Samsung 850 EVO and 850 PRO 2TB SSDs Review

Samsung 850 EVO and Pro 2TB SSD




Both drives are packaged as we've come to expect from their respective lineage. The 850 EVO in a white themed box and the 850 PRO in a black themed box.




On the rear of the packaging, Samsung advertises the 850 EVO's 5-year limited warranty and the 850 PRO's 10-year limited warranty.




Inside the box, both drives are protected from damage by a black plastic tray.




The front half of both drives have a "Samsung" label and a colored square that denotes the series they belong to. Grey for the EVO and dark Red for the PRO.




The back half of the drives have a manufacturer's label that lists all the specifics for each model.




We ran into a problem trying to open the 850 PRO. We couldn't do it because the pentalobe screws stripped. We had no problem opening the EVO with the appropriate pentalobe driver. Sadly, we are only able to show you the internals of the EVO. We will assume they are very similar to one-another.




Located on this side of the EVO's internal PCB are located the drive's MHX controller, a single 2GB LPDDR package and four of the drives eight 256GB 3D flash packages.




On the opposite side of the PCB are located the remaining four 256GB 3D flash packages.
