Samsung presents its new SSD 850 Pro Series

After the success of the line of SSD 840, Samsung unveiled at this time the new 850 Pro Series with a dedicated event in Seoul. The first peculiarity of these models is that they exploit the memory with three-dimensional arrangement, or on layers of cells stacked vertically.

The V-NAND make improvements to energy consumption, for the occupation of space and performance, especially for the small cuts that are usually castrated than the more capacious models.

In this case, there is a distribution of less than 32 levels as a small skyscraper NAND, and it is a technology currently exclusive to Samsung and this specific model.

The company claims performance of up to 550 MB / s read and 520 MB / s write, also reached the 128GB model, and also a considerable increase in operations on the files small size (4K), with 100,000 read IOPS and 90,000 write IOPS. Recall that these are to provide the performance boost in daily life, most of the maximum speed that can only be achieved in the management of large files.

The heart of it all is the new controller MEX tri-core processor with 400MHz and 1GB of memory for the 1TB model (it is always 1% of the cut, so it will be 128MB for the 128GB).

Unfortunately, the interface remains the classic SATA 6 Gbps, which nowadays is the real obstacle to the performance of an SSD. It would be interesting to see this on-board memory of a product Express SATA interface (which supports up to 10 Gbps).

At the heart of the new family are a controller 850 PRO MEX three core frequency of 400 MHz, assisted by a maximum of 1 GB of LPDDR2 memory cache (1 MB cache per GB of capacity, so the 128 GB model has 128 MB cache, and so on).

The new proposals are equipped with Dynamic Thermal Guard, a technology that monitors the ambient temperature and prevents potential data loss from overheating. Do not miss the technology Self-Encrypting Drive (SED) for data encryption, support 256-bit AES hardware-standard Trusted Computing Group (TCG) Opal v2.0.

According to Samsung, the V-NAND memory can handle up to 80 GB of data written every day, which is equivalent to 150 Terabytes Written (TBW), or 150 terabytes written to the SSD before you have problems. And if you ever encounter various malfunctions, the 10-year warranty is a big help.
