This is normal with SMR disks. They have buffer for a short write, but if the data doesn't fit, it fills up and the drive slows down so it can remap the data from the cache to the shingled zones. Some bigger (than 4TB) SMR disks have better management of SMR or just more platters so the speed does not drop lower than 10-15 MB/s
Sorry, there was a problem. Please try again later.The 5 gb. speed is the theoretical transfer speed of usb 3. This speed is affected by all kinds of things like speed and types of drives being used, cable's, probably ram speed, the program being used to do the transfer and many other things. Because there is so many things that can affect the transfer rate only under ideal conditions will anyone ever see 5 gb speeds. Having said that you should see better than 5 mb speed. Maybe trying a different cable or a different usb port could help or go to the Dell support site and look to see if there are driver or bios updates for your specific computer.
