Thunderbolt 2 Drive Is Slow to Write
I'm running Monterey on a Mac Pro (Late 2013), 2.7 GHz 12-Core Intel Xeon E5, 48 GB 1866 MHz DDR3. This machine is still a rocket and I have no problems with its performance.
I have a myriad of external USB drives, both SSD and SATA. But I decided to put to use the four Thunderbolt 2 ports on the back and bought an OWC ThunderBay 4 mini Four-Bay External Drive Enclosure with Dual Thunderbolt 2 Ports. I added two WD SATA drives and started backing up files to them, with no problems.
But I've noticed that writing files to this drive bay is surprisingly slow, compared to my other USB drives. I work in Photoshop a lot and hit SAVE often, and yes, these are pretty good size files. But they take a lot longer than I'm used to.
What's up with that? I thought any version of Thunderbolt was faster than USB 3.0?
Thanks.
