Samsung MZ-7WD800EW 845DC Pro Series 800GB 2.5" 3D V-NAND Solid State Drive

Boost performance with an industry-leading 3D V-NAND SSD

The 845DC PRO is equipped with Samsung's cutting-edge 3D V-NAND flash memory, which is fabricated using an innovative vertical architecture, stacking 24 cell layers on top of one another rather than trying to decrease the cells' length and width to fit today's shrinking form factors. The result is higher density and higher performance using a smaller footprint and a breakthrough in overcoming the density limits of conventional planar NAND architecture.

Deliver highly optimized performance for various data center applications

In order to handle the critical demands of the data center environment, an SSD must maintain sustained performance over extended periods of time. The Samsung 845DC PRO is specially optimized to excel in virtually any data center scenario. This enterprise-level, ultra-high-performance SSD provides unsurpassed sustained random and sequential read/write performance, particularly suitable for write-intensive data center applications Using Samsung's innovative 3D V-NAND technology and its data center optimized MDX controller.

Obtain consistent performance with low latency

The MLC 3D V-NAND flash memory, when combined with Samsung's 3-core MDX controller, enables the 845DC PRO to deliver an exceptionally consistent level of input/output per second (IOPS) performance, as well as consistent I/O latency. When performance consistency is 99 percent in random read and 95 percent in random write. In addition, the 845DC PRO can be configured into various RAID levels based on performance needs, workloads and costs.

Advanced ECC engine and end-to-end data protection

Detect signal discrepancies and proactively remedy them in real time with the Error Correcting Code (ECC) engine. Implementing this process significantly improves the reliability of the SSD, thereby ensuring the integrity of the data read from each NAND chip. In addition, end-to-end data protection extends error detection throughout the entire path from the host interface to the NAND flash memory in the SSD. Specific algorithms monitor every endurance cycle and tune each cell for higher endurance as needed, while wear leveling and block replacements are managed proactively at the same time.

Power-loss protection

Protect data integrity from unexpected power loss with Samsung's advanced power-loss protection architecture. Using the electricity from a tantalum capacitor to provide enough time to transfer the cached data in the DRAM to the flash memory, you can be assured no loss of data.

S.M.A.R.T.

Monitor the computer drives proactively to detect and report various reliability indicators with Self-Monitoring, Analysis and Reporting Technology (S.M.A.R.T.). When a failure is anticipated, the S.M.A.R.T. warns the user of impending drive failure, giving the user time to replace the ailing drive, avoiding data loss from unforeseen outages.

Dynamic Thermal Guard protection

Safeguard the SSD from overheating by automatically controlling the speed of the CPU relative to its core temperature by throttling back the performance to prevent thermal shutdown.

Entrust your valuable data to Samsung's high-endurance 845DC PRO

Today's data centers are increasingly seeking higher write-endurance SSDs to meet skyrocketing computing capacity demands, from Big Data to virtual and cloud infrastructures. Because write-intensive operations place a burden on latency and consistency Quality of Service (QoS) over time, typically the lifespan of an SSD shortens. However, Samsung's 3D V-NAND Technology boasts incredibly high endurance levels - enabling the 845DC PRO to achieve 10 Drive Writes per Day (DWPD) over a five-year warranty period.
