Thanks for previous input on SSD vs Hard drive vs. Fusion in iMac. I am now deciding between SSD and Fusion. I read in one of the Forums that there could be a reliability issue with Fusion due to Hard Drive Failure and that jogged my memory that several yrs ago I had to replace my hard drive. What is the probability of hard drive failure with newer computers--mine now is 8 yrs old. With SSD this not an issue. My one issue with the 256 GB drive, which I may get is running out of memory and needing external storage which I would rather not deal with. I have used only 180-190 out of 500 GB in my 8 year old Mac, so this would probably not be an issue, but who knows what the future holds. Any ideas about this. Thanks in advance for your input.
