iMac Intel 21.5" Retina 4K Display (2017) Blade SSD Replacement

소개

Use this guide to replace the Apple custom blade SSD (NVMe/PCIe x4).

This guide is intended for iMac Intel 21.5" EMC 2545 models that are equipped with an SSD (Fusion Drive or blade SSD configurations).

If your system does not already have a blade SSD installed you won’t be able to install it later as the connector and the support components are not present on the logic board.

iMac Intel 21.5" Cardboard Service Wedge

$4.99

구매

With the hinge free to move, the iMac will be unbalanced and hard to work on. Repairs can be completed as shown, but are faster and easier with an iMac service wedge.
If you are using the iFixit cardboard service wedge, follow these assembly directions to put it together.
Before beginning any work on your iMac: Unplug the computer and press and hold the power button for ten seconds to discharge the power supply's capacitors.
Be very careful not to touch the capacitor leads or any exposed solder joints on the back of the power supply. Only handle the board by the edges.

Starting on the left of the display, near the power button, insert the iMac Opening Tool into the gap between the glass panel and the rear enclosure.
The hub on the iMac Opening Tool will keep you from pushing the wheel in too far. If using a different tool, insert no more than 3/8" into the display. Otherwise, you risk severing antenna cables and causing serious damage.
Be gentle! The glass may crack if pried too much. Use a hairdryer to heat the edges and loosen the tape if the room temperatures are low.

Use the tool like a pizza cutter—roll it along through the gap, and it will cut the foam adhesive through the center.
Be sure to always push with the handle behind the cutting wheel. If you pull, the wheel might get pulled out of the handle.
Run the tool up along the left side of the display.

Plastic Cards

$2.99

구매

While the opening tool cut most of the adhesive, the display will still be slightly adhered to the case. A plastic card will be necessary to free up the last of this adhesive.
Set the iMac face-up on a table.
Starting from the top right corner of the iMac, wedge a plastic card between the display and frame.
Be careful not to insert the plastic card more than 3/8", or you may damage internal components.

번역하기

11 단계

Gently twist the plastic card sideways to create a gap between the display and frame.
Move slowly and be careful not to stress the display glass too much—you only need to make a gap of about 1/4".

With both plastic cards inserted as shown near the corners, gently twist the cards sideways to increase the gap between display and case.
If there are any sections that seem to stick and won't separate, stop twisting and use one of the cards to cut the remaining adhesive.
Begin to lift the top of the display up from the frame.
Only lift the display a few inches—the display data and power cables are still connected to the logic board.

While holding the display up with one hand, use the other hand to unplug the display power cable. Make sure that you pull the cable out from the plastic tab, and not by pulling on the color wires.
Lift the display up enough to have easy access to the connector, but not so much that you stretch the cables and stress their connections (about 8").

Many thanks for the tutorial? Very detailed and helpful. Now, my question is, can I replace the existing SSD PCIe blade by ANY PCIe blade?

I mean, the 2017 4K iMacs have a PCIe v3 with 4 channels. Will it admit an older PCIe version (such as v2)?

Aleix - 2018년 6월 12일 답글

Apple uses a different interface than the M.2 blades as such you ned to use theirs or either of the two 3rd party drive makers OWC or Transcend

- BeetsTech - The Ultimate Guide to Apple’s Proprietary SSD’s (Apples SSD’s)

- OWC - Aura Pro SSD

- Transcend - JetDrive 820

Dan - 2018년 6월 12일

Hello Dan! Many thanks for your answer, but none of the webpages you mention has a blade PCIe SSD compatible with the iMac 4K 2017… :(

Aleix - 2018년 6월 13일 답글

I’ve put in few of the BeetsTech blades in with no issues. Are you trying to install the SATA drive?

Dan - 2018년 6월 13일

Hi Dan! The initial intention was to replace the current 28GB blade PCIe SSD by a bigger one, 225 or 500GB, and keep the current sATA 1TB drive. This way, I could have a decent and fast FusionDrive, as the current configuration is pretty slow…

Finally, I’ve decided to replace the current 1TB sATA 5400rpm drive by a 1TB sATA SSD, as the total cost is arround the same as replacing the blade PCIe drive. In adittion, I am not 100% sure which blade PCIe drive will work on my iMac… the support guys from OWC say that they don’t have a compatible drive yet :(
