unRAID
Reddit take
AI summary of the Reddit excerpts below — not a quote
unRAID is a popular NAS operating system favored by the homelab and data hoarding communities for its extreme flexibility with hardware and power efficiency. Users frequently highlight its ability to mix and match hard drive sizes and its feature that spins down idle disks to reduce electricity costs. While it is widely praised for its ease of use in media server setups (like Plex) and automation, recent sentiment is tempered by concerns over changes to its pricing model and a shift toward subscription-based licensing.
Pros
- Supports mixing and matching hard drives of different sizes and brands
- Power-efficient drive management through the ability to spin down idle disks
- Runs directly from a USB flash drive, leaving internal SATA ports free for storage
- Includes a 'preclear' utility for testing new disks and adding them without parity rebuilds
- Fast boot times and straightforward setup for Docker containers and automation
Cons
- Paid software with a perceived trend toward higher prices and subscription models
- May be too resource-intensive for very low-power ARM devices with limited RAM
- Occasional hardware compatibility issues with specific expansion cards
Caveats
- The software is moving away from its traditional one-time purchase model toward tiered or subscription pricing
- Relies on a USB boot device, which can be a single point of failure if not backed up
- While flexible, it is often compared to TrueNAS/ZFS which may offer different performance or data integrity profiles depending on the use case
Best for
- Media hoarders and Plex server enthusiasts
- Users who want to expand their storage incrementally with mismatched drives
- Home lab users prioritizing power savings and ease of use
Avoid if
- You require a strictly free or open-source NAS operating system
- You are running on extremely minimal hardware, such as low-RAM ARM boards

Bro please get something like unraid setup for this, this hurts me
Unraid sounds really intriguing and potentially ideal for my uses.
I am a media hoarder (142 TB raw Unraid server) if I'm a hoarder.
However you typically trade the flexibility of something like truenas or unraid for whatever the devices OS allows you to do.
I am very happy with the automation setup I have and my main workflow is browsing Letterboxd and learning about movies while and adding those movies to lists which then download
You need a DIY NAS running something like unraid or trunas.
Which leaves Unraid and MS's Storage Spaces. Unraid costs between 50 USD (for only six drives) to 250 USD for unlimited drives and lifetime updates. ... Both Unraid and Storage Spaces will elegantly let you use drives of different sizes
Unraid boots under 5 min and everything is up and running.
I ran unRAID for years, loved it
Unraid is perfect for them since it can spin down the idle drives.
