Bot PCI and PCI-e are slightly lower latency than either FW or USB. The CPU load and overall latency are very close over all.
The main benefit you would be getting with the HDSP series hardware is the flexible expansion You can mix and max up to 3 HDSP cards in your system for a huge amount of I/O expansion. The Fireface series with most systems is limited to 2 units connected to the computer.
The USB based Fireface devices like the UC, Babyface and UFX all work great on either PC or MAC. ON the PC side. Firewire is starting to become less common of a built-in feature on motherboards and especially laptops. USB 2 and now USB 3.0 are becoming more prominent.
Unless you are really planning on adding allot of I/O as in more than 32 channels of I/O then you will be fine with the Fireface series.<<<<<<<<<

Its been a few years since that quote, but now I am at a similar crossroads.

I'm upgrading a very PCI+multiface (0 complaints for the last 10+ years), for a new computer. i admit I haven't paid much attention over that period , because i didn't need to ) So I figured I'd go for the PCIe card. And as long as I'm at it, a MultifaceII.

is MultifaceII history now?

I don't really need the preamps, so what's the most stable and lowest latency way to go? Is USB 2 really that good? Better than firewire 800?

I see there's a FF802 and a UFX - there's not a huge differentiation in features and price. Whats the deal?

Cool looking at the MR816X...

I need an SPDIF i/o on my computer to hook up to a Crane Song Hedd 192... I need to slave the SPDIF i/o to the master clock... would the MR816X be able to do this? It sure looks like it? Slave to a clock for the SPDIF i/o?

Is there any benefit to something more expensive like the FireFace if you don't need the preamps? Any other boxes you guys recommend?

If you can get a used FF400 for a good price otherwise UC.

Got an Apollo Twin recently and it doesn't hold a candle to my FF400.
RME even updated the Totalmix app for it even though they no longer make it, thats product support.
