| 1202381 | 2011-05-16 08:46:00 | I would like a portable USB3 drive to test video files... Today I made a video file (Downton Abbey) removed the ads, put it on a USB stick, took it to the TV set to test it - and found that it needed a tweak to the audio delay. So it was back to the desktop. There it took VirtualDub less than a minute to render a new file. But to get it onto the USB stick was another 5 minutes! Plus I needed several versions on the stick to test different delays... A USB3 drive might have sped things up 10x - from 4MB/s to 40MB/s |

| 1202382 | 2011-05-16 08:57:00 | I think you just need a better drive! USB 2.0 can easily provide 40MB/s transfer rate (as it supports up to 60MB/s) The problem is most USB memory sticks can't actually write to the media that fast - however a real hard drive connected via USB could. |

| 1202383 | 2011-05-16 09:35:00 | I've just done a test with the file in question, putting it onto a WD Elements SE 500GB (USB2) . Win 7 peaked at 60MB/s but my watch showed 22 . 5MB/s . You could be right . That's a lot faster than my Lexar 4GB USB stick (which showed 4 - 5 MB/s in Win7 but I've never tested it with a watch) I like the idea of a USB3 HDD because I would treat it as a fast "USB stick" . I have more than a dozen drives but there's never one convenient whenever I want to test a video file or deliver a file to somebody . If I got a USB3 HDD I would put a 32 GB FAT32 partition at the start and that would be my "USB stick" forever after |

| 1202384 | 2011-05-16 10:52:00 | There are a few things that the USB transfer speed depends on: USB Controller chipset (some are better than others) Drivers Connected through a Hub or not Cable length\quality (If applicable) Storage device chipset\bridge performance Storage medium write speed (If a HDD, depends on RPM, seek time etc) Filesystem used Size and quantity of files written (multiple small files write slower than one file the same total size) Is the filesystem fragmented? Is it on a device which cares? (Flash vs HDD - access time issue) :waughh: |
