I am getting maximum of 32MB/s write speed on a USB 3.0 pendrive on Rock Pi 4 B. This pendrive gets on PC more write speed, up to 80MB/s. What should I do to make it work faster attached to Rock Pi 4 B?
Tried both “device” and “host” modes, no luck.
USB 3.0 pendrive
It seems the USB device is detected as USB 2.0 mode. You can try the lower USB3 port. Also, paste some dmesg log also helps.
Yes, I was using lower (closer to the board) port. And the same is when I boot up the Pi with pendrive inserted.

Anyone?
Getting anywhere on this? I’ve got an external usb 3.0 hard drive and my transfer speeds are only 25MB/sec. (About 50MB/sec reading)
What do you get from ‘lsusb -t’? With my hard drive connected, I show 5000, so I’d expect it to run at 3.0 speeds, but it doesn’t want to.
I’ve tried other pendrive and results are the same - no more than 30MB/s. The first one was GoodRam 64GB, second one was SanDisk Extreme Go USB 3.1 64GB.
@ditchmag I also have 5000 but pendrive acts as USB 2.0. Output below:
/: Bus 08.Port 1: Dev 1, Class=root_hub, Driver=xhci-hcd/1p, 5000M

Add to this list Transcend JetFlash 820G USB 3.0 and sata-usb3.0 reader AgeStar 3UBT2-silver. In lsusb -t they detected with 5000M, but speed is only 29-31 Mbit/s
And is everyone using Ubuntu server, or have they tried another OS with the same result? I’ve only used Ubuntu server so far. Really was looking forward to the usb 3.0 speed as my main use was for samaba server/OwnCloud server.
Edit:
As a comparison, I did a large file transfer with the usb drive connected to a windows machine and was able to to get 120MB/sec transfer speeds. This is on an x4 USB HDD enclosure, so I was reading from a 2tb drive and writing to a 3tb all over that one USB connection. I have a SanDisk extreme 3.0 pendrive I’ll test speeds on the rockpi4 next.
I tried only Ubuntu Server, since Debian is only Stretch (so it’s doesn’t have necessary libs versions that i need)
Ok, I connected my Sandisk extreme 3.0 32gb usb drive and mounted it using this command:
sudo mount -t vfat /dev/sde1 /mnt/32ex -o uid=1000,gid=1000,utf8,dmask=027,fmask=137
I then opened an ssh -X session and ran:
sudo nautilus
I then copied a large file from an ext4 formatted partition (mounted inside my USB hard drive enclosure) and pasted it on the Sandisk Extreme 3.0 usb pendrive. It was writing at about 100MB/sec! But then the system crashed for some reason before finishing, so I’m going to try again.
ntfs-3g is part of my problem with the ntfs formatted drives, but I expected the ext4 drives to be faster. At least vfat seems to work in this case, and obviously the read speed from the ext4 partition was reaching 100MB/sec as well.
EDIT:
Repeating the above steps it was successful moving a 2.7GB test file from the ext4 partition to the pendrive and maintained about 100MB/sec transfer rate. I then copied the test file from the pen drive to a sub-folder on the same drive and it transferred at a speed of only 35-40MB/sec.
EDIT:
Further testing:
I copied the test file from the Sandisk Extreme usb drive to the ext4 drive inside the USB hard drive enclosure and saw transfer speeds of about 55MB/sec.
Taking the same test file and copying from the ext4 hard drive to a subfolder on the same drive saw transfer speeds of 35-38MB/sec.
This command does not give any special abilities to the kernel to achieve such speed. There must be other reason why you managed to speed up the copying process. Maybe cache was used in your tests or Linux GUI has given some advanced control over the buses.
For me it should work out-of-the-box in console mode.
Yes, I don’t know how it achieved it, but it shows it is possible. Interesting that it only transferred at those speeds under very certain conditions. Copying a file to and from the same drive still had abysmal speeds. I would really like to figure this issue out since it won’t work for me as a file server with the speed so slow.
I ran ‘sudo dmsg |grep usb’ and here is the output if this helps. It is showing xhci_hcd, so I think it should be ok there too, but maybe there is something else in there I’m not aware of:

Here are some interesting result running hdparm. This was run on my 2tb ext4 formatted partition inside my 4 bay usb 3.0 enclosure:
rock@RockSvr:/mnt/3tb/UbuntuBackupConfigs$ sudo hdparm -t /dev/sdb2
/dev/sdb2:
Timing buffered disk reads: 236 MB in 3.01 seconds = 78.36 MB/sec
rock@RockSvr:/mnt/3tb/UbuntuBackupConfigs$ sudo hdparm -t /dev/sdb2
/dev/sdb2:
Timing buffered disk reads: 256 MB in 3.01 seconds = 84.98 MB/sec
rock@RockSvr:/mnt/3tb/UbuntuBackupConfigs$ sudo hdparm -t /dev/sdb2
/dev/sdb2:
Timing buffered disk reads: 306 MB in 3.02 seconds = 101.47 MB/sec
rock@RockSvr:/mnt/3tb/UbuntuBackupConfigs$ sudo hdparm -t /dev/sdb2
/dev/sdb2:
Timing buffered disk reads: 246 MB in 3.02 seconds = 81.47 MB/sec
Additional runs on a 320GB drive and 250GB drive inside the same enclousure:
rock@RockSvr:/mnt/3tb/UbuntuBackupConfigs$ sudo hdparm -t /dev/sdc1
/dev/sdc1:
Timing buffered disk reads: 296 MB in 3.01 seconds = 98.41 MB/sec
rock@RockSvr:/mnt/3tb/UbuntuBackupConfigs$ sudo hdparm -t /dev/sdc1
/dev/sdc1:
Timing buffered disk reads: 302 MB in 3.01 seconds = 100.44 MB/sec
rock@RockSvr:/mnt/3tb/UbuntuBackupConfigs$ sudo hdparm -t /dev/sdd1
/dev/sdd1:
Timing buffered disk reads: 272 MB in 3.02 seconds = 90.10 MB/sec
rock@RockSvr:/mnt/3tb/UbuntuBackupConfigs$ sudo hdparm -t /dev/sdd1
/dev/sdd1:
Timing buffered disk reads: 246 MB in 3.02 seconds = 81.55 MB/sec
However, actually copying any files and doing anything real results in terrible speeds.
EDIT:
Additional testing using dd:

EDIT:
Another test. I created an image of my 320gb drive and stored it on my 2tb. The speed was slow.

Do you know the usb chip of your drive? I think it’s some model from Jmicron? Does it support UAS?
I just noticed that UAS module should be automatically loaded. If not, please run:
sudo modprobe uas
and make sure lsmod shows it.
Here is my output of lsusb -v that pertains to the enclosure. It looks like a JMS567. I was able to reach decent speeds using dd as well. Could you try transferring a large file on your device using ‘rsync – progress’? I’m curious what a real world transfer speed would be for you. I had the same result with slow speeds when connecting my SanDisk extreme 3.0 is drive. This model:
