There’s a lesson to be learned here. Buy from trusted brands, not companies who sometimes make drives. Cheap controllers are not an option.
I buy from Caldigit and Promise. That’s all they do and they do it well. Heck, we have an old 12 drive Caldigit SAS system still running here, never had an issue, replaced all the drives 4 years ago, but only because we needed more space.
Drives also matter, we only buy Hitachi or Toshiba drives because their low failure rates blow the competition away.
I have 5 arrays running at the moment, all RAID 5. Never lost a single bit. 🙂

RAID 10 is fine as well, and even faster on the read side. But your storage takes a much bigger hit, so I would keep that in mind, especially on a 4 drive setup. (You lose 50% storage).

[greg janza] “I’d also discourage the use of Raid 5. There’s extensive info on the web indicating that Raid5 is problematic and should be abandoned. Since Raids are relatively cheap, I’d simply buy two, use raid 0 and mirror them.”
I have to disagree there. RAID 5 is perfectly fine at a 6 drive level, and most likely at 4 drives as well, unless you’re editing uncompressed 4K and absolutely need the speed. In that case, I imagine you can afford SSDs.
Unless you have an hourly spotless backup, RAID 0 is a ticking time bomb. Any of the drives failing will destroy the entire array. And I’ve seen my share of drive failures. The advantage is pretty clear, it allows one drive to fail, and trust me, they fail.
BTW, I’ve seen people crap on RAID 5 a few times. I’ve been editing on RAID 5 for 10+ years. It just works and saved me at least 3 times.
I’ll list the downside since it’s only fair. You lose the capacity of 1 drive and your write performance will be diminished, which doesn’t matter that much in editing.

Hi Andrew,
You definitely want all your footage on the RAID, and set your preview file path to the RAID as well.
The project itself can really be anywhere, that doesn’t matter.
Depending on the footage, you may not see a huge difference. Your bottleneck is likely on the CPU/Graphics card on a 2011 machine.

T2 is 20 Gbps/2500 MB/s. That’s about 4 times the array speed on our R6s so you should be fine 🙂

Promise Pegasus 24TB as RAID 5.
There are smaller versions, 12 TB and 18TB , but at 12 hours a week, that will fill up quickly.
Then use Chronosync to manage your scheduled backups.

You might just have to look at a dedicated switcher for screens. The unit you are using is deigned for streaming (It’s really a PC with input cards), not designed for live production with iMag.
Most basic switchers will usually give you about a frame of delay. Look at Sony , Panasonic or Ross if you are just switching cameras. Even a cheaper Roland mixer would do it.

Hi Neil,
I’ll start with the camera. The one you listed looks fine, although 4k is probably overkill at the moment for streaming and may be for quite a while.
If you want good audio, consider purchasing a mic. The better mics will come with an XLR input and you can connect them via a USB interface. A good cheaper option is the Blue Icicle. For the mic, you can either go with a wired Lav or a podcast type mic.Finally, get some lights. That will improve your image considerably and reduce noise.

On a PC/MAC? Do you have Thunderbolt?
If you do, the easiest is a Blackmagic mini recorder SDI/HDMI to thunderbolt. Other options go quite a bit higher in cost with USB3 converters, etc. WIFI would not be a good option id you need a quality image or something reliable.
If the cameras are more than 25′ away, you’ll probably need to convert to SDI.

The simplest would be a Teradek cube,.
For the cameras, you’ll need a switcher. On the cheap side, you could try the Roland V1HD, you’ll need HDMI to SDI converters for runs over 25′ to the cameras.
Livestream has their own streaming devices that are pretty easy to use as well.
