Hi, I believe my HDD has some fault as sometimes my iMac (5k late 2014) get’s really slow.
So I would have basically 2 options:
* install an SSD instead of a HDD and not use the fusion drive, but the blade SSD as a separate volume
* replace the 3TB HDD like for like
The first solution doesn’t give much benefit, as the fusion drive is quite fast already, but it is quite expensive with a 4 TB SDD (I use 2,5 TB now so 4GB the size to go for)
The second solution (replacing the HDD) costs 80 Eur for the disk and something for the adhesives and that’s it. I also believe that economically that makes more sense as the machine is quite old already
