Samsung 840 Series 250GB SSD Review – The Worlds First TLC SSD Takes Center Stage

TEST BENCH AND PROTOCOL

Our analysis today will be conducted with our Asus Z77 Premium Test Bench.

In testing, our main objective is to obtain results as pure and as accurate as possible and we want to ensure that no anomalies slip through. Simply put, we want to provide you with the absolute best results the tested hardware can provide. Repetition in testing is standard and, if necessary, we may conduct specific tests in Windows 7 safe mode to ensure the OS has little to no influence on the end result.

In order to validate and confirm our findings, testing is supported by industry accepted benchmark programs. All results are displayed through capture of the actual benchmark for better understanding of the testing process by the reader.

We would like to thank ASUS (P8Z77-V Premium), Intel (Core i7-3770K), Crucial (Ballistix), Corsair (H100) and Be Quiet (PSU/Fans) for supporting the build of our Z77 Premium Test Bench.

BENCHMARK SOFTWARE

The software we will be using for today’s analysis is typical of many of our reviews and consists of ATTO Disk Benchmark, Crystal DiskMark, AS SSD, Anvil Storage Utilities and PCMark Vantage.  We rely on these as they each have a way of supporting one another yet, at the same time, adding a new performance benchmark to the total picture.  Much of the software is free and can be downloaded simply by clicking on the linked title.

SAMSUNGS NEW CONTROLLER

The new Samsung controller is a 3 core MDX device that operates on eight channels and has a model number of S4LNO21X01-8030. Here we have a bit of a close up view of the controller first hand:

CRYSTAL DISK INFO VER 3.9.3

Crystal Disk Info provides some excellent information about the SSD itself to include its health, product information, ‘power on’ information as well as the characteristics of the SSD. We can see that the SSD is capable of TRIM as it is not greyed out as with APM and AAM.

I especially like the image of the SSD standing on end among office buildings.

On page 8 , slight mistake in the title and the chart, we are testing the Samsung 840, not the 830. Awesome review though.

Thanks and that is actually an editorial trick! Now, we are certain that we have at least one reader and the article was a success. Fixed!

Really liked the review I also have a 128gb 840 pro and a 128gb 830 Samsung drives bought the 840 250gb set as my OS(windows 8) drive to see how it runs so far really impressed in real world use very similar to my 128gb 840pro better than the to crucial M4 128gb and 64gb I decided on smaller drives and I rotate them every few months. They all get a turn at running the OS spreads the writes around all the drives.
Samsung has good track record with SSDs so figured it was worth a try

Any thoughts of setting up an 8-drive RAID test on a nice LSI adapter???? I’d love to see how the Pro numbers scale up.

one of my bud works for a company that does the nand, he told me TLC are only around 1k write cycle. so basically 1/3 of the lower MLC and 1/5 of old MLC drives?

Except….the latest trend now is extending the life of such NAND and we are seeing through many different companies.
