

I have watch hours and hours of your youtube videos and thought I would ask the point straight out. I had my mind set on the DS1819+ from synology and was going to up the ram to 32 GB and add a combo m.2 and 10gbe interface and already have 8 x 8TB Seagate Iron Wolf drives. Then came along a comparison with the TS-873.

So what I should explain is the usage case. Some background – I am about to replace a 6 server EXSi cluster with 3 Dell R640 servers with vmware 7 and an EMC SAN array (13TB all flash) attached via SAS 12GB SAS using DAC cables. The servers each have 6 x 10gbe and 2 x 1gbe interfaces and will connect to 4 x 4112-on Dell switches at TOR – two for servers and storage and the other 2 for core network. The NAS will be used to backup the ESXi vm’s pull down/sync various backups from our Oracle Cloud environment – I do this now using a rsync on FreeNAS. I would also like to replicate the vm backups to a freenas box on-prem as well as possible connect and backup cloud compute instances in the Oracle Cloud.

Your comments re qnap and cloud stuff muddied my thoughts hence the email. The DS1819+ and TS-873-8G with dual M.2 drives, combo card and ram upgrade are within my budget.


I can understand the dilemma. Both of these NAS models are very similar to their performance. But Qnap will be a faster option if you plan on upgrading with PCIe card.
With a combo card, the PCI lane will need to cope not only with fast access to NVMe cache but also push through 10Gbit via Ethernet. This will potentially limit its speeds to that single 10GbE or less depending on use case. But with Qnao cache has its own PCIe lane dedicated. You can then add a dual 10Gbit card and get a much faster backup speed when enabling load balancing/link aggregation.

I hope this helps.
