#QUICK DISK TEST MAC DRIVER#
The NTFS driver that comes with macOS is read-only, so a separate driver is necessary in order to get read/write access.
#QUICK DISK TEST MAC INSTALL#
Yet another alternative is to format the drive as NTFS, which is the native file system on Windows, and then install an NTFS for macOS driver on your Mac.

Note that the linked software is commercial and requires purchasing a license. If you like exFAT and primarily have smaller files, you might be able to make do with FAT32 which is natively supported by both operating systems.Īlternatively you could format the drive as APFS, which is the native file system on macOS, and then install an APFS for Windows driver on your Windows PC. In order to format the disk so it can be used with better performance on both your Windows PC and your Mac, you can try a different file system. It is open-source and can be downloaded for free. I doubt that it has better performance for. The reason it is slow is that the implementation is not as optimized as it could have been.Ī third party exFAT driver for macOS exists that you could try out. The tip with Paragon fits perfectly in my case. Since the tests are very time-consuming and it is quite difficult to time the copying, I would like to stop my tests at this point. 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
#QUICK DISK TEST MAC UPDATE#
Here is a small update of my further investigations
