> My understanding from the video is that it's a write-once solution, If you have enough capacity, write-once is enough. Indeed, MLC SSDs can often be rewritten a couple hundred times. Consumer HDDs are specified for 180TB written per year. Would you rather have: * A HDD that can store 22TB and can be written 180TB per year for 5 years until the helium leaks out (900TB total writes). * A 10,000 TB storage cartridge that can initially store 10,000TB, but as you "erase" stuff the capacity falls. The latter can tolerate 1,000 TB "erased" per year for 5 years and still store 5,000TB at the end.
