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

SSD COMPONENTS

Our sample Samsung 840 SSD was 250GB and Samsung raves that it is perhaps the only completely proprietary SSD on the market where all of the units components are manufactured by Samsung.  It contains the new Samsung 3-core eight channel MDX controller (300MHz).

Just above the controller is Samsung’s 512MB DRAM cache memory with eight modules of Samsung’s new 21nm TLC DDR-2 toggle mode NAND (400Mbps), each with a capacity of 32GB. Final formatted capacity for the 250GB version of the 840 is 233GB of available user space.  The other side of the PCB does not contain any components.

To add to it’s list of features, the 840 has full TRIM support, garbage collection, S.M.A.R.T., AES 256-Bit Full Disk Encryption, an operating temperature of -55 to 90DegC and can risk shock up to 1500G’

SAMSUNG SSD MAGICIAN

Although we had a fairly decent look at Ver. 4 beta version of the Samsung Magician at the Samsung 2012 SSD Summit, a current version (3.2) was found on the DVD and is still the most encompassing SSD tool package found anywhere.

To start, System Information provides a good look at your system hardware and software and the Performance Benchmark gives us our first look at what the 840 is capable of.

From there, Performance Optimization fine tunes your SSD and, once complete, will run right into a new benchmark test.  OS Optimization provides some useful SSD optimization tips and can be set to occur automatically or manually.  Such things as shutting down Superfetch, Defragmentation Schedule, ReadyBoost and Indexing are great support for our SSD Optimization Guide that has long been the most popular SSD optimization resource on the internet for years now.

F/W Update will automatically check and install any needed updates and, for those who need the added security performance boost over time, Secure Erase can be utilized to return your SSD to it’s factory fresh state.  I will concede that I am not a lover of Secure Erase as there have simply been to many SSD deaths in past history for too little performance gain.   We did do a Secure Erase of this new drive and all went well.

Something Samsung alone has enabled for consumers is the ability to manually configure their own over provisioning for their needs.  This is all topped off with Disk Cloning and complimentary software downloadable right from the Samsung SSD Magician such as Norrton Ghost.

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.
