Lacie launches the 12big desktop Thunderbolt 3 RAID storage unit

Apples to apples. We're still talking about raid here? Queue depth, stripe size, alignment and all those things you don't have to worry about when you're doing sequential bursts of data to a single s-ata disk?

And no, 280Mb/s is not real life performance from a 7.2K drive, nearline or not.

Now, if we're discussing performance only, it means you're using JBOD or raid0. No redundance and backing up 24Tb (for the sake of real life usage, half the smallest size) it's still a challenge. If you want redundancy the lowest you can go without bending over performance is raid10. Which means a stripe of 6 mirrors. Which offers 36Tb for 6Tb drives and god forbid a full mirror should fail 6 drive redundancy with.... drum roll... 2.4Gb/s speeds considering a 200Mb/s real life performance, in raid, drive speeds.

Now, what I've said has a lot of stars if I were to market this rollbox on a panel in public view. But I guess that online it's ok.

Please bare in mind that I didn't took the time to check the price on this joke. I don't amuse myself with this kind of peasant storage hype by some lunatic company that feels they discovered premium tap water.

I will also jump in the band wagon of reasonable people and say concurrent access is a must for the pricetag of only the drives alone.

I'm with you that this is not an impressive product, but they were quite specific in the use case. They said this is ideal for video editing, and moving files that large is easy and it is one case where I would expect to hit the headline speed of the drives. Try compiling code off the array, and yes I expect performance to drop off a cliff.

The scary bit was the performance drop going from raid 5 to 6, so I guess they need more grunt in their block engine.

Only if you are on the cheap. Grown up systems expect raid 6, you still get plenty of spindles to read from concurrently so you should get plenty of performance. In this case performance should be a magnitude better than a single disk if you do 10+2.
