Hi everybody, I have a question about my iMac 27’ late 2012 with Fusion drive 1TB, I would make an upgrade and swap my HDD with an internal SSD, what ssd would you recommend ? I must know any particular thing to swap the HDD ? I know that for swapping I must buy a thermal sensor to control the fans or install the control fan app and Thanks a lot guys Luca
First I would break the Fusion Drive set so you can replace either the SATA HD or custom PCIe 2.0 blade SSD. Here’s whats needed: How to split up a Fusion Drive As to which way to go I would recommend replacing the blade SSD as being the better direction! While a bit more work it will give you a lot more performance! Here’s what you want: OWC 1 TB Aura SSD. Here’s the other possible options: Aura SSD’s if you don’t need such a large SSD given you aren’t replacing the HD. And here is the IFIXIT guide to follow: iMac Intel 27" EMC 2546 SSD Replacement. This allows you to hang onto the deeper HD storage for your data! If you still want to go with the HD swap out to SSD here is the IFIXIT guide: iMac Intel 27" EMC 2546 Hard Drive Replacement and you’ll need an adapter frame to support the 2.5" SATA SSD into the 3.5" HDD frame: OWC 2.5" to 3.5" Drive Adapter Bracket and the in-line sensor: OWC In-line Digital Thermal Sensor for Hard Drive Upgrade for 27" iMacs 2012 and Later Don’t forget you still have a 32 GB blade SSD in your system which is almost useless in a dual drive config. Which is why I prefer to replace it and also gain the higher I/O of the PCIe bus. Apple slims 1 TB Fusion Drive down to a measly 24 GB of flash storage
