And if you have multiples of those tons of cash, go up to 504 GB worth
of DRAM storage, connected by external PCI Express.  It claims 3
microseconds (0.003 ms) seek time, which is more than the HyperDrive
above, however at 1/2 Terabyte, there's an obvious size advantage.

Imagine throwing this on an Oracle box and putting the redo logs on it.

It also can use Flash memory which nets you 5 TB of storage but at flash
memory speeds.  It does not seem to have any kind of battery backup.
