Review Samsung 850 EVO 120 GB SSD

 Adding an SSD is something you must look at if you are obsessed with a faster PC or Laptop. I usually like the PC or Laptop to be responsive and SSD is the best way to make that happen. Even if you are running your PC on top of the Line core i7 and 16 GB RAM, you will still gain a lot of speed if you add up an SSD.

The SSD we added to our PC is one of the best available in the market without breaking the bank. The Samsung 850 EVO 120 GB costs close to Rs. 5,000 or $85.

The SSD is fast and offers great performance to the users looking forward to upgrading from a 5400 RPM or even a 7200 RPM Hard Drive.

The SSD Design and Form Factor: It is quite tiny with 2.5-inch frame and very light in weight. You can have a look at the form factor and design below.

Installation & Setup of Windows on Samsung 850 EVO 120 GB SSD

We had our windows 8.1 running on the Hard drive before we integrated the SSD into the system. There are a lot of software which helps you clone the Hard Disk content to the SSD and then you can boot from the SSD. Physical installation is pretty easy comes with an SSD bay which you can easily fit in your PC cabinet and fasten it with two small screws. First, you will need to fit the SSD to the bay which comes along with the SSD or your cabinet.

We took a more traditional approach and in my experience is a more trouble-free solution as well. We removed the OS from the hard drive partition and reinstalled it on the SSD.

Doing a clean install is fairly easy for Windows 8.1 here are simple steps you can follow:

  1. Create a windows 8.1 bootable pen drive or flash drive using the Rufus software. (you can read how to do that on internet there are several simple guides).
  2. Back up all the data on the C Drive partition to other partition or drive. In our case, our hard drive had two partition C and D. On C partition we had windows installed.
  3. Open PC cabinet, remove the HDD and plug in the SSD with the SATA cable.
  4. Plugin Windows Flash Drive and do a clean install of Windows.
  5. Boot from SSD and see if everything is working fine.
  6. Plug back the Hard Drive to another SATA cable, you can format the C partition which also has Windows, PC may not boot if both SSD and C partition has windows.
  7. Copy back your data to the Hard Drive, install the necessary drivers on the SSD and Samsung magic software that comes bundled with the SSD.

Performance Samsung 850 EVO 128 GB SSD:

You will definitely feel the performance difference once you make a shift from the traditional HDD to an SSD. The bootup time for the PC got reduced drastically below 20 seconds from over 45 seconds and the general working on the internet, opening closing tabs and word documents etc sped up. Loading time for PC games also improved though no increase in frame rates after installing the SSD.


Our Samsung SSD is plugged into a SATA 3GB/Sec cable and plugging it to the SATA 6.0 GB/Sec cable may give some more boost.

SSD profile is set to reliability, putting the SSD in Rapid mode may also enhance the performance.

System – Z97 motherboard, Intel Core i5 3570K clocked at 3.4 GHz, with 8 GB of Corsair RAM.

Looking at the performance we are quite happy to run the drive. Considering the performance of the peers we found Samsung 850 EVO is at par or faster than the Transcend, ADATA SSD’s which we have tested earlier. For a price tag which is slightly higher compared to the competition, Samsung SSD proves it worth by offering great performance and reliability. We have been using this SSD now for more than 6 months and have never faced any issues to date.

If you are looking to upgrade to an SSD, Samsung SSD can be a good choice.
