Spot on, and at least for uncompressed video the old saying was it's all
about how much one can process, not how fast. Especially true for 2K,
4K and 8K film. Years ago it wasn't possible to get reliable high-speed
I/O on PCs, but that's changed, though consumer builds do of course lack
ECC protection which is a concern for pro users. Multi-socket XEON systems
tend to have this anyway so it's not a problem, but they're costly and
generally can't be overclocked. It's something I'm looking into atm, eg.
oc'd 990X or SB-E vs. dual-socket i7 XEON (main advantage of XEON systems
is the much higher RAM capacity - my Dell can take well over 100GB).

Top-end systems are often turnkey solutions supply ready to go, optimised
for the application, not really general purpose at all. Discreet systems
are like this.

I have a range of systems, couple of Avid SGIs (O2, Octane2) and several
original Discreet systems (quad-1GHz Tezro with Flame/Smoke and aual-600
Octane2 with Flame, each with 24 x 146GB 15K SCSI; O2 Effect with 22 x
73GB 10K FC) all with HD/SD digvid options, breakout boxes, etc., a
couple of SGI for hardware-capture/playback (customised O2, Octane2 V12
with Cosmo2 board, both for reilable JPEG) and some other high-end
systems aswell (quad-500MHz Onyx2 IR4, 36-CPU Onyx3800 IR4, HD digvid,
72GB RAM, not really setup yet though). I have some Adobe Premiere
systems but don't really use them.
PC-wise I have several systems, some for benchmarking research: i7 875K
(overclock not yet sorted out), dual-XEON X5570 Dell T7500 with Quadro FX
5500 (might switch to a Quado 600 I've just obtained if it's better), an
Asrock X58 Extreme6 with another X5570 (should oc like crazy), and a 990X
not yet set up. A mix of FC, SCSI, SAS and SATA storage. All the other
systems are more for 3D/CPU benchmarking (two i7 870s, i3 550, i5 760
[though this will be away on loan for a while], i5 760, and a range of
AMD builds, mix of mbds, range of GPUs).
Combining SGI/PC hw in an optimised manner is my current focus, but I'm
also doing a lot of PC benchmarking.

I did test an SSD with Flame, no observable benefit for colour correction,
but the bottlenecks on a PC platform could be very different. Hard to say.
What you could do is run Process Explorer to see what I/O is occuring
while running your app.
