DIY - Lets take this 2013 iMac apart and upgrade to SSD!

[bent christian]

Installed Samsung Evo 850 Pro 1TB SSD in my late 2013 iMac today. Used a 3.5" to 2.5" adapter from OWC, as well as their thermal sensor.

Wow. Those are low benchmarks. Totally not worth it, IMO. Speeds are only marginally better than booting via USB 3.0 (400/430).
