Hey all,
I'm running:
OS: MacOS Mojave 10.14.5
Computer: Macbook Pro 15" 2017
And I have recently purchased the following for use as a backup device:
I tried many times to use Time Machine as a backup solution, but it always:
- stalled and became unresponsive at different intervals of the backup procedure (between 30-200 GB)
- locked up / crashed finder, even in safe mode.
I then moved to Carbon Copy Cloner hoping that this was a bug / incompatibility with TimeMachine. Unfortunately the problem persisted.
Finally, I wondered if this could be heat related. I know NVMe SSDs run really hot under heavy load, but I thought this wouldn't be an issue because:
1.) It is reported that these devices only thermal throttle after ~800GB continuous writing.
2.) This enclosure being USB 3.1, I would only be able to write below half of full speed anyway.
3.) Thermal throttling is just a safety measure that lowers performance, not something that renders the device inoperable.
4.) The enclosure has a heatsink on it, which should help the SSD further in this regard.
Well. As it turns out, that's none of that seems to have held true.
After about a dozen failed attempts with Time Machine and Carbon Copy Cloner, I decided to try to do the backup with the heat sink laying down against a frozen gel brick
And... wouldn't you know it, the backup completed successfully, with All 750GBs having been copied in 55 minutes.
Now I'm wondering if this could be because of:
A.) A defective enclosure
B.) A defective SSD
C.) An incompatibility in regards to my intended purposes.
What are your thoughts and recommendations in regards to this issue?
Thank you.
