Hi,
having read the great hardware recommendation guide and some more forum posts, I am a bit stumped with my requirements: I want to store video camera recordings of a festival with multiple simultaneous tracks (concerts, discussions etc.). The cameras record to SSDs, and after each event the SSDs are moved from the camera to a workstation which copies the files to a NAS, then the SSDs are formatted to be used again. Each camera produces 90 GB/hour, and to get all the content copied to a NAS we need a sustained write rate of around 300 MB/s (well, at least for 30 minutes). Total required storage size is around 50 TB effective. I'm not looking for good IOPS. Read speed during heavy write is not important.
Looking at the performance numbers for large SATA drives (e.g. WD Red 10 TB), I'll probably have to write to at least 4 of them in parallel to get close to my required write rate. An all-flash solution would work, but I've seen the price and it's not really an option.
What I'm looking at: (feel free to point out any stupid mistakes)

- FreeNAS 2U certified server, Dual 10 GbE, 12 bays of WD Red 10 TB, running with RAID Z2
- TrueNAS X10, Dual 10 GbE, Raid Z2, probably dual power supplies
- DIY build (but AFAICS that rules out buying support from ixSystems, so not really a good option)
