So you had better make a backup, before you do this. a DIY one) the answer is YES - I have just broken up my Fusion drive back to two drives - but note you will destroy the file system on both the old SSD and the HDD.

If the fusion drive was an Apple one, DO NOT ATTEMPT THIS as you will end up with a drive hardware that can't be formatted nor a system installed. Is it possible to replace only the SSD part of a Fusion Drive (so from around 120Gb SSD now.to let's say 2Tb SSD ). I'm working with large (photo)files in Lightroom and other software. If so, will I notice a lot of (speed) difference? Thank you Noirdesir for your extensive reaction! Format it and restore the old Fusion volume's contents from your backup.Create a new Fusion volume using Terminal commands.Do surgery on the iMac to replace the SSD stick.Dissolve the Fusion volume using Terminal commands.Back up everything on the Fusion volume (and on other partitions of the internal hard drive) – including making a bootable backup disk.If larger sticks were available, you'd still need to Getting the part would only be part of the battle. So unless some other vendor has a lead on parts that these two do not – or you could get an Authorized Apple Repair Facility to sell you one of the larger SSD sticks originally used to build Late 2013 SSD-only iMacs – the answer is probably "No." Both advertise 2.5" SATA SSDs for use with the Late 2013 iMac, but neither advertise SSD sticks for use with it.

Other World Computing (MacSales) and Crucial (Micron) are two of the usual "go to" vendors for Mac upgrades. That depends on the availability of larger SSD sticks. This would not be easy, as the HDD bay is not designed to be user-serviceable – but it would be possible. Is it possible to replace the Fusion Drive with a 2Tb SSD? Is it possible to replace only the SSD part of a Fusion Drive (so from around 120Gb SSD now.to let's say 2Tb SSD ).still keeping the HDD part and in effect creating a new Fusion Drive system (but with much larger SSD)?Īs already linked to, it's possible, but I don't know of any vendor selling the required part as Apple tends to use custom connectors for its PCIe SSDs.ġ. I don't know of anybody ever having tried this but it might be a very interesting configuration (and a cheaper way to get 2 TB of overall very fast storage than a 2 TB PCIe SSD from Apple.Ģ. If the iMac had been a more recent one, which offer increasingly faster SSD speeds with the latest one going beyond 2 TB/s, it might have made sense to create a new Fusion drive based the very fast 128 GB SSD part and your new 2 TB SATA SSD. There are other performance aspects than transfer speed like random access time and I don't really know whether a four-year old PCIe SSD does better in those than a 2017 SATA SSD. Which brings us back to speed being more consistently fast (even if a bit slower for some things). The point of this comparison of numbers is that going from a Fusion drive that offers speeds of maybe 700 to 800 MB/s to a pure SATA SSD offering about 550 MB/s can in principle mean a small stepdown in speed for some tasks. Whether the built-in SSD matches that rate is unknown but presumably it should deliver more than what is possible with a SATA connection (about 550 MB/s). 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.
