Samsung SSD 850 Pro 2.5 inch SATAIII

The next leading SSD for performance, endurance and energy efficiency.

  • The World's First Consumer 3D V-NAND SSD
  • Ultimate Read/Write Performance
  • Enhanced Endurance and Reliability
  • Efficient Power Management

Samsung SSD 850 Pro 2.5 inch SATAIII

The world's first 3D Vertical NAND (V-NAND) SSD- the Samsung SSD 850 Pro

The Samsung 850 PRO SSD redefines storage with the world’s first drive based on 3D VNAND flash, offering exceptional read/write performance, reliability and power management efficiency. The 850 Pro delivers up to 2x the speed, density and endurance of conventional flash. The next leading SSD for performance, endurance and energy efficiency.

What is V-NAND and how does it differ from existing technology?

Samsung's flash memory is fabricated using an innovative 3D V-NAND architecture, which stacks 32 cell layers on top of one another. The result is higher density and higher performance using a smaller footprint and a breakthrough in overcoming the density limits of conventional planar NAND.

An SSD that won't quit before you do

With twice the endurance of the previous model*, the 850 PRO will keep working as long as you do. Samsung's V-NAND technology is built to handle a minimum of 150 Terabytes Written (TBW) over the lifetime of the drive, which equates to a 40 GB daily read/write workload over a 10-year period. Plus, it comes with the industry's top-level ten-year limited warranty.

*840 PRO: 73 TBW > 850 PRO: 150 TBW.

Boost performance with an industry-leading 3D VNAND SSD

Powered by Samsung's cutting-edge 3D V-NAND technology, the NAND flash memory delivers class-leading read and write performance for both sequential and random workloads.

Work longer with high-efficiency innovation

The efficient design of the 850 PRO enables you work longer and more productively. Boasting the lowest power consumption of any SSD when in full use, the 850 PRO uses less energy (need source) while maintaining class-leading performance. The 850 PRO fully supports Device Sleep mode for Ultrabook, consuming only 2 milliwats (2mw) of power in its ultra low power state.

Plus, its low power DDR2 cache memory provides high performance while consuming up to 30 percent less power when active and up to 93 percent less power when idle than typical DDR2 or DDR3 memory.

Safeguard precious data without sacrificing performance

Protect your PCs hardware and personal data when you take your laptop on the road with the 850 PRO's Self-Encrypting Drive (SED) technology. The drive includes an AES-256-bit hardware-based, full disk encryption engine that secures your data without the performance loss often experienced with software-based encryption. The 850 PRO's advanced security complies with the TCG Opal v2.0 standard and is compatible with the Microsoft eDrive IEEE 1667 protocol. Plus, you can quickly erase data or sanitize your drive with the crypto erase feature.

Protect your PC from overheating with Dynamic Thermal Guard protection

The 850 PRO includes Dynamic Thermal Guard protection, which sustains performance while minimizing the risk of overheating. This feature monitors and maintains the drive's optimal operating temperature with a throttle feature that automatically drops the SSD's temperature to protect your data while ensuring the responsiveness you expect.

Award-Winning laurels for the Samsung 850 PRO.

5.0 out of 5 stars Parfait pour mon Latitude E4310
Reviewed in France on January 1, 2016
J'avais déjà un SSD sur mon Dell portable, monté d'origine. Je ne vais donc pas vous faire l'éloge de la montée en puissance et en rapidité d'un passage au HDD au SSD. Le fait est qu'à l'époque de mon achat, les SSD coutaient un bras et que je me contentais de 60 Go depuis longtemps pour mon OS et mes données perso, le tout sous Linux Ubuntu.
L'un de mes soucis, c'est que lors de l'installation d'Ubuntu, j'avais choisi de partitionner /home en plus du /swap. Ce qui était la meilleure solution en 2010, mais plus maintenant. Même si j'archive régulièrement mes données personnelles sur un autre disque (le disque dur en prod n'est pas un espace de stockage!), les deux partitions étaient remplies à plus de 80 %, ce qui n'est jamais conseillé en termes de performance.

Donc, j'ai pris du 128 Go SSD dans la série pro. Pour le même prix, j'aurais pu avoir 256 Go dans la série non pro (carré gris), mais la longévité du disque m'a semblé bien plus importante que la place, puisque, je le répète, un disque dur en production sur un ordinateur n'est pas un espace de stockage. Ce qui me double tout de même la capacité, tout en m'assurant à peu près de ne pas commencer à baliser sur la pérennité de mon disque dans 5 ans (temps moyen pour un SSD).

Niveau montage, j'ai été particulièrement surprise de voir que mon SSD d'origine n'était pas caréné : juste une petite plaque de circuit avec des mémoires flash collées dessus, le tout monté sur un châssis de métal.

Pour monter le nouveau disque, c'est plutôt simple, mais il faut faire attention, les disques SSD étant très fin, ils sont tendance à passer sous la map de raccordement au la carte mère. Il faut alors retourner l'ordinateur (position normale au lieu de sur le dos pour accéder à la trappe!) pour que le disque s'insère bien droit. La vis de fixation étant courte, si ça patine dans le vide, c'est que le SSD n'est pas mappé, il faut retourner et recommencer.

Une fois le disque bien inséré, c'est très facile : aller sur le BIOS au démarrage, demander à booter sur la clé USB bootable qui permet d'installer Ubuntu. Choisir l'installation par défaut, sur une seule partition (le /home sera quand même protégé en cas de réinstallation de l'OS). Ensuite, avec une dock station, on a copié le contenu de l'ancien /home du vieux disque sur le nouveau et c'est parti pour de longues années d'accès disque ultra rapide et de grande sobriété énergétique!
