Review: Samsung 840 EVO mSATA 250GB Reviewed by: Wendy Robertson Provided by:  Samsung Model: MZ-MTE250 Firmware version: EXT41B6Q


Samsung have taken the 840 EVO making it available in the much smaller mSATA form factor. There are few motherboards available which already have an mSATA slot available, but it is most likely that the 840 EVO mSATA SSD is aimed at the Ultrabook and laptop market. The Samsung 840 EVO mSATA utilises the now familiar Samsung MEX SSD controller, coupled with 19nm toggle 2 TLC NAND.

Samsung was kind enough to send me two SSDs for review. A 250GB model, and the world's first 1TB mSATA SSD. In this article I will be taking a look at the 250GB model, having covered the 1000GB model last week.

So let's find out how this new SSD performs in our range of tests.

Samsung company information

Samsung should need no introduction, but those of you who would like to find out more about Samsung, can do so at their website.

Now it’s time to take a look at the drive itself and what it came shipped with.


The review sample I received was the full retail kit.

The full retail kit contained the following items. The Samsung 840 EVO mSATA SSD itself, a couple of 'Samsung SSD activated' stickers, and an instruction and warranty information booklet.

The software supplied, via download from the Samsung website, is as follows.

  • Samsung Magician 4.3
  • Samsung Migration software (not shown or tested)

Samsung Magician

The Samsung Magician software allows the user to maintain the SSD, and has the following features.

  • Disk drive: Brings up useful information about the SSD, including its health status, and how much data has been written to the SSD.
  • System info: Allows the user to see system and drive properties.
  • Performance Benchmark: Performs a basic benchmark on the SSD.
  • Performance optimization: Performs a manual TRIM of the SSD.
  • OS Optimization: Allows operating system features, that can affect SSD performance, to be switched on or off.
  • Firmware Update: Allows the Samsung 840 EVO mSATA firmware to be updated.
  • Secure Erase: Sends a Secure Erase command to the SSD, clearing all NAND and returning the SSD back to its default factory state.
  • Over Provisioning: Allows the user to set aside a given amount of NAND as a manual over provisioning area.
  • SSD authenticity test: Checks to make sure that the SSD is a genuine Samsung SSD.
  • Enable Rapid mode: Enables the NVELO 'Rapid' cache feature.
  • Data Security: Applying 256-bit AES keys, the new self encryption feature allows strong data security, and is compliant with TCG Opal and IEEE 1667 standards.
