Unlike many here who have their own shop, I was a contract worker jumping around larger corporate customers configuring & fixing their equipment.
Apple’s move to system’s without USB-A ports forced a few of my customers to walk away from Apple gear as they were dependent on cypher keys which need to be directly attached to the system, not via a dongle or hub device which could be altered unbeknownst to the user (man in the middle attack risk). For my other big customers the lack of the ability to memorialize a systems drive or remove it so it could be destroyed was the other downfall for Apple.
So I’ve been working out of my home fixing systems as I could over the last few years.
Well, its finally happened! I’ve, fixed my last system for now. My arthritis has finally made it too hard to do much of anything delicate in the cold weather. Maybe in the late spring I’ll give it ago again.
I’m still helping people keep their systems running as long as they can be here on iFixit!
I find I can plug the cable in without pulling the logic board fully out, knowing where the socket is and its alignment I can get the cable inserted. Granted, I’ve done it a few times.
Your system came with a PCIe/NVMe blade SSD, thats on the backside of the logic board a pain to get to, its easier to add a second drive in this case a 2.5” SATA SSD like a Samsung 860 EVO. In this case you’ll use your SATA drive for your stuff and use the blade drive to be your boot drive and , apps, leaving the rest of the drive empty! So your OS has room and if your apps need scratch space they can use it as well.
Sorry no, You would need to redesign the SIP module from the ground up!
There’s more to it than the connector, there is a bit of logic also needed.
How so??
A teardown is not a repair manual if that is what you where looking for. How about posting a Question here: Answers
OWC & Transcend offer s few different drives for the different series Apple has produced. Here’s a good reference on the Apple custom SSD’s: The Ultimate Guide to Apple’s Proprietary SSDs. Cody has it updated it with the newest models but they are using the same drives as the last listed.
Your systems specs: 21.5” iMac 4K Retina (Mid-2017)
As noted: This model has a Serial ATA (6 Gb/s) connector for a 2.5" hard drive. If configured with a "Fusion" Drive or an SSD at the initial time of system purchase, it also has a PCIe connector, but this connector is not present if the system only is configured with a hard drive. >> Your system may not have the needed connector! <<
You need a custom Apple SSD or either an OWC or Transcend 3rd party SSD’s
The 21.5” version has discreet cables unlike the 27” version which has the exact same cables but has a heat shrink tube to hold the cables together. this is done to protect the cables from the higher heat and their placement.
The hardware only takes about a half hour, the installing the OS is what takes the time! To speed it up setup an external OS installer drive the faster the drive & interface the faster the install! A thunderbolt RAID’ed SSD is about as fast as you can get it takes just about an hour with it.
