Samsung has launched the mass production of the first on the market SSDs ​​based on 3-bit NAND technology.

New storage devices (PM853T SSD) are designed primarily for servers used for social networking sites, web browsing, email, etc.

The new PM853T SSDs are introduced in densities of 240GB, 480GB and 960GB.  The Serial ATA 3.0 interface with the bandwidth of up to 6Gb/s serves as a connection to a computer.

Applying Samsung’s 10 nanometer (nm) 3-bit NAND flash components and updated  controller technology, the new drive shows  a sequential read speed of 530 megabytes per second (MB/s), while writing sequentially at  420MB/s. It also will read data randomly at 90,000 IOPS and handle sustained writes at 14,000 IOPS.

According to a forecast from IHS iSuppli, the global market volume of SSDs on the global market will be increased by a third this year compared to 2013 - from $ 9.4 to $ 12.4 billion. In 2017 it is expected to reach $ 20 billion.

HGST, division of  Western Digital, has announced that now they supply hard-disk drives MegaScale DC 4000.B. These drives of 3.5 inches in size with 4TB capacity are equipped with the SATA 6 Gb / s. They belong to the drives MegaScale of the second generation. According to the manufacturer and taking into consideration users’ feedback, they have further improved the balance between capacity, speed, reliability and power consumption.

In multilevel data storage systems drives MegaScale DC 4000.B are allocated for the storage of large volumes of unstructured data, backup "disk drive", the creation of online archives, long-term storage of data and other tasks, where important parameters are such as unit cost and energy intensity per unit volume.

According to HGST, drives MegaScale DC 4000.B with a spindle speed determined by the CoolSpin technology, are suitable for continuous operation under a load corresponding to rerecording of 180 TB a year. In comparison, high-performance drives Ultrastar 7K4000 with a spindle speed of 7200 rev / min RPM are designed for load of 550 TB a year.

They are designed for Cloud storage, "Video on Demand" and other applications where the combination of high performance, reliability, and storage density is crucial. These drives are characterized by the highest in the industry mean time between failure  - 2 million hours. In the case of MegaScale DC 4000.B drives mean time between failure is estimated at 800 thousand hours.
