My original post asked the question as to why I was getting different transfer rates using the above setup when copying to an ext4 formatted partition on that external Seagate compared to when doing so to a ntfs formatted partition. I provided the transfer rates as displayed in mc when using mc to do the copying.
I haven't even attempted to use Dolphin to do any copying because past exeprience has shown me that it's quicker to transfer a large file using the old morse code dots and dashes than use Dolphin :-) .
Earlier today, using the exactly the same setup and without any changes of any description, I copied a 7.1GB file to the ntfs formatted partition and this took around 4 minutes to do the copying versus last night's effort using mc which took around 15 minutes (actually, closer to 20 mins I think) to do a similar operation.
I just did some 'scientifically' based tests which showed that one must never rely on memory when providing details about what (may have) occurred :-) . I used a stopwatch to check how long it took to copy a file to (a) a partition formatted in ntfs on an external USB3 HDD and (b) how long to copy to the same HDD but to a partition formatted in ext4. I copied a 11.437GB file to the ntfs partition using 3 methods and the results were: 1. copy using cp command................. 4 min 59.1 sec 2. copy using mc................................ 6 min 29.3 sec 3. copy using Dolphin......................... 5 min 13 sec Then I copied the same file to the ext4 formatted partition and the results were: 1. using cp command....................... 2 min 17.3 sec 2. using mc...................................... 2 min 18.1 sec 3. using Dolphin............................... 2 min 18.2 sec
What is missing in my explanation of the situation to keep the issue of USB2 being brought up?
