Samsung 850 PRO

As Samsung has accustomed us since the 820 series there are two versions: basic and with installation kit. In our case, we will analyze the input model without data migration software or extras apart from the disk. The packaging consists of a small cardboard box that incorporates the corporate colors: gray and white. On the back of the box we have the most important characteristics of the SSD and the mention of V-NAND technology. The bundle consists of the Samsung 850 PRO 128 GB Disc, CD with an installation guide and the necessary documentation to process the warranty.

It includes the normal dimensions of the SSDs of the last years with 2.5 inches. It is very well distinguished from the EVO line by the black color under the brand logo. At the time of installation we will have no problems, since as everyone has a maximum thickness of 7mm and is compatible with all laptops around the house or Macbook that use a SATA disk.

We are going to enter the technical specifications of this model; It incorporates second generation 40nm NAND 3D memory, a 1GB LPDDR2 chip to be used as a cache, and Samsung 's 3-core MEX controller. All this technology together gives us excellent sequential read and write rates of 550 MB / s and 470 MB / s respectively in the most basic model. If we choose one of his older brothers we will obtain 550 MB / s and 520 MB / s.

Test and performance equipment

TESTING BENCH
Processor:	Intel i7-4770k
Base plate:	Asus Z97 Pro Gamer
Memory:	8 GB DDR3 G.Skills Ripjaws 2400 Mhz.
Heatsink	Stock sink.
HDD	Samsung PRO 850 128GB SSD.

Power supply	Antec High Current Pro 850W

For the tests we will use the native controller of the z97 chipset on a high-performance board: Asus Z97 PRO Gamer that is within the reach of any pocket.

Our tests will be performed with the following performance software.

• Crystal Disk Mark. AS SSD Benchmark 1.7.4 ATTO Disk Benchmark

Highlight the significant efficiency of Samsung's garbage collection algorithm (one of the best today) and how well the cache works to dramatically improve the performance of flash memory.

Software: Samsung Magician

Samsung Magician is the utility that incorporates Samsung SSDs to optimize, diagnose if there is an error and monitor the solid state hard drive. It also allows us to perform cloning, backups, update SSD firmware without losing data and perform benchmarks. It is only applicable to Samsung units in both the 850 EVO / PRO series and earlier.

Final words and conclusion

Samsung is one of the best SSD manufacturers on the market for excellent read / write rates, durability, and aesthetics in its premium products.

In our performance tests they have matched the three programs we have used. Having the read and write rates (550 MB / s and 470 MB / s) promised by the manufacturer. In addition to including TRIM technology and its full compatibility with all SATA (I / II / III) ports on the market.

I would also like to highlight the Samsung Magician software that we can download from the manufacturer's own website. That allows us? Perform backups, cloning, firmware updates without losing the information on our disk and performance tests.

The Samsung 85o PRO 128GB is one of the best SSD we have tested so far, currently it is for a price that is close to € 100, for users who do not want to spend a lot and want to benefit from a 10-year warranty, without place This is undoubtedly the perfect SSD for your computer or laptop.
