USB performance issues - 1.4.2.beta2?

I´m trying the 1.4.2beta2 on a Dell Wyse 5070 (Intel Celeron J4105) and HDD connected on USB3. I´m getting constant speed around 13 Mb/s with large files on different drives while the possible speed should be around 90 Mb/s. It´s the same speed with the new backup-app and also while copying on the files-app.

Does others have the same problem?
What speed get you with usb-connected drives?
What could be the reason - not recognized hardware on the Wyse? Missing drivers on ZimaOS?
What or how can i check on ssh-console?

Thanks for any help!

I´ve tried this with ZimaOS 1.4.4-beta1 and i get the same (slow) speed. But connection is 5Gbit/s and the disk worked faster on same port under a live linux from stick.
Here is a picture from the usb-connection:

Thanks for your info.

If convenient, how will you fill in this table? (pics are better, and videos are best)

Look forward to your feedback.

Thanks for your regard!

First in text, pictures are attached :

Speed on ZimaOS: 13,3 Mb/s in “Files” and 12,92 Mb/s on console.
Speed on CachyOS: 64,3 Mb/s in “Dolphin”, was unable to get speed on console on live system
(Speed of this HDD at USB3 on Win10 was around 90 Mb/s - this is near the theoretical 100 Mb/s. But 60 is 4 times faster then 13 - and 13 Mb/s seems to be only usb2-speed.)

Also attached is a file with hardwarelisting (between).

Thanks for your feedback.

Thanks for your info. Please attach here the specs of your machine and USB accessory(including possible hub/adapter).

Thanks for your regard.

In between the pictures above is a txt-file with the hardwarespecs (“anon” because without serials). But i attach it again.

It´s a Dell Wyse 5070 with Intel Celeron J4105, 8 Gb of RAM, an 1 Gb SATA-SSD (Intenso) and a
USB-enclosure Hiyatek HY-EB-2508-U3 with JMicron JMS566 SATA 3Gb/s bridge with a
Seagate ST1000LM014-1EJ164 SSHD.
(Btw. the disk is fully recognized and can be mounted by ZimaOS in this enclosure.)

If you look in the txt-file, you will find the connection and more information, if you search for “jmicron”.

Thanks for your work.

Hey, to address you issue, could you recall the File system you used in your USB drive?

Thanks for your reply!

It´s NTFS.
