I answered your question in one of the other threads where you posted it under my correct answer from a few weeks ago.Hello I just cloned my hard drive on my 21.5 late 2014 iMac (Mojave) to a T5 from Samsung (1tb) using super duper. When i reboot and hold option i can select the SSD, however once booted its amazing but once i restart it defaults back to the HDD. I looked in startup disk and it wasn't listed only the HDD was any thoughts on how to fix this?
Well, Apple isn't going to recommend CCC!Apple recommends Migration Assistant. It works just fine without the potential for problems that cloning software can cause.
The main reason I like cloned drives is because I like to have a spare drive(s) that I can use to boot up in for trouble shooting, or for accessing old software that I can no longer use. The Disk Utility GUI on older MacOS comes to mind, having more options such as creating software RAIDs.So this begs the question, what are the problems CCC and MA each create?
I don't think this is true. Maybe I am not understanding what you posted, but the Fusion Drive will only function at SSD speed if the data is on the SSD part of the Fusion Drive.
Welll, that's only true up to the capacity of the SSD portion. My iMac has a 1TB Fusion Drive with 128GB of that being SSD -- it's generally super fast as you say but if you launch or bring up some big file you haven't been working with for a long time, you can tell the difference as it gets migrated to the SSD.
This is my experience as well with the 27" Late 2012 iMac with the 1TB Fusion Drive.it's generally super fast as you say but if you launch or bring up some big file you haven't been working with for a long time, you can tell the difference as it gets migrated to the SSD.
This is correct, except I am pretty sure the lowest was 24GB of SSD, which was the late 2015 models, then they were increased to 32GB for the 2017 Fusion Drives.Also, some of the Fusion Drives out there have pretty miserly alotments of flash memory, which sort of blows. As little as 32 GB, if I'm not mistaken...
I mean, I guess this is just confirmation that the Fusion system is working as it should! People around these forums crap on Fusion Drives a lot, but honestly I think that as long as the SSD part is big (and you have to get a 2TB one these days to get a good-sized SSD portion) it's very much the best of both worlds -- especially since Apple charges such nosebleed prices for SSDs in new Macs.When I was playing on a regular basis, the load screens would only last a few seconds. After taking a break for a month, the load screens would take much longer to load. I just recently started playing again, the first week of load screens were very slow, but now they are much faster, only a few seconds.
Replacing the OEM 128GB Nvme blade with 500gb Samsung 970 EVO and removing the hard drive. Current R/W speed is about 2100/700 MB/s and hoping to get somewhere near R/W 3000/2000 MB/s speeds.
