Will the Samsung EVO 860 SATA III SSD drive work in my system?

"The drive is no different from the older one as far as compatibility, SATA is a set standard Samsung can't really alter things.

The 860 EVO carries over the same functionality as the 850 EVO its a auto sense drive so it will play in SATA I (1.5 Gb/s), SATA II (3.0 Gb/s) & SATA III (6.0 Gb/s) systems which don't require a fixed SATA speed drive.

The real difference is the read/write performance is better with the newer drive.

It would be wise to replace it.

The inside surface of the uppercase are not well finished so the cable tends to wear on the rough surface. Here's the IFIXIT guide you'll need to follow: MacBook Pro 13"" Unibody Late 2011 Hard Drive Cable Replacement and I recommend using the 2012 version of the cable MacBook Pro 13"" Unibody (Mid 2012) Hard Drive Cable as its a better cable.

Even still I would place electricians tape on the uppercase where the cable rests to help protect it. Lastly, don't over bend the bend points as you don't want to fatigued the foil conductors."

Hi, I am having exactly the same problem on a mid 2012 MacBook Pro. Has anyone worked out a solution yet? I really don't want to have wasted my money on an SSD that will not work.

"Hello,

I just tried to install an EVO 860 250GB out of the box on my beginning 2011 MacBook Pro 8,2 A1304 i7 8GB RAM unsuccessfully. The installation process stops at first reboot before language selection with the typical error message that cannot be installed and reboot.

I don't plan changing the HDD cable (which by the way already comes with a plastic tape on it to protect it) by now but will see if any firmware updates or so help in the near future.

I just wanted to contribute with some information that may help others wasting much time on it.

Cheers!"

"Hi!

I've got a mid 2012 13"" Macbook Pro. I've bought a Samsung 860 Evo 600gb.

Initially I just installed the SSD in the HDD bay as you'd expect and attempted a clean install of High Sierra from USB.

The install was excruciatingly slow taking 9 hours. I next attempted to connect the SSD by the USB adapter. The OS installed quickly. I put the SSD back into the internal bay and everything slowed right down; booting took an eternity then clicking anything when it'd booted caused it to lag.

I did think that the SATA cable could have somehow damaged itself in the process but the original drive, back in the Macbook performs normally.

Any solution for this problem?"
