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!
No it’s not required, it all depends on the alignment needed with the new unit.
Sorry It is not M.2, the custom Apple blade SSD connector is not present.
Very dangerous! You’ll stress the cables and the logic board connectors.
There are two versions of the connector depending on the trackpad and logic board. Yours should be like the one I posted.
The other one is more like this one Keyboard Connector
Both the logic board and the trackpad connectors use a compression bar (latch). When you have it in the open state its ZIF but to secure the cable you need to close the latch to hold the cable and make the needed electrical connection Trackpad Flex Connector
The hole is the microphone! The slots on the other side are the speaker grills. Why would you think the AppleWatch has a SIM?? It uses an eSIM like your newer iPhones.
In a Fusion Drive set you have the slower HDD which is the active storage space and then you have the hidden SSD which is the caching drive. Every data block is read or written via the SSD then to the HDD as the SSD is much faster in both access and read & write action. If you look in your drive info you won’t see it as the active volume only the HDD is listed.
Apples imputation of caching is done at the OS level unlike hybrid drives (like Seagate’s SSHD’s). The whole reason caching like either were offered was SSD’s where still very expensive at the time. Even though SSD costs have dropped they are still more costly than the HDD or a SSHD drive or even most Fusion Drive setups. From a performance perspective a dual drive setup where you have a 256/512 GB SSD as your boot drive and use a larger 1TB (or bigger) HDD or SSHH as your data drive for most is the better setup (not using a Fusion Drive)
For serious Music or Video work you’ll want a larger 1 or 2TB SSD and sue the fastest drive I/O the system offers.
Translation: I have an iMac 21.5 Late 2012 (2.7GHz i5) with 8 Gb RAM and 1 TB HDD. The HDD was full at 640 GB and very slow.After researching the Internet, I came across ifixit and read the instructions for RAM expansion to 16 GB and a blade SSD upgrade. After ordering the opening kit, a memory expansion 2 x 8 GB from Crucial (approx. 80, - €) and a Blade OWC Aura 6G 480 GB SSC (120, - €) the iMac was opened, dismantled and the extensions installed according to the instructions. Everything worked perfectly as described! - The HDD was then reduced to 450 GB. Create a copy of the HDD to SSD with Carbon Copy Cloner and then change the start medium. The iMac now runs like new
Not that simple! The PCIe/NVMe blade SSD is much faster than the SATA III (6.0 Gb/s) drive interface. So while the blade SSD is more expensive it might be more useful!
Do keep in mind the Fusion drive you currently have is using both interfaces but the current blade SSD is quite small! Its just being used as a cache drive to your 1TB HDD.
So if your workflow is video or music I would go with the blade SSD a 500GB would be a good size for small projects.
If you want performance the better direction is to install a PCIe blade SSD (OWC) or replace if small Sostituzione SSD Blade iMac Intel 27" Retina 5K Display.
