THE SSD REVIEW TEST BENCH AND PROTOCOL
Solid State Drive testing at The SSD Review differs slightly, depending on whether we are looking at consumer or enterprise SSDs. For consumer SSDs, our goal is to test in a system that has been optimized with our SSD Optimization Guide. To see the best performance possible the CPU C states have been disabled, C1E support has been disabled, Enhanced Intel SpeedStep Technology (EIST) has been disabled. Benchmarks for consumer testing are also benchmarks with usually a fresh drive. In our case, this drive has previously been tested at The SSD Review. We benchmark our drives to verify that manufacturer specifications are in line but also, so the consumer can replicate our tests to confirm that they have an SSD that is top-notch. We even provide links to most of the benchmarks used in the report.

BENCHMARK SOFTWARE
The software in use for today’s analysis is typical of many of our reviews and consists of Crystal Disk Info, TRIMcheck, ATTO Disk Benchmark, Crystal Disk Mark, AS SSD, Anvil’s Storage Utilities, Iometer, PCMark Vantage, HD Tune Pro and PCMark 8. We prefer to test with easily accessible software that the consumer can obtain, and in many cases, we even provide links. Our selection of software allows each to build on the last and to provide validation to results already obtained.
Crystal Disk Info is a great tool for displaying the characteristics and health of storage devices. It displays everything from temperatures, to the number of hours the device has been powered, and even to the extent of informing you of the firmware of the device.
120GB
250GB
As we can see, both capacities have been powered on 6 times for quality control purposes and feature SMART attributes, DevSleep and TRIM, but let’s first double check that it is working …
We’ve covered TRIMcheck in the past. It is a great tool that easily lets us see if TRIM is actually functioning on a SSD volume in your system.
120GB
250GB
It appears that TRIM is indeed working for both capacities, let’s dig into our testing.
ATTO Disk Benchmark is a relatively easy-to-use benchmark tool, which happens to be the benchmark of choice for many manufacturers. ATTO uses compressible data rather than random data, which results in higher performance and thus, higher benchmark scores. In our testing, we have selected the transfer size to range from 0.5KB to 8192KB, and have set the total length of the test to be 256MB.
120GB
250GB
Both drives perform very well in ATTO, reach up to 557MB/s read and 536MB/s write, both drives well exceeded the drive’s listed specifications (540MB/s read and 520MB/s write). We also see that a drastic increase in the performance curve around the 16 KB file size, where both drives almost reach 500 MB/s.
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.
It’s already available for consumers. You can buy it from ebay. (current price $75 for 250GB)
I got one yesterday. 250Gb; under $65 where I live.
nice bargain
I dont like having an ssd that dont compress as my main C drive. It’s fine for a dedicated game drive and such, but as a drive that houses Windows I would never use a Samsung drive. In just a month (after a clean install) Windows 10 and Chrome had written half a terabyte on my 850 evo and that’s just light usage. A controller that compresses all this junk, such as Sandforce, will have considerably lower writes on them. That’s a good thing.
I have used this drive on my i3 laptop and it can only reach 250 read and write due to it being sata 2
