Home lab Synology DS918+: which RAM, SSD (size)?


I posted this some time ago:

have a DS414 now, didn't buy a new one yet, since it was quite some money to spend for "just a home lab".

Now I've read that the Synology DS918+ (reviews are pretty good):
*only costs 550 Euro
*has quad core 1,5 Ghz, https://www.cnet.com/products/synology-disk-station-ds918-plus-nas-server-0-gb/specs/)
*also runs 16 GB (about 150 Euro for 16 GB)
https://forum.synology.com/enu/viewtopic.php?t=136028 has SSD cache built in
*is only using 100 Watt
*has SSD cache build in (without the need to buy an extra card)
*can run virtual machine manager: https://www.synology.com/nl-nl/dsm/packages/Virtualization

My current NAS = DS414 with 4 disks (Seagate Green -no SSD- basic disks) of 3 TB in RAID5 (still half of it is empty).
So I'm thinking of buying this DS918+ and buying 16 GB for about 160 Euro
=> crucial-8gb-ddr3l-1600-cl11-sodimm

Not sure about the SSD cache: would I need it and if yes which one and how much storage (128, 250 GB ...? they are quite expensive):

As mentioned, it is only for home use (1 user and running a vm from time to time), maybe other users will connect remotely and I might run a website on it.
So I'd spend 700 Euro for this upgrade. That's about the max I wanted to spend.

So please advise:
-about the Synology 918+: looks what I need
-about the ram: the crucial will do, right?
-SSD cache: will it be absolutely needed/will it drastically boost performance/will it be worth the investment. If yes, what disk size should I buy, should I buy two at a time and equal size or could I start with one ... thinking 'bout the budget. Could spend more on SSD cache if it is really worth the money.

Thanks for your input.

I think a HPE ProLiant MicroServer Gen8 or Gen10 is a better purchase and specification, running Windows 2016 Hyper-V.

Thanks but I do not want a nas AND a microserver.Had it before and it is not what I need. Had 3 microservers with esxi but no time anymore to maintain.

I just need low power consumption all in one box on which I can run occasionally a vm.
So please advise on type of ram and ssd cache needed or not then which size.

I'm not suggesting your build a NAS or ESXi Server but purchase a new HPE ProLiant MicroServer which is a far superior performing and lower power piece of hardware than a Synology low power box, which claims to do everything poorly. (the smaller, SOHO versions for home use, e.g. 2-4 slot versions).

Windows 2016 will allow you to do what you want to do, with an occasional VM.

If you want a Synology NAS, with all it's low power, in terms of performance, CPU, Memory etc

As for RAM you need to purchase what Synology has confirmed tested with their hardware. See Synology website for compatibility.

For your low usage I would not purchase SSD cache, if you find the performance is not too your like-ing later you can add cache.

What would the alternative on Hp Microserver be?
There are only 4 HDD and no ssd ... :-(

Plenty of space to add standard SSDs or PCI-e Flash Card.

and you may not even need SSDs.
