Now, if I interpret the information at Mactracker correctly, the SSD part in the 2013 iMac uses a 5 GT/s PCIe x2 connection (meaning PCIe 2.0, two lanes) which translates into 1 GB/s as possible transfer speed. With a Fusion drive, things are fast most of the time but then for some things the disk access slows down considerably. In regard to speed, you should notice foremost more consistency. While some work (that you and me would outsource), certainly doable and mostlylost has already linked to a supplier of the needed parts.
You need an adaptor to go from 3.5' SATA to 2.5' SATA including something that keeps the SSD in place and you have to remove the screen off the iMac. At the moment, around 1Tb is used.Īs already said, the 3 TB HDD part of your 3 TB Fusion drive can 'relatively easily' be replaced with an SSD as it uses a SATA connection. Is it possible to replace the Fusion Drive with a 2Tb SSD? If so, will I notice a lot of (speed) difference? I'm working with large (photo)files in Lightroom and other software. I'm working on a late 2013 iMac 27' i7, 3Tb Fusion Drive/ 32Gb Memory.ġ. I just have a few questions about Fusion Drive vs.
