Can I Upgrade the SSD and add an SATA SDD?

Hello

In this iMac Intel 21.5" Retina 4K Display (2015) it has an APPLE SSD SM0256G fitted, I *think* this is a PCI Express card - google is bit vague. Assuming that it is I would like to fit a large SSD - a Samsung 850 Pro 1TB - into the SATA hard drive bay inside the Mac. Is this possible?

Also, I would like to replace the existing SM0256G with a larger drive, such as the Samsung 960 PRO M.2-2280 512GB PCI Express 3.0 x4 NVMe Solid State Drive, Or is it a proprietary connector?

Thanks

Karl

Let's see if we can clear some things up. Apple uses a custom blade SSD in their systems so you really can't use just any SSD that looks similar.

You didn't tell us if you have a HD installed already, so you may need to review your hardware using the 'About This Mac' > System Report to see what you have. If you don't then you'll need to get a cable harness and the rubber boot that supports the drive. At which point you could install a 2.5" SATA SSD.

As for upgrading the current blade drive I would leave your current SSD alone. It's a PCIe 2.0 AHCI 250 GB drive which is ideal as the boot drive & host your apps.

Karl heres the IFIXIT guide you'll need to follow: iMac Intel 21.5インチ Retina 4K Displayロジックボードの交換 as you'll need to get to the back side of the logic board to plug in the SATA cable. Jump down to Step63. Its a bit too tight to do blindly. Make sure you use the correct tools to take the display off as you can damage it quite easily.

Here's the parts you'll need:

Hello Dan

Thanks. I don't have a HD installed, so I will be needing the cable harness and the rubber boot as you mention. I can't see them in the iFixit shop, do you know of a supplier? I can only find parts for the 27" 2015 model.

Thanks

Karl.

Hello Dan

Awesome, parts ordered. That Bookyard firm never appeared in any of my searches. I already have the iFixit tools for screen removal and I'm expecting the work I have to do to get this done to be difficult.

Thanks Again

Karl.
