Prores HQ is 220 Mbps or 100 GB/hour. A full project should fit inside a 2 TB drive.
Three streams of it is 660 Mbps or 82.5 MB/s. A consumer grade Hard drive at 7,200 rpm will give 100 MB/s, no sweat.
Now comes the big question: is your data on any project really big enough to warrant 2 TB of source material?
If not, then you’re better off with a 1 TB drive on each machine. If you want greater speed, then you can RAID 1 two SSD drives.
For your cache/temp/page drive, you can use a PCIe SSD or a couple of small 7,200 rpm drives in RAID 0 on each machine.
If yes, and you are doing heavy work with multiple reads and a few writes, then take a look at RAID 5/6, on a NAS.
What happened in school has nothing to do with the NAS architecture. NAS is fine. Here’s an example in RAID 1/5.
You’ll need a gigabit (1 Gbps) Ethernet network – it’s not a problem.
Just remember, RAID is not backup. You’ll still need to backup your files on separate drives, preferably off-site.
