I bought a Nab9 i9 12900HK mini PC to run the following software properly: Blue Iris, VMware Workstation 17 Pro, Synology DSM 7.2, Plex Server and WireGuard VPN server. Instead of investing in an NVR, I chose this option to manage six IP cameras with resolutions ranging from 8 to 12 megapixels. Do you have any suggestions, tricks, tweaks etc? Cost CD$700 for mini pc+ existing external m.2 SSDs via usb 3.0 enclosure & 1 internal 4tb ssd.

Review: MINISFORUM Venus NAB9 Core i9-12900HK Mini PC

This Venus series mini-PC incorporates an Intel Core i9-12900HK processor with a peak clock speed of 5.0 GHz, making it proficient for office tasks and even moderate video editing operations. Armed with 32 GB of RAM, a 1TB NVMe SSD, and running on Windows 11 Professional the device is a very...

Mini PC and external SSDs via USB is a recipe for disaster.

You could have picked up a used SFF from ebay for a fraction of the price and be better off.
 
Some need to learn the hard way, like chasing MP lol....

Just keep in mind many people try this route and then come here with problems. It isn't until an exhaustive list of questions is it revealed it is a mini-PC.

Mini-PCs are not designed for 24/7 operation, cooling is poor to non-existent, the CPU is designed to favor temperature control over performance, 2.5" HDD have been shown to be problematic with recording 24/7 video, USB cannot keep up, etc... the list goes on and on....

The theoretical transfer speed of USB 3.0 is 4.8 Gbit/s (600MBps) and when I tested it with 2 cameras for the live recording, it started stalling after 25min. It can't keep up with the sustained, non-buffering of video cameras.

Theoretical and real-world and sustained are totally different numbers.

It can even struggle with moving already recorded video over.

So here is a real-world demonstration. I was trying to move roughly 260GB of data from NEW to STORED.

I was moving it from a WD Purple (750 MBps) through a USB 3.0 (625MBps) port to another WD Purple HDD (750MBps)

At first it said it would take about 2 hours to move 260GB, but look how fast it dropped to a transfer of 37.7MB/s

Two hours came and went. About 6 hours later, the speed had dropped to less than 2 MB/s.

260 GB (260,000 MB) should have taken 416 seconds or less than 7 minutes at the theoretical speeds.

Those speeds just are not going to cut it for live recording of non buffering video.

Some say they work just fine, but I suspect they simply haven't had an incident happen yet where they found out they are missing recordings.

Not 24/7, only motion detection recording and that only on internal 4tb ssd. Externals for media server Plex etc. one Ethernet port directly to the poe switch and second to the router.
