Question NAS Hardware Upgrade vs File Copy/Paste Transfer Times

My NAS is a newly resurrected (was never used - sat on shelf) 2012 vintage Synology DS212 with two new Seagate IronWolf Pro, 4 TB, Enterprise NAS Internal HDDs in a RAID config that will tolerate a single drive failure. The DS212 has been updated to the latest firmware. My LAN is all 2.5Gb but the DS212 only has a 1 Gb port. Bottom line, the actual transfer speed, when copy/pasting a file from my desktop to the NAS, is only typically 30 MBs. A typical already encoded zip backup file is 1.4 TB so it typically takes the better part of a day to complete this transfer. This is much too long. On infrequent occasions some error causes the transfer to end and that, of course, requires starting all over again, usually the next morning.

I want to replace the DS212 with a UGREEN NASync DXP4800 Plus 4-Bay NAS. It not only has a much more powerful CPU it also has 2.5/10 Gb ports although the intervening switch (between my 10 Gb desktop port and NAS) is only 2.5 GB. I would like to get some sort of feel for the actual copy/paste transfer rates I would then achieve. I would also like to understand if replacing the switch with a 10 Gb switch will give some worthwhile bang for the buck (all intervening cables Desktop to NAS are Cat 8).

Also, would replacing the HDDs with SSDs or M.2 drives provide any consequential increase in transfer times?

In other words, 30 Mbs is painfully slow. I don't not mind spending the money for new hardware if that will provide a substantial improvement. The upgrade cost is too much for only an incremental improvement. It would be helpful to have some real-world experience by others to better make this decision.

I glanced at some old reviews for the DS212 and the best case scenario for RAID-1 writes is about 60 MB/s. You're getting only half that.
Without exhaustive testing, it's tricky to say what component swaps will be the most impactful.
Right now I don't think the LAN is the bottleneck, but the I/O subsystem itself: the drives and the SATA bus it rides on.

If you swapped out only the NAS, you'll probably get closer to 100 MB/s for sequential writes. Let's say that's 3 times faster than now. Is that worth the $700 investment?
If you also upgrade to SSDs, then you'll see even better disk I/O performance.
Depending on your budget and use cases, this gets expensive quickly for a "home lab."

Before buying new toys, you can consider your backup methodology itself. Do you need to transfer the full 1.4TB every day? Can you instead switch to incremental backups?
Are you using Hyper Backup to protect against catastrophic failure of the NAS?
