250GB 850 EVO SSD 2.5" SATA 6Gbps 32 Layer 3D V-NAND Solid State Drive (MZ-75E250B/EU)Samsung’s unique and innovative 3D V-NAND flash memory architecture is a breakthrough in overcoming the density limitations, performance and endurance of today’s conventional planar NAND architecture. 3D VNAND is fabricated by stacking 32 cell layers vertically over one another rather than decreasing the cells dimensions and trying to fit itself onto a fixed horizontal space resulting in higher density and better performance utilizing a smaller footprint.
Optimized performance for everyday computing experiences
Powered by Samsung's cutting-edge 3D V-NAND technology, 850 EVO delivers top-class sequential
and random read and write performance to optimize everyday computing. With improved performance thanks to TurboWrite technology the 850 EVO provides not only more than a 10% better user experience than 840 EVO but up to 1.9x faster random write speeds for the 120/250 GB models as well. In fact, the 850 EVO delivers top class sequential read (540 MB/s) and write (520 MB/s) performance in all capacities. This comes with optimized random read and write performance on all QD and improved QD1 and QD2 random performance for Client PC usage.
Reinforcement of TurboWrite Technology
In the early stages of the 840 EVO, Samsung adopted sequential write performance first. With
TurboWrite, write speeds are significantly accelerated during data transfers by creating a high-performance write buffer in the SSD. If a consecutive write operation (i.e. no idle time) exceeds the size of the buffer, the transfer will exit TurboWrite and be processed at ”After TurboWrite” speeds. Once the buffer is cleared, TurboWrite performance will resume. However, the buffer size for TurboWrite is more than sufficient for everyday PC use, and you should experience accelerated speeds for most workloads.
Guaranteed endurance and reliability for maximum use
The 850 EVO delivers guaranteed endurance and reliability by doubling the TBW compared to the
previous generation 840 EVO backed by an industry leading 5 year warranty. With twice the endurance of a typical NAND flash SSD, the 850 EVO will keep working as long as you do. The 850 EVO guarantees a 5 year limited warranty or 75TBW for 120GB and 250GB, 150TBW for 500GB and 1TB.
Enhanced reliability with improved sustained performance
With enhanced reliability through improved sustained performance, the 850 EVO assures longterm
dependable performance up to 30% longer than the 840 EVO with minimized performance degradation. This means you can use it every day when taking care of work or entertaining yourself knowing it will keep performing even with heavy daily workloads over the years.
Advanced data encryption
The 850 EVO provides the same data encryption feature as the 840 EVO does. Self-Encrypting Drive
(SED) security technology will help keep data safe at all times. It includes an AES 256-bit hardwarebased
encryption engine to ensure that your personal files remain secure. Being hardwarebased, the encryption engine secures your data without performance degradation that you may experience with a software-based encryption. Also, 850 EVO is compliant with advanced security management solutions (TCG Opal and IEEE 1667). Magician will guide ”How to use security features”. Furthermore, you can erase or initialize data with the crypto erase service with PSID.
Efficient power management for all PC applications
Power consumption affects everyone. You actually save of up to 50% more on power than with the 840 EVO during write operations thanks to 3D V-NAND consuming half the power of 2D planar NAND.
Whether it’s preserving battery life for longer cordless use or just saving on costs, power management is important. Device sleep signals the SSD to enter a low power state which is vital for ultra-books and other battery powered devices. With 850 EVO’s Device Sleep at a highly efficient 2mW you get longer battery life on your notebook thanks to a controller optimized for 3D V-NAND. With the 850 EVO you can work and play longer without having to plug in.
