CRYSTAL DISK BENCHMARK VER. 5.1.0 x64
Crystal Disk Benchmark is visually straightforward, and is used for measuring the speeds at which your storage device reads and writes in both compressible (oFill/1Fill) and random, mostly incompressible, data. Random data is more consistent with everyday use of a computer, such as transferring videos, pictures and music. We run the benchmark twice, using oFill data first, and then proceeding to test with random data. Since results typically return with nearly identical scores, we only include the results for random data samples.
120GB
250GB
Both drives again exceed the listed specifications when benchmarking in Crystal Disk Mark. The 250GB capacity reaches up to 525 MB/s in sequential write and 544 MB/s in sequential read. The 4K QD1 write performance is half decent, reaching up to 149 MB/s.
AS SSD Benchmark uses incompressible data in their testing of SSDs, essentially providing results that would be consistent with using the heaviest workload, thus lower speeds are expected. Transfer speeds (MB/s) are seen in the left picture below and IOPS (Input/Output Operations Per Second) are on the right.
120GB
250GB
When comparing the performance of both capacities, we see that the 250GB capacity has a slight advantage over the 120GB capacity, as it is faster in terms of both read and write sequential performance. The 120GB produced a total score of 1014, where the 250GB was also just ahead with 1119, both of these score are very respectable given their low value, entry level client SSD purpose. During the copy benchmark, both drives again performed respectively well considering their given purpose.
ANVIL STORAGE UTILITIES PROFESSIONAL (BETA)
Anvil Storage Utilities is essentially an all-in-one tool for all of your SSD benchmarking needs. Anvil can be used for basic consumer testing, as well as endurance testing and threaded I/O read, write and mixed tests. It displays data regarding the SSD, and even about your system.

250GB
Overall, Anvil returns with results very similar to what we have seen previously, with both drives achieving just over 520MB/s in sequential read tests and 500MB/s in sequential write tests. Both also achieve very respectable score of 5,291 and 5,379 for the 120GB and 250GB capacities accordingly.
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
