I have to ask.......If you are concerned with file size and speed.....why on earth are you using the TIFF format?? PSDs are smaller file and they ARE the native format for PS.
I'd be curious to hear what others have to say as from what I've read, 16 bit TIFF is preferred over PSD...
Jeff Schewe commented on TIFF vs. PSD
Wrong...PSD is now a bastardized file format that is NOT a good idea to use. Even the Photoshop engineers will tell you that PSD is no longer the Photoshop "native" file format. It has no advantages and many disadvantages over TIFF.
TIFF is publicly documented, PSD is not. That makes TIFF a preferred file format for the long term conservation of digital files.
TIFF uses ZIP compression for max compression, PSD uses RLE which if you save without the Max compatibility will be a bit smaller, but at the risk of not being able to be used by apps, like Lightroom.
TIFF can save EVERYTHING a PSD can save including layers, paths, channels, transparency, annotations and can go up to 4 GIGS in file size. TIFF can save all the color spaces PSD can. The ONLY thing I can think of that PSD can save that currently TIFF can't save is if you Save out of Camera Raw a cropped PSD, you can uncrop the PSD in Photoshop CS, CS2 or 3. That's one tiny obscure thing that PSD can do that TIFF currently doesn't. How many people even knew that let alone use it?
PSD used to be the preferred file format back before Adobe bastardized it for the Creative Suite. The moment that happened, PSD ceased to be a Photoshop "native" file format. PSB is the new Photoshop "native" file format for images beyond 30,000 pixels. And , at the moment, only Photoshop can open a PSB.
Getting back to the fist point, Adobe can do anything including stopping support for PSD because it's a proprietary file format. TIFF is public, even if it's owned by Adobe (by virtue of the Aldus purchase). Even if Adobe went belly up tomorrow, TIFF would continue.
And, let me be blunt, anybody who thinks PSD is "better" than TIFF is ignorant of the facts. If Adobe would let them, the Photoshop engineers would tell you to quit using PSD. Lightroom for the first beta did NOT support PSD and Hamburg fought tooth and nail to prevent having to accept PSD. He blinked, but you still can't import a PSD without Max compat enabled-which basically makes it a TIFF with a PSD extension.
I love it when amateurs deem themselves experts, especially when they reference Luminous Landscape as a source. We can thank the internet I suppose. I'll bet you "expose to the right" and still think that a crop sensor makes your lenses longer too.
BTW. Schewe has omitted two very important aspects about PSDs. Are you expert enough to know yourself?

Is there a specific reason why you respond this way? Rude, offensive, immature, etc ....

Indeed, very rude and not constructive. If I thought I were the expert on this topic why then would I have started this post asking for support in the first place ? Why are you even on this forum Mr. expert ?
How immature of you. As you said yourself in one of your posts, just because you are a fan of great photographers doesn't mean YOU have talent. Is that the theme of your autobiography ?
Your profile says "Secret Sensei" and I guess (at least I hope so) because of the quotes it's meant cynical. AFAIK a Sensei never calls him/her selves like that, it's a title they get from their students and/or is gained by doing something extraordinary. If it's not meant cynical I'm curious what you did to deserve such a title or (looking at your behaviour/attitude) is it a self proclaimed title......
