I have a 2015 iMac 27". Can I use an external Thunderbolt 3 HD as a start up drive? I would have to get Apple's Thunderbolt 3 to Thunderbolt 2 adapter. And would I get Thunderbolt 2 speed or would it be slower with this set up?
I have to agree, I'm upgrading to a new iMac in the next few months (I'm in savings mode right now) and will configure the iMac with a 512 GB SSD and then use a OWC Thunderbay 4 Thunderbolt 3 in a RAID 5 configuration for most of my external storage. The SSD will just have Mac OS on it, my applications and data files that I access daily. The Thunderbay drive will have all of my large libraries such as all my video, photos and music libraries.
I will also keep 2 external USB 3 drives for my Time Machine and Bootable clone backups.
Yes! It will not be as fast as an SSD, but it will be as fast as starting up from the 7200rpm in your 27” iMac. It will not be as fast though, if your 27” has a Fusion Drive?
Just get or build yourself an external USB 3.0 SSD to use as a startup drive.
I need a lot more storage than I can get with a SSD. If I get get a USB 3.0 HD can I use it as a start up drive.
Thunderbolt 3 external drive as start up drive?
