[SOLVED] Add SSD as Cache to software RAID 5?

[SimplyTheBaron]

Bit of a niche question and not entirely sure how to do it/if it's even possible.

Currently, I have a software RAID 5 on Windows Server 2019 built from Disk Manager. It is 3x 3TB storage.

I have a separate NVME SSD (25G6GB) which is currently not being used in the system and was wondering if it would be possible to set it up as a cache to help with the write./read speeds of the drives.


Home Server Spec:

CPU: Intel i7 10700
RAM: 32GB 2666Mhz
MOBO: MSI MAG Z490 TOMAHAWK
OS: Windows Server 2019 10.0.17763 Build 17763

Unless you've set it up with Storage Spaces, the only other option I'm seeing using something like PrimoCache

No annoyingly did it through Disk Management than storage spaces, took a day and a half to build as well 🤦‍♂️I will give that a go and let you know how I get on

I'd be interested to see how much, if any, actual user facing difference there is.

What is this server used for?

Mostly Plex, Cloud storage with Nextcloud on a VM

Odd game server like minecraft

And apart from benchmark numbers, what actual benefit is the SSD cache doing?

Well so far when it comes to people outside my network running 4K HDR content doesn't seem to buffer at all anymore and that was the only thing that had changed. When transferring from Plex auto moves folders and renames them it is done more efficiently. Which then means when plexs scans the library content is available sooner
