Yes i upgrade it , got one issue i cannot remote using realvnc ..I'm not sure what file system unless i can remote access it .Installation take 1 hour + time. Dam pretty sad for 2018 in external 3.1 gen 2 ssd and imac 2017Has anyone upgraded their external SSD from High Sierra to Mac OS Mojave yet?
Does it work or do i have to do a clean install?
Is there a way to prevent conversion of the file format to APFS when upgrading?
Yep same....very slow bootupsIt works but it converted it to APFS and I'm now getting slow bootups.

There are pros and cons of doing it either way.
You have to "weigh them" and decide.
It's really up to you.
I reckon using an external USB3 SSD (such as a Samsung t5 or Sandisk Extreme) will give you about 80-85% or so of the speeds you would see if the drive was internally-installed.
Is that 15% or so worth the extra $$$ to you?
Also, when it's time to move on to another Mac, it's simple to disconnect the USB3 drive, and just "take it with you" -- no prying apart the iMac a second time to "get at it".
Tom also asked:
"one more question, are you using USB 3 or USB C?"
USB-c -IS- USB3 (well, actually, it's USB3.1 gen2).
Again, either a Samsung t5 or Sandisk Extreme will "plug right in", just like that.
Then -- erase them (MAKE SURE you get any factory-installed software GONE).
Then -- either install a copy of the OS, or "clone one over" from your internal drive (either CarbonCopyCloner or SuperDuper will do this, both are free to download and use for 30 days).
I suggest CCC because it should also clone over the recovery partition.

MacOS SSD 500GB is the name I gave the T5. I choose it when holding option on start up, but want to make it the default startup drive when I restart or turn on computer.
Here is the screen shots
Today, I downloaded the Samsung Portable SSD app from their website, and I updated the firmware on the T5 drive. I'm hoping that will help. I'll report back if it does.
[doublepost=1545080182][/doublepost]Hi,"Hi, has anyone used the Samsung x5?"
I'll guess that whether or not this would yield additional speed, depends on which Mac you're connecting it to.
Perhaps with a 2017 iMac (which has thunderbolt3) it would work well.
But with 2015 and earlier iMacs, I'm thinking that the speeds obtained wouldn't justify the greater expense of the x5.
My estimation: probably not worth it.
The t5 offers the best "bang for the buck".

"X5 500gb version costs 250$ at amazon. Does it worth for iMac 27 2017 with 2tb fusion drive?"
2017 iMac has Tbolt3, so it should work fine.
If you get one, please come back to the thread and give us a report on how it works, drive speeds, etc...
