Per your request from the below quoted text,
elaborating on this step: Use more than one EFI partition. A drive can
have more than one EFI partition. Additional EFI partitions do not
have to reside at the beginning of the drive.
here is some info (I will make edits shortly when I have more time):
An EFI partition (sometimes referred to as an ESP ...
I think I may be able to help you triple boot, although I haven't tried triple booting yet. I do know how to install Windows on a separate SSD, and I'm pretty sure you can just install Linux by partitioning the SSD. Here are the steps:
Step 1: First, you have to install both Windows 10 and Ubuntu ISO files. Ubuntu from here: Ubuntu ISO File, and Windows 10 ...
Yes, it is likely to be compatible - however there are (ofcourse) no guarantees.
According to the manufacturer of the adapter, they have tested that specific SSD with the adapter - so that sounds reasonable.
I would consider using this specific adapter from the same company:
It is listed as supporting ...
These models support a 7 mm tall SATA III (6 Gb/s) hard drive for the primary storage (using the 3.5" size as opposed to the 2.5"), and getting the Fusion drive means you'll also get what's called a small "blade" SSD via a PCIe connector. Without this you can't attempt what you're wanting to do.
So, in summary:
Primary storage uses a 3.5" 6 Gb/s SATA 3.0 ...
Disk Utility looks like it's pre-Yosemite [skeuomorphic dots top left] which will have no idea what APFS is.
Try booting to Internet Recovery using Cmd ⌘ Opt ⌥ R & you should get the chance to install the latest OS the machine can run, rather than the one it came with.
You should also get a Disk Utility that understands APFS.
Hi I think you'll notice a HUGE difference if you put in an SDD and max out the memory. I did both to my machine and it was wonderful. I've also got a 2009 i-mac, 27 inch, but with 2.8 Ghz Intel Core i7. I upgraded mine with 32GB memory (a few websites said it was possible at it has worked well on my machine) and also replaced the optical drive with an SSD (...
I see a drops of 17% (write) and 25% (read) when using encrypted vs non encrypted (One APFS container with APFS Volumes).
It seems that the 40% drop you experience is high in comparison, but it is hard to tell with so little data.
APFS Volume type | Write (MB/s) | Read (MB/s)
apfs | 912 | 919
apfs encrypted | 756 | 688
Using case-sensitive or not made ...
There is a very similar problem here, and a solution. SSD in a MacBook Pro (mid 2012, 13"), Finder symbol with question mark. You need a new internal SATA disk connector cable to work with the new SSD. I have encountered the same problem with my MBP mid-2012 and a new Samsung 860 EVO SSA.
