You don't say what you are using and it makes a huge difference.im using an OWC enclosure with USB3 and would like to get a faster enclosure for an iMac Pro. Would a newer OWC enclosure with thunderbolt 3 result in much faster data transfer speeds? Is thunderbolt3 just usbc?
The only real difference is that it's loaded with Intel instead of Samsung. Although more expensive than the Samsung, the base model has 4 bays allowing you to expand by purchasing additional NVMe blades.The OWC Thunderblade v4 has nearly the same speeds as the internal iMac Pro drive. If you need speed and bandwidth of Thunderbolt 3, I recommend that option.
It probably is more a matter of whether you are exceeding the usb bus bandwith./ if not I wouldn't bother. If you feel the constraints, yes TB3 would offer more room and maybe better overall performance with less bottleneck concern. The trade off is cost.I currently have a OWC Thunderbay IV that is connected via USB3 and TB2. I think it is currently connected via USB3 and it is configured in JBOD mode. I use it to store photos and videos, and I need to edit in Lightroom, Photoshop, and Premiere. I'm wondering if the newer version with Thunderbolt3 will make a big difference with speed with what I'm doing?
I think I just overloaded my bus bandwidth...I had a small USB3 drive connected and was transferring gigs and gigs of files to a drive located in my Thunderbay Encosure. I also have a small USB 3 dock connected and I had a 7200 RPM bare bones drive in it that was using Carbon Copy Cloner to clone a drive that was also in the enclosure. As soon as I started cloning, the data transfer speeds from the small USB3 drive became very slow....By exceeding the USB bus bandwidth, do you mean at any given time pushing more data through the drive/cable to the iMac than it can support?
If so, what is that amount of the bus bandwidth limit?
I typically might copy lots of files from a small external USB 3 7200rpm drive to more than one drive inside of the enclosure, folders containing lots of images, files to another drive, and videos to another drive, simultaneously...this doesn't happen all the time, and I wouldn't have a clue as to how much data is being pushed at any given time.
