The 840 EVO mSATA comes in a small black and grey box. While there aren't a lot of details on the front, the back of the box lists some of the drive's key features. Inside, you'll find the SSD, user manual and warranty statement and a couple of "Samsung SSD Activated" stickers for your computer's case.
Physical Features:
The 840 EVO mSATA follows the JEDEC MO-300 standard for mSATA SSDs. It measures a mere 50.8 x 29.8 x 3.6 mm and is about one quarter the size of a standard 2.5-inch drive. The 840 EVO mSATA also has a 52-pin mSATA connector which supports data transfer rates up to 6 Gb/s.
Like the 840 EVO, the SSD 840 EVO uses Samsung's own S4LN045X01-8030 controller chip. Developed entirely in house, this proprietary, triple-core MEX controller excels at multi-tasking. Based on an ARM Cortex R4 (400MHz) controller, its three CPU cores can execute multiple instructions such as reading data, writing data and optimization.
For the 1TB version of the 840 EVO mSATA, Samsung used their own 19nm K9DMGY8SCM-DCK0 Toggle Mode MLC NAND flash. Looking at the pictures above, you can see that there are two of these 256GB flash memory packages on either side of the PCB. The drive also has a single 1GB K4P8G304EB-FGC2 LPDDR2 DRAM memory chip that is used for caching.
