No question it’s fastest way to do for very heavy I/O. But you need money to burn – FusionIFX is going to run you $1500 to $2000 for 480GB vs. $400 (or in my
case I got two Crucial 480’s for $270 each). A RAID 0 SSD will be nearly as fast and in my experience you are rarely running a RAM preview in AE and doing something else I/O heavy at the same time, so that saturation won’t happen in AE that often.
Hopefully SSD PCIe storage will come down in price as SSD’s have. Hopefully the new MacPro will prompt more of it – although Thunderbolt has been slow to come
down in price. But I think PCIe has a brighter future since it can be implemented cheaply in volume.

A film is – or should be – more like music than like fiction. It should be a progression of moods and feelings. The theme, what’s behind the emotion, the
meaning, all that comes later.

Get the an SSD dedicate to AE cache – you will want 256 to 500 GB for decent fast cache for 4K previews. Even a 1TB would not be overkill if your master is over 4K.
And you might consider PCIe-attached solid state storage for the cache instead of a SATA SSD. It's startingly easy to saturate the SATA bus with any combination of large rasters, higher bit depths, and lots of layers.
A single 19,200 x 8640 buffer at only 8bpc is 632 MB -- or two second's worth of bandwidth for SATA 3Gb/s, or one second's worth of bandwidth on SATA 6Gb/s. You could cut that in half again or better with PCIe flash storage like the Fusion
ioFX.
