When I do something like: dd if='fedora.iso' of=/dev/sdb status=progress I only get around 6 megabytes per second on a USB 2 Sandisk Cruzer Blade flashdrive (store bought, not fleabay) plugged directly into a motherboard's USB 3 port - one that's not sharing its host with any other ports in use. Surely it should be going a lot faster? When plugged in, dmesg shows this for the drive: [337595.365826] usb 1-4: new high-speed USB device number 24 using xhci_hcd [337595.489415] usb 1-4: New USB device found, idVendor=0781, idProduct=5567, bcdDevice= 1.00 [337595.489426] usb 1-4: New USB device strings: Mfr=1, Product=2, SerialNumber=3 [337595.489433] usb 1-4: Product: Cruzer Blade [337595.489439] usb 1-4: Manufacturer: SanDisk [337595.489445] usb 1-4: SerialNumber: 00007014102520061826 [337595.557718] usb-storage 1-4:1.0: USB Mass Storage device detected [337595.557933] scsi host6: usb-storage 1-4:1.0 [337595.557995] usbcore: registered new interface driver usb-storage [337595.560673] usbcore: registered new interface driver uas [337596.561807] scsi 6:0:0:0: Direct-Access SanDisk Cruzer Blade 1.00 PQ: 0 ANSI: 6 [337596.562686] sd 6:0:0:0: Attached scsi generic sg2 type 0 [337596.563276] sd 6:0:0:0: [sdb] 60088320 512-byte logical blocks: (30.7 GB/28.6 GiB) [337596.564047] sd 6:0:0:0: [sdb] Write Protect is off [337596.564057] sd 6:0:0:0: [sdb] Mode Sense: 43 00 00 00 [337596.564305] sd 6:0:0:0: [sdb] Write cache: disabled, read cache: enabled, doesn't support DPO or FUA [337596.584964] sdb: sdb1 [337596.586991] sd 6:0:0:0: [sdb] Attached SCSI removable disk [337609.674186] usb 1-11: USB disconnect, device number 19 -- uname -rsvp Linux 3.10.0-1160.15.2.el7.x86_64 #1 SMP Wed Feb 3 15:06:38 UTC 2021 x86_64 Boilerplate: All unexpected mail to my mailbox is automatically deleted.
