hmmm
>What else would need such an extreme of SSD design?
need <> want, and I suspect that it's a want, which someone has disguised as a need as in 'we don't want the terry-wrists getting hold of this technology first!'.
sigh..

ViON have produced a 100TB DRAM solid state drive, which they claim to be the largest flash memory-based storage box in the world. The HyperStor-6200 uses both Hitachi Data Systems and Texas Memory Systems technology - think RamSan 6200 - and provides five million I/Os per second (IOPS) with 60GB/sec bandwidth. It is a monster …
It's a backup of there "Personal entertainment" cough cough :D 60GB/s Makes for perfect HD streaming if you ask me.
Or
Maybe this is the next step towards a better backup solution as tapes and ordinary HDD just dont provide the bandwith or storage required. With this i could backup my PC in just over 30 seconds
Memory stick that you carry in your bag = 8GB. 100 TB = 12800 of those.
Of course if you can build a big enough USB farm, park some ZFS on it and actually get some USB bus speed that can drive it, and you remember that you don't have any moving parts, you'r right, it is just not that cool.
RAID 1(+) mirrors so it protects against hardware failure.
Sure saying RAID protection can be misleading as RAID doesn't always involve mirroring.
And of course mirroring is not a complete backup solution, but it does offer protection, protection against hardware failure.
And of course it is wrong to say that RAID is just about availability, in fact more often it is about performance, whether striping on flash memory gives performance is probably worthy of investigation.
I unforget installing a 'ram disk' on Baker Perkins' IBM mainframe. It was the size of a couple of filing cabinets, and looked like a 10" removable platter disk drive to the OS, while being a hundred times faster.
It used about five horse-power's worth of electricity and contained something like 25Mb as I recall. Or would have done if the tight bastards had ordered it full.
At the time the streetlights outside were still gas-lit.
