ASK NC

Regular consumer of your videos and just watched re 923+. Slowly moving to 10Gb network on all Unifi kit. Installed E10G21-F2 some time back. Now wonder if I can/should upgrade further: RAM from 4 to 32; does space permit E10M20-T1 PCIe Card or alternative cache. Waiting/hoping for newer/better model which incorporates these add-ons and would then use existing 1618+ for cameras and multiple computer back up only. Thanks again for all the good work.

Adding more RAM will only improve performance if you already use more than 50% of it.
DS1621+ is the latest plus series and ds1621XS+ also has 10GbE port.
Adding NVMe cache is something beneficial if you have multiple users or if you do video editing.

I hope this helps.
