Yes, every time there is a new OS update, old NAS systems need to do more and more work with the same hardware. It gets really difficult with the new DSM7. This is why Synology have set a life expectancy of their products no longer than 10 years. This is where they stop supplying any updates.
Creating metadata during the indexing process will get slower every year. This includes data transfer speeds. Especially with small files where CPU need to work harder. Replacing one or two bays with SSD and installing DSM and app on this media will speed things up. But you will need to reset the system.
You can also connect directly if you have multiple LAN ports. This will give you full bandwidth of that LAN connection (either 1Gbe or 10GbE). Some models have 2 or 4 LAN connections. All of these can be connected to a router/switch. The load balancing function will use all lanes to deliver data.
DS1621+ seem to be older model, but it has two extra cores on the CPU. This is quite helpful if you also use NAS for other things like virtual machines. Dual-core models are good for home / soho office. Otherwise, all of these Ryzen-based models can deliver 10gbe speeds.
When deciding what is more important, it is surely the CPU. RAM can be upgraded, but CPU will not. Having a quad-core CPU will ensure 10 years of life span. DS1621+ still has 8 years on the clock. DS1522+ comes with 10 years support https://www.synology.com/en-uk/products/...621+/DS923+

I would connect via Thunderbolt/10GbE adapter if there was only one user. But technically this adapter will cost similar to a 2 port 10gbe switch. So maybe it is something to consider. https://nascompares.com/2018/01/19/cheap...-switches/
You can connect directly to your PC and a router at the same time.
Filling your NAS with Pro drives is not a bad choice. It gives you a 5years warranty. But it is also noisy if you keep your NAS on a desktop or living room. WD Red Plus drives are quieter and are non-CMR type of drives. The new DS923+ will support NVMe to be used for DSM and app. This could eliminate noise completely. HDDs can then be used for archives and other less often accessed data storage.
Older NAS such as 415play can be used for automated backups with no problems. You could even set it up RAID0 with no drive redundancy to increase the performance.
SSD cache is only useful for business environments, virtual machines, web servers etc. It serves as a boost for HDD RAID where SSD RAID is not an affordable option.
I hope this helps.
Thank you for your support, this really helps us go.
