Re: sure it's faster

"but at what cost?"

Why not do some digging and find out? You can read a dollar a gbyte:

If their effective capacity goes from 2.8 to 5 PB, that comes close to halving that $1/Gbyte.

"Don't doubt that for a minute for many workloads especially ones that fit in the cache."

They have DRAM for the hot data and up to 200 TB for warm data. Listen here if interested, it's mentioned:

How they promote and demote that is pretty involved and patents all around it. The 200 TB is just a copy of what lives on disk. And you can bet it isn't any coincidence that random talk about XPoint keeps showing up. It would be pretty slick to speed those warm cache hits up to much faster than 180 microseconds B^)
