[Guide] Avoid APFS conversion on High Sierra update or fresh install

[RehabMan]

I recall pikeralpha was concerned that 3rd party SSDs may not contain the firmware for error correction that a real Apple SSD has, and that APFS relies on this said error correction. Is this still something to worry about? I'm hesitant to update my Hack (I'd rather wait to upgrade to HS until APFS is safe rather than stay on HFS+ (APFS is the only reason for me to upgrade right now)). I'm telling my bro with a real Mac using an OWC to wait as well until I hear that slow data corruption won't be an issue...

All storage technologies can fail. It is why we use backup software. Right?

Please note that the most common cause of data loss is "user error".

Off-topic.
Open a separate thread with "Problem Reporting" files as per FAQ.

What are the pros and cons of HFS+ vs APFS. Why would I prefer one of the other?

Hello all at tonymacx86 !!!
Just to ask for some help.
I have started the update process from Sierra to High Sierra.
I have done all the mentioned steps (updated clover, kexts, the terminal process)
and everything was made with careful and following the instructions.
When my computer restarts and I select from the "install macOS" option in clover,
it starts very well, with a big apple in the center of the screen and the white little bar
under it, showing the process status.
My problem is that, when it has gone through about 50% the process appears to stop, and,
then, this white "spinner" appears under the white bar and start to circle around (just
like waiting for something) until the installation process enters in a "Bear Hug" and
never ends !!!!!!
By the way, let me tell you that the computer NEVER reboots several times as mentioned
in the instructions for installing High Sierra.
So, everytime, I have being forced to cancel the update process and rebooting with my
original Sierra install.
PLEASE, any ideas on how to solve this ?????? Thank in advance !!!
Rafael

Same here. Very slow boot with trim enabled on APFS with non-Apple SSD hardware.
Running without TRIM patch for now. How bad it's for FS?

Any other kexts you are patching apart from IOAHCIBlockStorage?

At this moment with a Samsung SSD 840 EVO 120Gb and clover trim patch working without issues. However, I keep the backup copy in HFS+... I'm not sure if I'll have any problems or not in the future.

Why not to want to convert to the new filesystem? Sorry for the noob question but I just upgraded with APFS and I want to see if it was a bad choise!!

Edit: I saw some of the problems. Thanks anyway

Has any of you tried to run the update avoiding APFS conversion on a CoreStorage SSD + HDD drive? Was it successful?
