A superb SSD designed and engineered for data center use
Exceptional performance and high endurance especially designed for demanding data centers
Data centers have unique requirements to ensure they operate at optimal performance levels 24/7, 365 days a year. Consistent performance with low latency is essential as well as maintaining optimal stability when processing various read and write workloads. And most crucial of all is protection from exposure to data corruption or loss caused by unexpected power outages.
As a leader in high-end memory technology, Samsung is equipped to offer data centers superb solid state drives (SSDs) that deliver exceptional performance in write-intensive applications, such as mail servers, data warehousing and high-performance computing (HPC). These high-quality SSDs also deliver outstanding reliability and high endurance for continual operation regardless of power losses. Using its proven expertise and wealth of knowledge in cutting-edge SSD technology, Samsung had engineered the SSD 845DC PRO specifically for data center applications. Its revolutionary 3D Vertical-NAND (V-NAND) flash memory and the inclusion of an optimized controller, brings you uncompromising performance, superb reliability and high endurance.
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.
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.
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.
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.
Obtain consistent performance with low latency
It is essential to data center storage to limit the percentage of response times falling below a given value to maintain Quality of Service (QoS), which is measured by the consistency of steady performance the device delivers. Also of key importance in satisfying QoS requirements is low latency. Low latency is defined by how long it takes for a request to complete its round-trip cycle and measured by a single input/output (I/O) request on sequential and random workloads respectively. Cloud data centers, in particular, must be cognizant of QoS, as they are expected to provide the level of performance guaranteed by a Service Level Agreement (SLA) through parallel and real-time processing.
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.
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.
