Samsung Electronics is working on a new solid-state drive with 4TB capacity. The SSD will be available in early 2016, but its performance and pricing are yet unknown.

Samsung 850 Pro solid-state drive with 4TB capacity will be based on the company’s third-generation 48-layer 3D V-NAND memory, reports AnandTech. While exact performance of the Samsung 850 Pro 4TB SSD is unknown, expect it to be a little lower compared to performance of other drives in the series. Since the SSDs come in 2.5” form-factor and use Serial ATA-6Gb/s interface, the 850 Pro-series solid-state drives are not really performance champions in general.

Solid-state drives with 4TB capacity will help Samsung to better compete against other makers of SSDs. The unique consumer solid-state drives will be exclusively available only from Samsung for quite a while.

4TB SSDs will provide HDD-class capacity, but expect such devices to be very expensive. Even though NAND flash memory is rather affordable today, 4TB of memory cost a lot of money.

KitGuru Says: A 4TB SSD for consumers is clearly a unique product. Nonetheless, do not expect it to be truly fast since it will be based on 48-layer 3D V-NAND, which is slower than the company's second-gen 3D V-NAND memory used on 850 Pro SSDs today.

Samsung Electronics has introduced its all-new solid-state drives based on the latest TLC 3D V-NAND flash memory for enterprises. The SSDs provide unprecedented levels of performance, capacity, endurance and reliability, which will help Samsung to address new markets.

The new enterprise-class SSDs are based on Samsung’s latest 48-layer 3D V-NAND triple-level-cell (TLC) memory and Samsung’s proprietary controller and firmware. The new drives support NVMe protocol, protection against power loss as well as other advanced features required by datacentres.

The new flagship Samsung PM1725 enterprise-class solid-state drives come in half-height, half-length (HHHL) card form-factor with PCI Express 3.0 x8 interface with NVMe protocol. The drives can store 3.2TB or 6.4TB of data and provides outstanding reliability with five DWPDs (drive writes per day) for five years, which translates to writing a total of 32TBs per day during that time.

Performance levels of the Samsung PM1725 are also unprecedented: the SSDs can sequentially read data at up to 5500MB/s and write data at up to 1800MB/s. The PM1725 provides a random read speed of up to one million IOPS (input output operations per second) and writes randomly at up to 120 thousand IOPS.

In addition, Samsung introduced PM1633 solid-state drives, which come in 2.5” form-factor and feature serial attached SCSI-12Gb/s (SAS-12Gb/s) interface. The PM1633 delivers random read and write speeds of up to 160 thousand and 18 thousand IOPS respectively, and boasts sequential read and write speeds of up to 1100MB/s and 1000MB/s. The new drives will be available in 480GB, 960GB, 1.92TB and 3.84TB versions.

“We are providing high-end capabilities and capacities for all of our latest SSDs, something we believe will elicit a high degree of interest from OEMs and computer enthusiasts throughout the world,” said Jim Elliott, corporate vice president of Samsung Semiconductor. “We understand the performance needs of our customers in a rapidly expanding SSD universe and are determined to meet those needs.”

KitGuru Says: Without any doubts, Samsung’s new PM1725 and PM1633 are nothing, but remarkable. What is even more impressive is that 48-layer TLC 3D V-NAND memory is among the cheapest NAND flash options in the industry. In short, Samsung has just managed to create ultra-premium SSDs using inexpensive NAND.

Samsung Electronics on Tuesday said that it had started to mass produce the world’s first triple-level-cell (TLC) three dimensional vertical NAND flash memory chips with 256Gb capacity. The new 3D V-NAND memory ICs [integrated circuits] will help Samsung to make solid-state drives and other flash-based devices more affordable, which will help to increase market share of the company.

The new 256Gb TLC NAND flash memory chips from Samsung utilize the same 3D charge trap flash (CTF) architecture in which the cell arrays are stacked vertically to form a 48-storied mass that is electrically connected through some 1.8 billion channel holes punching through the arrays thanks to a special etching technology. In total, each chip contains over 85.3 billion cells and can store 32GB of data.

According to Samsung, the new 48-layer 256Gb TLC NAND flash memory chip consumes 30 per cent less energy than the predecessor, which has 128Gb capacity. The new chip is also 40 per cent smaller than its ancestor, which means that it costs less to produce.

“With the introduction of our 3rd generation V-NAND flash memory to the global market, we can now provide the best advanced memory solutions, with even higher efficiency based on improved performance, power utilization and manufacturing productivity, thereby accelerating growth of the high-performance and the high-density SSD markets,” said Young-Hyun Jun, president of the memory business at Samsung Electronics. “By making full use of Samsung V-NAND’s excellent features, we will expand our premium-level business in the enterprise and data center market segments, as well as in the consumer market, while continuing to strengthen our strategic SSD focus.”

Samsung hopes that its third-generation 3D V-NAND memory enable it to make affordable 1TB and 2TB solid-state drives for consumers. In addition, the company believes that such memory will help to increase its high-density SSD sales for the enterprise and data center storage markets with PCIe NVMe and SAS interfaces.

KitGuru Says: Samsung is again ahead of its rivals with its third-generation 3D V-NAND flash memory. It remains to be seen how significantly the company will manage to increase its share on the market of SSDs thanks to its new memory chips. At present the company controls over 40 per cent of the SSD market, according to analysts.
