Increase energy efficiency while avoiding drive wear and tear
Samsung's flash-based SSDs help maintain 24 x 7 uptime for mission-critical servers, RAID systems, and network-attached storage. For mobile devices, Samsung SSDs offer small form factor and light weight, together with low power consumption in active and idle modes to lengthen battery life. Because SSDs have no moving parts, they start up instantly and are not subject to the physical wear and tear that can gradually degrade the reliability of traditional hard disk drives.
Design advantages of Samsung SSDs include:
- Accelerated read and write operations with outstanding multitasking capabilities
- Varied interfaces enabling connections to different types of host devices
- Exceptional durability with high shock and vibration tolerance
Samsung maintains outstanding quality control over the design and production of its SSDs, from NAND flash and DRAM components to controllers and firmware. Samsung's leadership in the SSD market is a direct result of unmatched expertise in semiconductor technology, along with our demonstrated ability to design and develop memory solutions in-house.
Breaking the Barriers: Data Center MLC-class SSD High-Performance,
Consistently Low Latency and Extreme Write Endurance
Today, more and more data centers are embracing extremely fast, energy-efficient IT systems and system components, to better support the client and server markets, along with the virtual and cloud enterprise infrastructure behind them.
IT management are driving today's business transformation initiatives, Big Data systems, VDI and other high-performance enterprise platforms in cloud infrastructures, rack-designed systems and virtualized environments. Increasingly, investments in solid state drive (SSD) technology are streamlining storage and computing capacity in the data center.
Samsung has released SM843T and SV843 SSDs, utilizing MLC NAND Flash, which feature consistently low latency, highlevel of sustained writes (IOPS), high-write endurance, coupled with power-loss protection-all at capacities up to 960GB.
Samsung SM843T/SV843 Raise the Bar on Data Center SSDs
Here are more details about this new drive's outstanding features:
Exceptional Low Latency and a Workhorse of a Drive
Unlike conventional SSDs in their category, which provide very good performance at the onset, as more write operations are made to other SSDs, the latency and QoS typically suffer. On the other hand, Samsung's SM843T and SV843 SSDs deliver an exceptionally consistent level of performance (99.9% of reads at 170µs) over the life of the SSD at the same price category as other consumer-based MLC-based offerings.
The Samsung SM843T and SV843 are optimized for sustained random read and write workloads (89,000 IOPS/14,000 IOPS).
The life of a drive is generally determined by such factors as the type of applications and workloads that are being used. The Samsung SM843T is optimized for random write workloads up to 1.8 full drive writes per day (WPD) and up to 3.6 WPD with the SV843 SSD which represents a 12x improvement over competitive offerings.
Enterprise Power-Loss Protection
Samsung SM843T and SV843 SSDs are built with tantalum capacitors to protect all of your data in write cache in the case of a power failure. This enterprise-grade power-loss protection provides an added level of security to ensure that valuable write information is well protected against data corruption caused by power-loss.
High-Capacity SSDs Available
Samsung SM843T and SV843 SSDs are available in several densities, allowing you to maximize your capacity with the same number of drive slots. The drive processes 14,000 IOPS on writes all the way up to 960GB-over 7x the density over a 128GB SSD.
