DS918+ and TS-453B /Be 16GB upgrade warranty

I am leaning to get a qnap TS-453Be over a sinology DS918+. One of the main reasons is the expandability of RAM to 16GB as you describe, which I have not read is possible for the 918+.
I am just making a few assumptions that I would like to confirm with you before pulling the trigger:
1) the expandability to 16GB is possible for the 453Be as well (in addition the 453B and 453BT3 as in your video)
2) the expandability does not depend on the original amount of RAM. Hence, planning on the upgrade, it makes sense to get the cheaper 2GB model

Also, when do you recommend to perform the upgrade? I was thinking that since the upgrade voids the warranty, it makes sense to first use the NAS as it comes for a reasonable amount of time so that any possible defect might show up. I would like this initial period to be not too long (especially getting the 2GB model) but not too short and have problems surface just after I voided the warranty. Do you have any recommendation on the length of this “trial period” or on a particular sequence of tasks to perform that would make potential hardware issues manifest themselves as soon as possible?

Both NAS features the very same Intel Celeron J3455 which supports max 8GB RAM per slot (x2 means max 16GB). Both are expandable and are tested working perfectly fine with 16GB upgrade. Only Synology have threatened voiding warranty if main RAM stick is removed or non-Synology RAM stick is used. With that being said it will be very difficult for Qnap or Synology prove that RAM was a reason of a damage caused to a NAS. It is literally impossible to damage a NAS with alternative NAS stick- this is just their way of upselling their products. Alternative sticks are identical RAM sticks, but Synology and Qnap happen to stick their label on top of it. So green light for upgrading either of these – DS918+ or TS-453B (including 453Be).

If you are not sure you need this much RAM, you can always upgrade the RAM at any time in the future. Once you start installing apps and playing with virtual machines you will see whether more RAM is required. I hope this helps you to join NAS community – the creation of endless possibilities! Enjoy!
