Is anybody seeing numbers like this using ASIO with USB2?

I have a 10 year old Firewire 410 that still works well on my newest desktop with an add-on firewire card. My old laptop had a firewire port, but my new laptop only has USB2 & USB3.
So if I was going to get a USB2 audio interface, is there any chance could I get the same buffer setting to work on the laptop?
I get those exact numbers with both my Fractal Audio Systems rack unit interface and my Midas M-32 console interface. I have no issues running down that low even with a decent amount of tracks and VST's. Both are USB.

Wow, that's some serious hardware there! Good to know you can run that with USB2. I will now assume that it's not that USB that is the limiting factor, rather the quality of the drivers, and how they interact with the OS and hardware that determines the latency!
Thanks!
In my case, the USB stuff is working so well, it's actually scary. Just curious, but have you tried running a latency checking program?
http://www.thesycon.de/deu/latency_check.shtml Go there and download the tool. It's what the majority on this forum use to see if there are other issues. I have a friend that stays in the yellow and goes red quite a bit. He experiences clicks, pops and has other issues.
The thing the tool doesn't tell you, is what may be causing issues. The forum latency gurus will help you with that after you find out how your system responds to the test. I've never had one of my PC's fail because I disable everything that should not be running.
There is a site called blackviper.com (use at your own risk if you try it) that offers tweaks on every OS ever made. I've used his tweaks for optimizing my systems since Windows 95 with outstanding results. The only time I would say NOT to mess with these tweaks would be if you bought an actual audio computer from Jim Roseberry or someone that builds pro DAW's. They use their own tweaks for the parts they use and configure things to their specs. But any stock PC, I have always tweaked myself even if my tweaks are minimal.
One of the things I have found using SONAR for 100 years is, it's a little more needy than some of the other DAWs I use. Like in some situations, if you have too many running processes or programs, or dumb things that auto-load at boot that you are not going to be using while you record or you might not use them ever......they can definitely wreak havoc.
In other situations I've had great SONAR results with over 100 processes. It depends on the computer, motherboard, chipset in my personal experience.
Quick example, I have NEVER had luck with AMD. I've used the best Pentium I could afford and always had great results. I also have 3 drives as to not tax my system too much. One drive for my os, programs and plugs, one strictly for audio and streaming and a drive for samples only. I've used that format for years without failure. The only issue I have had with my computers is lightning taking one out. I have all the computers I have ever owned but 1, and they all still run and have some version of sonar on them.
RAM isn't even that important in my experience. I have 3 old machines running sonar from 512 ram to 4gig and they work great. Are they a little slow? Sure, but they work and never crap out. As a matter of fact, I'm using Asio4all on them and get down to the same numbers you mentioned in your post I originally quoted. I know that's hard to believe, but it's true. They aren't as fast as my real recording machines with i7's in them, but in a pinch they work and can bail me out. The one with the 512 ram is sitting on a shelf, but it still works great.
My point in all this is, once you get your machine set up right, you'll be amazed at what you can do even with slower computers. The drag of it all is, some of the issues we have, may affect SONAR.
I'm not saying that to turn you away, I'm just saying in *some* cases, sonar was more picky than other daws. If you exhaust everything and still have issues, go download reaper and try their trial version just to see if you have the same issues. If you do, you know it's going to be with everything. If you don't, something in your system isn't playing nice with SONAR quite possibly, or you may need to change something.
Whatever the case, the people on this forum will do whatever they can to help you as long as you listen to what they say. They really know what they are talking about. I'm a trial and error guy that doesn't know too much, but I've been really blessed with SONAR. Good luck!
