Storage Space Configuration

Windows 10 to be used predominantly as a media server but also a place to store general data files (word / excel etc.) documents. The host has an SSD drive which is used to boot the OS and then there's 4 x 4TB drives which can be used to store all the data.

I need some resilience for all of the data, but unsure of whether to carve up the storage so that there's a mirrored pool for the general file data (let's say just 100GB) and the rest to store the media files (TV, films etc). The media files pool I'm thinking of setting up as parity because it will provide more capacity than a mirror and performance will be OK for large, sequential reads.

Any ideas on the above configuration? Anybody else done something similar?

Use mirrored. Parity really does kill performance, even with large sequential reads. It's really only suitable for "cold" data, which is generally only a business issue.

Thanks for the quick response. I would prefer mirroring, but it absolutely crushes my available disk capacity. Tests I'd undertaken didn't show a massive difference between mirroring on parity when I configured them for both.

Performance isn't all that bad with parity as long as you have a UPS and "tell" Windows 10 that the storage space is power protected.

e.g. use the following command:

Set-StoragePool -FriendlyName Backup -IsPowerProtected $true

This makes a BIG difference in the write speeds :-)

You can, of course, use the parameter even if you don't have a UPS, but that's NOT something I'd recommend, as you could then lose a significant amount of data if you have a power outage while writing to the space.

Running two Antivirus' is never a good idea.

@garycase - thanks for that. I wasn't aware of that command. What sort of performance increases are we talking about and what's happening in the background to make it perform that much faster just because you've got power protection? I'm assuming it's some sort of write caching?

yse if powerprotected it is caching the data in ram

As David noted, it caches the data in RAM as long as it "knows" it can safely catch up because the system has power protection.   It makes writes SIGNIFCANTLY faster -- I saw more than a 3x improvement with the power protected parameter set to True.
