ds1817+ or ds1819+
After about 2 years of service my ds1815+ fi,nally died (as expected!). My dealer has been very helpful, and has offered a ds1817+(8GB) or a ds1819+(4GB) as replacement. For some reason the ds1817+ (2.4GHz Atom C2538) is listed at about $80 more than the brand new ds1819+ (2.1GHz Atom C3538). Which one should I choose?
There is no noticeable difference between 1817+ and 1819+ unless you upgrade to 10GbE or link aggregate 4 LAN ports at the back (achieving 50% faster write speeds). Also, Synology may struggle with a availability for new models at a very early stage of release. The only reason to go for 1819+ is that you can upgrade the RAM to ECC type which is very useful for virtual machines/ web/ DB server.
New Gen3 x8 slot will support NVMe caching which is amazing improvement. DS1817+ was limited to SSD (550MB/s) SATA speed. New DS1819+ allows NVMe (potentially 3000MB/s) for internal speed increase and higher IOPS. This is useful for those willing to run web/database server.
Otherwise old model is just a better value for money as they have dropped the price.
You are comparing 4GB and 8GB NAS models- this is why it seems like DS1819+ is cheaper. Both NAS models will be very similar in price and most likely older model will be cheaper to clear the shelves.
