Architektura V-NAND

Incredible performance by the SSD Samsung 850 Pro

The Samsung SSD 850 Pro is based on the technologically advanced 3D V-NAND architecture to achieve maximum read and write speeds in sequential and random access. Its layered cell architecture stacks cells vertically instead of side by side.

The result is a higher density and better performance in a smaller footprint, breaking through the limitations of conventional planar NAND architecture. Having doubled the cell endurance compared to the previous model, V-NAND technology can reliably handle 150TB (TBW), which is equivalent to 40GB per day for 10 years. Samsung has so much confidence in this SSD that it provides a 10-year warranty.

There are three reasons to buy this product.

RAPID mode

You can increase the read/write performance when you need it with Samsung RAPID mode. Just like shifting gears in a car, the Magician software gives you the option to enhance performance by processing data using unused PC memory (DRAM) as a cache, providing 1.8 times faster performance in RAPID mode.

  1. Breakthrough 3D V-NAND flash memory architecture.
  2. RAPID mode increases read/write speeds.
  3. Above-standard 10-year warranty.
  4. Advanced AES 256-bit encryption.
  5. Capacity of 256GB.

SSD Samsung

Only admiration

The 850 PRO includes Dynamic Thermal Guard protection, which sustains performance while minimising the risk of overheating. This feature monitors and maintains the drive's optimal operating temperature with a feature that, if necessary, automatically throttles the SSD temperature to protect your data.

This is the best SSD in the market. I just bought this one to upgrade from Samsung 840 pro 128GB. The only reason i decided to upgrade is because my old SSD storage space was not enough. But i still have it and it is in perfect condition after 5 Years. So for me it was a no brainer to buy from Samsung again. Quality is top, Speed is absolutely unparalleled. If you have enough RAM installed, i recommend activating, Rapid Mode. It multiplies the speed of your SSD, by using approximately 1.3 GB of your RAM as part of the SSD. In the 840 Pro i had it active for 5 years and had no problems. Also had active, the over provisioning and reliability mode. Right now the Benchmark from my computer returns - Sequential (MB/S): Read= 5251, Write= 4490 and - Random (IOPS): Read= 142254, Write= 109978. Insane I KNOW! If you can live with the price, then this is simply the best.

Good at maintaining IO speed after continous usage

Really good compared to a normal hard drive, specially the 256 does not get warm at all, so really good for normal users! Although it works perfectly, its not connectable to a PCIe, so i prefer the later added M.2 SSD for the faster reading and writing times.

Along with SSD and RAM 2x4GB probably have done the maximum upgrade of the HP ProBook 4740s Old HDD (Hitachi 500 gigabytes) in box is used as a replacement for the CD drive. RAM Ramík on the old HDD ib-ac642-d339109.htm
