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!

SSD SPECIFICATIONS

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.

SSD COMPONENTS

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.

Which one is the 256MB DRAM chip? I saw a controller, two NAND package(one on each side), and one small chip which Iooks like power management chip.

dram is integrated into controller on 750 EVO.
“The 750 EVO also crams a 256MB DDR3 memory module in the same package as the MGX controller, which should reduce latency between the processor and its DRAM buffer. This is the first time we’ve seen the advanced design in a Samsung SSD.”

Wow, thats pretty mad. Although not unheard of. Mobile SoCs were using something like this for years.

They should release 650 for consumers. Would perform a little bit worse (due to lack of dram) but would probobly be priced lower aswell. Perfect for those seeking the cheapest thing possible.

Honestly, we would love to see this drive released to consumers. It’s priced very well and you get decent SATA III performance out of it. Never mind the fact that you can through it in RAPID mode through Samsung Magician as well.

rapid is just a pointless gimmick, nothing else.

It’s still an added feature, consider it what you like. Regardless, the point being that the 750 really should be a consumer driver

You want Cheaper? Buy chalk and a board?

Sarcasm aside (my bad); try run a profitable business for a year.

Samsung is a _big_ company, so i’m sure it can afford to sell cheap entry level SSDs for minimal margin.

Beside, Sammy is vertically integrated, so per unit they probably have the lowest cost (having your own fabs, controller and firmware knowhow does have its benefits).

Hello,
What was your average temperature during tests ?

I use mine in a Lenovo G580,and my average temperature is 45degrees,sometimes it goes up to 50.
Is it normal?

Thank you!

IDK, but 850 offers thermal guard which alters the system’s temperature when it reaches a certain degree

Which is best of 850 and 750?? Both with 250gb.

DIFFERENCE BTWEEN THEM is that 850 has 1 gb of Ddr3 while 750 has 256mb of DDR3. 850 also offers dynamic thermal guard, which alters the system temperature when it reaches a certain degree, and it has 3d VNAD (only useful for high capacity ssds, as 2D Nand can only reach up to 250gb. 750 offers 2d NAND. Speed difference is minimal

Nice article … of course BUT
Your tests are not valid, you did speed test on 256MB ! and 1GB file size.
First one is exactly size of dram inside SSD.
Valid test should be on 16GB or more.
