I purchased a used like new DS925+ w/ extra 30% off coupon the day after they announced the change. I can confirm operation (with no warnings) with random WD and Seagate HDDs I had laying around at the time. However, this did require updating the Diskstation Software to (re)gain native compatibility.
Also, apparently there has been a simple storage DB update script that (re)added support for non-Synology branded drives when the 3rd party HDD policy (compatibility ban) was in effect… but this should have never been required.
Given the early experience with the DS925+, I purchased a DS1525+ and 10GB NIC from B&H around BF. (I needed the extra bandwidth.)
I also purchased two OWC 64GB (32Gb x 2) DDR4 ECC SO-DIMMS kits. All 64GB was detected in each and both systems booted, but neither could consistently pass the build in MemTest. All 4 dimms passed individual memory tests in any of the 4 memory slots but no two pairs (64GB) would pass consistently. We were not able to determine if this was a memtest / Diskstation software limitation or a deeper hardware compatibility issue.
However Synology does not sell a kit over 32GB for these units and does NOT advertise 64GB compatibility. I ended up returning one of the 64GB kits just before the end of the return period. I kept the other and split for a 32gb dimm in each unit. (These kits along with most ECC Ram more than doubled in the ~3 week period while I was troubleshooting… so there was no way i was going to return both kits.)
No other problems so far out of either the DS925+ or the DS1525+.

As for price, the lowest price I can see was from late last year after they backtracked from their Synology-branded hard disk policy. It was $512. This deal is still an excellent price for this model, though.
And that is OLD info related to a policy they have publicly backtracked on.
Should they have put the restrictions in place to begin with? NO.
Do the prior restrictions currently apply to this NAS? NO.
What prompted you to investigate the ram, and increase it, what's your use case, does it improve performance that much?
Unfortunately HDD Storage prices have been stagnate over the last several years and are now seeing a bump up in pricing due to the recent AI / Data Center land grab… so good deals are harder to find.
One strategy to keep cost per TB down - Buy 4-5 midsize drives rather than 2 or 3 of the largest capacity. Price per TB usually hits a sweet spot 2 to 4 sizes down from max capacity. We are talking about ~14 - 18TB and maybe 20TB drives at this point in time.
Over the last ~8 years I've moved toward WD white label reds (drive shucks from WD Elements and EasyStore external enclosures) and more recently toward retail WD Reds… but only when I can catch them on a good sale as MSRP pricing can be ridiculous.
Some people like the value of Hitachi UltraStars that have been pulled and resold from data centers. I would consider these, but only if you will have least 2 or more easily accessible (automated) backups of any high value data. Others like Seagate Exos and Ironwolf drives which I expect are decent choices but pricey.
Some of the best priced drives are the Seagate barracudas. But I would NOT trust barracuda drives for anything other than a 3rd / 4th backup or very temporary storage. Seagate's barracuda drive reliability over the last ~10 years is just to risky for me.
Stay away from shingled drives…. Particularly for NAS use or anything other than low volume archive use. I've had these fail for no explainable reason.
As for the RAM upgrades - I'm planning to migrate / rehost some legacy VMs directly on these Synology NASes. This is part of an effort to retire an older Windows based hyper-v host that also doubled as a media server and media file share. 64GB is overkill given the CPU core count in these NASes, but was in my budget at the time. Also most of my larger media files are about 50 - 60GB, which could have been completely cached in ECC RAM during a file copy to the NAS - masking any HDD write throughput delays.
32GB is still probably overkill for my use cases. But I do plan to explore adding an NVME drive or two as a cache in leu of the extra RAM…but from my (limited) research this is a little more complicated.
However with current RAM prices - I would not upgrade DRAM at this time unless you need to host VMs, large numbers of containers, etc and can justify the premium for ECC DRAM.

I recently got a good deal on two 22TB WD Red drives, and was able to mix those in with my existing array of 8TB drives. Saved a lot over having to migrate all my drives to a larger size all at once. With RAID you can't just pop in different sized drives like this and have it work, at least to my understanding. Happy to stand corrected if that's not true.
