I am going to update my late 2012 iMac from 8 to 16 gigs of RAM and an internal SSD to replace the original HD.I am hoping someone can recommend the best options or just point me in the direction of an online retailer that can properly consult me.
You are already using an external? I did not know that. There is a advantage if your willing to take the co mouser apart. I’m getting 450ish read/write and that’s pretty good for 120.00 and no labor.
I followed advice from another member on this. The best wat is internal, if you want to take it all apart.
Another option you can do with these older iMacs is replace the optical drive with an SSD as well. In that case you can run two SSDs in RAID0, or one SSD for your OS, one SSD for your user accounts etc.
My older 2009 iMac is still running strong. The optical drive bay SSD is an older 128GB SSD that has the OS install. The HD Bay has a 1TB SSD that has all the system user accounts.
