When I see something like this, which itself is deeply disturbing, I become even more concerned about the holes in our infrastructure about which we know nothing.
It’s not what you know that is important, nor is it what you know you don’t know. It is those things that we don’t know that we don’t know that will bite us in the collective keister.

The economics of flash memory are staggering. If you’re not using SSD, you are doing it wrong.
Not quite true, but close. Some small applications fit entirely in memory – less than 100GB – great for in-memory solutions. There’s a place for rotational drives (HDD) in massive streaming analytics and petabytes of data. But for the vast space between, flash has become the only sensible option.
If you have a dataset under 10TB, and you’re still using rotational drives, you’re doing it wrong. The new low cost of flash makes rotational drives useful only for the lightest of workloads.
These are very bold statements. I agree with them.
Switch your databases to Flash storage. Now. Or you’re doing it wrong.
