how can I format a KC1000 ssd to 4K ?
And is there any guide for installing these SSDs to macbook pro?
1. I used
Unetbootin to make an Ubuntu 17.10 live CD (on a USB disk). Once you download the app, you can select Ubuntu, and then the 17.10 Live CD option. It will automatically download the ISO and copy it to a USB drive for you.
2. Turn off your macbook. Plug-in your ubuntu live USB. Turn it on and press the 'alt/option' key to get to the boot options menu. You can select booting from the ubuntu drive. Once ubuntu loads, you can format the ssd as follows (
summarized from reply #163):
2a. In the Unity Dash (hit the cmd key to get there), search for 'Software and Updates'. In that window, check the box that says 'Community-maintained free and open-source software (universe).
2b. Open the terminal (search for terminal in the Unity Dash), and type the following:
>>
sudo apt-get install nvme-cli
>>sudo nvme format -l 1 /dev/nvme0
This should properly format your nvme drive as 4k block sizes. You can click on reply#163 link to see how to verify that.
3. Turn off the computer (menu on the top right). Remove the Ubuntu USB drive, and connect the macOS recovery drive/ timemachine backup to format the drive and re-install macOS.
Hope that helps.

I also wanted to add that this forum post has been really helpful for me in figuring out the drive I should use, and the steps to get the drive installed/ OS installed, etc. Just to add the the other data points, I used a 480 GB KC1000 ssd to upgrade as well. For other folks attempting to upgrade, this was my workflow:
1. Installed the drive using the sintech adapter. I didn't put any tape or support below the drive. I don't think the sintech adapter needs tape for insulation. As for support, probably a good idea, as there is 3mm or so gap between the drive and the base of the laptop. I just didn't have anything to put there.
2. After installation, formatted the new drive to 4k logical sectors using some an Ubuntu Live USB disk.
3. Used a recovery drive (that I made by downloading macOS 10.13 from the Mac App Store and following apple's guide) to do a clean install. A couple of notes here: First, I went into Disk Utility, and in one of the menus (maybe View), selected 'show all devices', closed the Disk Utility, and then re-loaded it. Only after that I saw the new drive. I formatted it as HFS+ journaled (not APFS, as that gave me trouble during installation. Also, during installation, macOS 10.13 will automatically make the APFS container). I started the installation and let it finish. When it was done installing, it asked me to migrate my old profile via the Migration Assistant. I said yes, connected my timeline backup, and started letting it copy my old data. Several notes in the next points.
3b. The things I did in step 3 were after several failed tries recovering my old profile. Just recovering the old profile directly (without going through a clean install) always (5 times) resulted in a failed recovery. Maybe it's because the old drive was 128 GB and the new one was 480 GB. I had two separate backup sources, and both failed repeatedly. So definitely do a clean install first, and then copy the old profile over.
3c. When you start migrating your old profile via time machine, it may ask you to update a program (iTunes in my case). DON'T upgrade. You can upgrade once you boot into the new drive. If you update, it makes a new profile, and messes up your restoration (you are forced to make a new account, and it's just more trouble than its worth). SKIP the upgrade, and let it copy the profile data.
4. Once the data is copied, it will ask let you log-in to your new drive/OS/computer. Everything should be ready to go. Now you can log-in to your Apple account and apply any upgrades to the OS, and you'll be good to go.
