Samsung SSD 750 EVO 120GB and 250GB Review

750 EVO SSD – 2D Planar TLC NAND

The Samsung SSD 750 EVO has been shipping since 2015 in Asia, but it was only released in North America in 2016. This SATA III SSD drive represents a new budget line of drives from Samsung that is directly aimed at white box system builders or anyone in the DIY market that is looking for a solid performing low cost storage solution. Samsung rates the sequential read and write speeds up to 540/520 MB/s and 4K QD32 random read and write speeds up to 97,000/88,000 IOPS, thanks to the company’s TurboWrite technology. TurboWrite technology accelerates sequential write speeds by creating a write buffer inside the SSD that simulates more expensive SLC flash memory technology.

Samsung SSD 750 EVO 120Gb & 250GB Storage Drives

Due to the target audience, the Samsung SSD 750 EVO series features just two capacities to pick from; 128GB and 250GB. Suggested retail pricing on the drives is $54.99 for the 120GB ($0.45 per GB) and $74.99 for the 250GB ($0.30 per GB).  We looked around and found that the Samsung SSD 750 EVO 120GB SSD can be purchased this very second on Amazon for $59.90 with free shipping. Not bad considering the Samsung SSD 850 EVO 120GB is $67.99 shipped ($0.57 per GB) and the 850 EVO 250GB is $86.98 shipped ($0.35 per GB). System builders around the world are looking to have the best price points available and a $10 cost savings is a big deal when you are making a large number of systems.

Samsung 750 EVO SSD

How did Samsung keep the costs down even further on this series? Rather than using 3D NAND 3-bit MLC NAND Flash and a triple-core MGX controller like the Samsung SSD 850 EVO series features, the new SSD 750 EVO series uses 2D planar NAND and has one processor core in the controller disabled. To be exact, Samsung is using 128Gb 16nm TLC NAND Flash memory chips and a dual-core version of the MGX controller.

Samsung also moved to a shorter 3-year warranty or the TBW rating. Samsung has placed a 35TBW (Terabytes Written) endurance rating on the 750 EVO 120GB  and 70TBW on the 750 EVO 250GB. The Samsung SSD 850 Series features a 5-year warranty or 75 TBW on the comparable 120GB and 250GB drives. So, for roughly $10 you are getting different NAND, the Samsung MGX controller with some things disabled and a shorter warranty period & endurance rating.  The Samsung SSD 850 EVO 250GB drive also has 512MB of DDR3 cache, which is double the amount on the 750 EVO 250GB. Enthusiasts and prosumers likely just turned their nose up, but that again, they aren’t the market for this drive.

    Legit Bottom Line:
    The Samsung SSD 750 EVO series offers solid performance, but the Samsung
    SSD 850 EVO series is just dollars more and offers better everything!
    Would have been nice if there was a 250 GB-850 EVO in the charts for comparison

    • Nathan Kirsch

      If I had one here to bench mark I would have included it! The smallest drive I have is the 850 EVO 500GB!
