I don't question that HDDs are much cheaper - but even with your franken 40-drive stripping solution, you are only getting as much performance as 3 SSDs (40Gbps < 3 * 2.4GB/s).
Of course for video production you would choose slower, larger SSDs but still get an order of magnitude more performance, very handy when seeking through footage.
- Dylan16807 8y agoHow much performance do you actually need, though? As long as you can load 60 * k arbitrary frames per second then you can skip around at will. Being capped at the equivalent of 3 or 10 high-end SSDs isn't problem if there's no good way to fit more than that with any tech. And you don't exactly need to stripe them all. You could set it up as a blob storage, maybe storing each blob twice so you can distribute reads better.
