I was careful to say I was testing write speed, but thanks for drawing further attention to it. My specific need is to copy large files quickly to a pendrive so I don't much care about improving read speed. > Didn't seem to do much for write speed on a USB connected hard drive, > so the significant benefit seems limited to write to flash. That's > important, but for many uses there are far more reads than writes. Same here. I did try it on my external USB hard drive (Iomega 500GB) but I don't notice the effect. This could be because of Flash limitations in the pendrive, but perhaps also because the hard drive has a better processor (USB is basically a specialized packet protocol and requires a cpu -- or at least a state machine -- at each end.) > HINT:I wish it were a standard feature of install to a flash drive. > Manually setting it during install is probably worth trying. Any FC11 > developers reading this? HINT!! Good idea. It also couldn't hurt when the system is *running* from a Live USB stick with a persistent overlay. poc -- fedora-list mailing list fedora-list@xxxxxxxxxx To unsubscribe: https://www.redhat.com/mailman/listinfo/fedora-list Guidelines: http://fedoraproject.org/wiki/Communicate/MailingListGuidelines
