Samsung 750 EVO SSD Review (120GB/250GB)

Once every so often we get to look at a solid state drive that stands out from the crowd. A recent out stander to the storage scene was the Intel 750 NVMe PCIe SSD that we have grown to love. What if, you’re just entering the storage industry, or even less yet, just purchasing your first prebuilt PC or bare bones kit, and want it to include an SSD? Samsung has the answer, the Samsung 750 EVO SSD!

This client driven SSD has two goals in mind, be fast and inexpensive. Based upon, the specifications we have been given, the Samsung 750 EVO easily accomplishes this feat. This also really shows how Samsung is overtaking pretty much every single storage market that presently active. Enough about market trends, let’s see how this drive performs!


The Samsung 750 EVO SSD will be available in 120 and 250GB capacities, and as we previously mentioned, will be specifically marketed towards client PC’s. The pricing is extremely reasonable at $54.99 for the 120GB and $74.99 for the 250GB. This puts the drive at a mere $0.29/GB, not too shabby.

While our samples were not shipped with the packaging, you can expect to see the Samsung 750 EVO with a look similar to the image below.

How about speeds? The Samsung 750 EVO can reach a sequential read speed of up to 540 MB/s and a sequential write speed of up to 520 MB/s, this is for both capacities. When it comes to random 4KB performance at 1 queue depth, we can expect to see 10,000 IOPS for read and 35,000 IOPS for write. The Samsung 850 is listed to reach just over this at 40,000 write IOPS.

On top of this, the drive also feature AE 256-bit data security for Full Desk Encryption and is also a TCG/Opal v2.0 encrypted drive (IEEE1667). Samsung lists this drive to have a three year limited warranty, two year shy of the Samsung 850, and lists the MTBF to 1.5 million hours for reliability.

The endurance of this drive is listed bit lower than the Samsung 850 SSD, as the 120GB features up to 35 TBW (75TBW for the 850) and 70TBW for the 250GB (150TBW for the 850).

The power consumption for the Samsung 750 EVO is listed at 50 mW for idle, and 6mW for Dev. sleep, which is 4mW higher than the Samsung 850.


The front of the Samsung 750 EVO features the stereotypical Samsung design, a plain black aluminum housing with Samsung Solid State Drive listed smack in the middle. This 2.5″ form factor features a SATA 6Gb/s interface that is backwards compatible to SATA 3Gb/s and SATA 1.5Gb/s.

On the flip side, we see a bit more about the SSD, this includes the part, serial and model number, as well as the listed capacities. Underneath the product label you will find two screws, in addition to the one exposed, which allows us to sneak a peek under the hood of this SSD.

As you can see, these SSD’s both use the quarter length PCB, and feature Samsung controller, NAND and DRAM.

The controller of these SSD’s is Samsung’s MDX controller, which is designed for low capacity and typical client PC usage patterns. Both drives features Samsung’s DRAM cache memory of 256MB DDR3.

On the 120GB capacity, there is a single planar Samsung NAND flash module (K90Kgy8S7D), which boasts the whole 128GB capacity. This capacity is left with a usable space of about 112GB, which means the remainder is used for firmware and over provisioning.

The 250GB capacity features two planar Samsung NAND flash modules, with the same model number, where each would hold 128GB in capacity. The 250GB capacity is left with 233GB of usable space, with of course the over provisioning and firmware accounted for.
