But something happens between 1.31TB and 3.5TB. The file systems are about the same speed for small amounts of data (<1.31TB). This means that the speed was slower from the beginning.Ĭopy entire 3.5TB with Paragon NTFS driver: approx.
Here, significantly less was copied than in the previous test with 1.31TB and in a significantly longer time. Up to this point, both file systems look about equally fast.ĪPFS 15 hours (stopped here) only 486GB on external hard drive Here is a small update of my further investigations What can I do to make the disk usable for a Windows PC?.The hard disk can also be written to with the Mac in 9 hours (Scenario 3). It is not due to the external hard drive or the additionally required adapter from USB-A to USB-C on the Mac. But it is possible to write to the same disk with the same cable and the same data under Windows significantly faster. The activity LED on the hard disk flashes continuously.ĮxFat may have its optimisations for SSDs. I format the external hard disk with the Mac and start the copying process. The activity LED on the hard disk flashes continuously. A significant part of the data is copied which makes the prediction of 9 to 10 hours seem realistic. The prognosis is 9 to 10 hours under Windows. The previous data is deleted (not reformatted). The activity LED on the hard disk also shows very long pauses. Only a relatively small amount of data was copied, so the remaining 9 days would probably have been needed. 6 hours of running time, another 9 days are assumed. I try to copy the data from the NAS to the external hard drive. I have formatted the external drive with the Mac as exFat. A Western Digital Elements 5TB as external hard drive.
I think I can refute the previous answers and am therefore still looking for an answer or solution. I have read questions here about exFat and its performance on the Mac.
