Samsung SSD 850 EVO Upgrade

0

Needing a spare solid state drive (SSD) for a side project, I purchased the highly rated Samsung 850 EVO SSD to replace my aging OCZ Agility III SSD on my workstation.

Since this entailed upgrading my main boot disk, I booted into my system, used a SATA-to-USB 3 cable to connect the new SSD as an external drive, formatted it as an OS X Extended Journaled partition (GUID partition map scheme), cloned my original OS X SSD to the new SSD using Carbon Copy Cloner, installed Clover EFI bootloader to the new SSD, and copied my old Clover EFI partition files to the new one. Yes, that’s a lot of steps in one sentence, so drop me a comment if you need clarification.

I used Blackmagic’s Disk Speed Test (free off the Mac App Store) to benchmark the old and new SSD. The results speak for themselves:

OCZ Agility 3 (old SSD)
OCZ Agility 3 (old SSD)
Samsung 850 EVO (new SSD)

I’ve definitely noticed more responsiveness throughout the system and look forward to taking advantage of the increased SSD capacity too. 🙂
