The Samsung 750 EVO (120GB & 250GB) SSD Review: A Return To Planar NAND
by Billy Tallis on April 22, 2016 8:00 AM ESTAnandTech Storage Bench - The Destroyer
The Destroyer is an extremely long test replicating the access patterns of very IO-intensive desktop usage. A detailed breakdown can be found in this article. Like real-world usage and unlike our Iometer tests, the drives do get the occasional break that allows for some background garbage collection and flushing caches, but those idle times are limited to 25ms so that it doesn't take all week to run the test.
We quantify performance on this test by reporting the drive's average data throughput, a few data points about its latency, and the total energy used by the drive over the course of the test.
The Destroyer has earned its name here. The 750 EVO is clearly the slowest modern SSD on this test, showing that it is not suitable for sustained intense workloads with a high volume of writes. Almost any other SSD currently on the market will perform better under pressure, including competing TLC drives.
The 750 EVO also sets new records for slow responses, with average service times on par with standard hard drive seek times. Though since The Destroyer has an average queue depth of about 5.5, a mechanical hard drive would still be several times worse by this metric. Conversely, the best MLC SSDs are almost ten times quicker than the 750 EVO.
With over 10% of operations taking more than 10ms, we can't quite refer to them as outliers anymore. At the 100ms threshold, the 750 EVO has twice as many outliers as anything else.
The substantially higher energy usage of the 750 EVOs is a straightforward consequence of them taking much longer than everything else to complete the test: The 120GB 750 EVO took just over 17 hours to complete this test while the 120GB PNY CS1311 took only 13.5 hours and the 128GB 850 Pro needed only 10 hours.

8$ is just too little of a difference and will not make a difference in a build as such.. I only see this as being implemented in finished machines from manufacturers, so that they can pop another 8$ in their pocket. Aftermarket.. Doubt it will sell a lot.Maybe i would use it in a HTPC, since it's not something that requires a lot of R/W operations once it's booted up

I noticed PNY & OCZ BENCHED IN THE MIDDLE, Sammy on the bottom [loser]Ahmad kassem - Sunday, May 1, 2016 - link
Is it ok to make more than one partition on this ssd or any other ssd?wayneclaassen - Thursday, May 5, 2016 - link
Well I needless to say I found the Samsung EVO 250GIG extremely reliable although it is a bit expensive, but for anyone that mostly run high performance graphics this price tag shouldn't be a big problem.Bulat Ziganshin - Saturday, May 7, 2016 - link
1. 750 may be a hit for developing markets. in particular i've seen 750 reviews on russian sites much earlier than here:fcenter/online/hardarticles/hdd/38770-Samsung_SSD_zadeshevo_obzor_Samsung_650_i_Samsung_750_EVO
2. Can you please add to your reviews checks of gc/trim effect and slc cache size as in the section

Billy, when you guys run the benchmarks, are the Samsung Evo drives run with RAPID Mode on or off? Just out of curiosity, as I am looking to buy the 850 Evo and I'd like to know if I can expect this sort of performance without having to turn on RAPID Mode. Thanks!jason_brody - Thursday, July 7, 2016 - link
Can anyone help if I should go with this SSD or 850 series for my Dell E6500?elzafir - Tuesday, April 11, 2017 - link
The 250GB 840 EVO is $15 cheaper where I live compared to the 750 EVO of the same size. Which one should I get?Manisthisunreal - Friday, October 13, 2017 - link
Notice because of all the fatmouths saying they'll "wait until it is cheaper" the industry has now colluded to up the prices and make up some bs excuses of "low demand" "commodity trader speculation on minerals". Yes we can blame stock traders for a lot of things like high oil prices, high wheat and other food goods prices but come on I smell something fishy. I was about to buy a 250gb Samsung SSD on black Friday for $60 almost two years ago when some idiot shopper woman decided to merge into me when I was on my way home from work leading to a 15 month nightmare. I never did make it out to get my ssd. Fast forward almost 2 years later and they've doubled in price. I really wanted that.
