Las Vegas (NV) - USB 3.0 may promise data transfer speeds of up to 5000 Mb/s (625 MB/s) but such levels will not be possible, at least not in initial devices. When USB 3.0 hardware will become available in late 2009 or early 2010, users will have to settle for about one fourth of the theoretical maximum bandwidth, TG Daily learned.




Sigh



USB is such a low rent technology. I'm glad to have it but I still see need for higher end connectivity that delivers a high % of its theoretical bandwidth

    How much cpu power for that speed?

    Was the limit there imposed by the connection or the drive though?



    They should have tested it with a RAID system possibly SSD as they mentioned.



    As they point out, it should be fast enough for most peripherals. 125MB/s is a decent write speed. No more than eSATA but the good thing about USB3 is being high performance and standard for lots of peripherals.

    Those read and write speeds- 165MB/s and 125MB/s -are pushing it for any mechanical hard drive. In fact, that's faster than a VelociRaptor except for burst (cache) read.

    The new USB 3.0 protocol is good. The only thing we need is good controller chip.

    Canon agrees with you and that's probably a reason all their Professional Camcorders are Firewire:

    Um...aren't all of those HDV cams? Then yeah...FW.



    Shame...all 3CCD ones too. WTF? No CMOS based Red killer? Canon video arm is seriously stuck in the mud. Their camera division should give them a big kick in the pants and build a real vid cam based on the 5D Mk II sensor.

    I couldn't agree with you more. But I think a 5D style video camera is targeted at professionals and semi-pros more than consumers. I don't think CES is the appropriate to announce a camera like that. I am, however, crossing my fingers for a NAB announcement.



    Canon, theoretically, is the only big camera company with all the components at their disposal to build a RED challenger. They've got the chip foundries building big chips for their DSLR's. They've got their video engineering team. They've got an amazing lens manufacturing plant. They just need the will to do it. And therein lies the potential problem. Canon is usually tepid about taking big risks.



    Not to derail this thread any further, but I want a 5D sensor with a lens mount that can take advantage of all their lenses, mated with a proper video backend with full controls, 1080p or 2K resolution, 10-bit, RGB, and solid-state recording.

    That is if the FireWire community can deliver a chip that is as good as the current controller chip from TI. This is a poor showing for USB 3 but I don't expect the bad performance forever.



    In any event niether USB 3 nor eSATA really strike me as the interfaces for the high speed storage devices of the near future. If flash storage systems can already do more than 700 MB/second niether of these interfaces has a long term future. At least with FireWire one ends up with a more flexible interface.
