Upgrading the hard drive from HDD to SDD or SSHD
I have acquired a iMac 9,1 last year and i'm happy with it and thinking of upgrading the actual 640G with SSD with the following ideas but can't seem to find the right drives SATA II compatibles. I can do Adobe Photoshop and Illustrator good. I'm maxed at 8G on memory :
Idea 01 :
- Change 640g HDD to 256g SDD or 500g SSD
- Keep HDD external as a Time Machine
Idea 02 :
- Change 640g HDD to 1T SSHD
- Keep HDD external as a Time Machine
Idea 03 :
- Keep 640g HDD internal for (Data)
- Add 128 SSD (for OS and Apps) by replacing Optical Drive
I don't want to spend more than 250$ and my question which seems the most efficient way to have the iMac last longer - hoping a few more years. Also looking for some compatible drives that would do the job. Saw some complet solution (Drive - tools) at macsales.com but i'm still looking and was wondering if there were others options into shopping to these drives.
Is this a good question?
