HD drive upgrade to SSD


I have a Fusion Drive in my 27" 5k iMac (2015). It has a 1 TB HD drive and 32 GB PCI SSD which together make up the Fusion Drive

I am considering replacing the HD drive for a SSD. From the posts here I know I need the inline thermal sensor cable from OWC.

Is this upgrade of HD to SSD worth it in terms of performance?

Also do I need to change anything when I do the format of the new SSD. I assume the OS-X will boot from the PCIe SSD In the motherboard ?

thx for excellent website

From what you've listed here you have a kick ass system.

What is the issue you think you need more performance as one could go a few different ways here some easier than others, and cheaper!

Can you describe what you are doing. Are you working with large files (music and/or vids), Gaming, or Coding ?

OK, what do??

I would not swap out the internal HD for a SSD it won't improve things enough. I would look at adding some RAM if you think you are going to work on large projects and/or have a lot of windows open at once.

Next I would look at the way the system is configured. Do you have a lot of open windows when you shutdown which are re-opened when you turn your system on? Do you pre-load apps? While these can be helpful they do tax the system as unlike a dual drive setup the OS is trying to balance what is held in the SSD Vs the HD under the Fusion Drive.

Frankly, if you really want all the apps loaded and/or reload after restarting I would split the Fusion Drive back down to a dual drive setup and then manage where things sit manually. As the OS and Apps would be on the SSD it would be technically faster in loading. Leaving the other stuff on the slower HD only to be accessed when I want it.

No mostly photos, music and office documents

I have a 2011 imac 27 inch which i upgraded the hdd with an ssd and it actually seems faster than the newer one

Theoretically the non operating files and most commonly used files run off the 32G ssd PCiE on motherboard

This is not very big so surely replacing the Hdd 1T with a SSD will be a big improvement or is it better to upgrade the 16G RAM ?( although i dont do any gaming or videos)


When you compare things you need to make sure you don't bias things. As an example here the CPU you have in the older system maybe a i7 quad now you have a i5 quad here. Which gets into how many threads can be running at the same time 8 (i7) or 4 (i5). The i7 would beat the i5 with the same drive.

Then we need to look at the SSD's I/O your older system has a SATA 6.0 Gb/s interface unlike your newer system which has a PCIe x4 lane which is much faster than the SATA interface!

Confused?? ;-} Not trying to here just is. Here's a good read: Everything you need to know about NVMe, the insanely fast future for SSDs
