Samsung Showcases Industry-leading Flash Technologies to Address Growing Requirements of Storage Systems
At Flash Memory Summit 2016, held in the Santa Clara (CA) Convention Center, Samsung showcased its 4th generation Vertical NAND (V-NAND) and a line-up of high-performance, high-capacity solid state drives (SSDs) available for its enterprise customers as well as Z-SSD, a new solution providing breakthrough performance for flash-based storage.

Samsung’s 4th Generation V-NAND Stacks 30 Percent More Layers of Cell-Arrays than its Predecessor
Samsung introduced its 4th generation, 64-layer triple-level-cell V-NAND flash memory that pushes the envelope of NAND scaling, performance and storage capacity. Stacking 64 layers of cell-arrays, the new V-NAND can increase its single-die density to an industry-leading 512Gb and its IO speed to 800Mbps, which further distinguishes Samsung’s technology leadership in three-dimensional NAND cell structure design and production.

Samsung plans to provide the world’s first 4th generation V-NAND flash memory products in the fourth quarter of this year, which will help manufacturers to produce faster, more stylish and portable computing devices, while offering consumers a more responsive computing environment.


World Largest Capacity Drive − 32TB SAS SSD − for Enterprise Storage Systems
Samsung’s latest Serial Attached SCSI (SAS) SSD is the world largest single drive ever introduced to the industry based on 512-gigabit (Gb) V-NAND chips. A total of 512 V-NAND chips are stacked in 16 layers to form a 1-terabyte (TB) package and the 32-terabyte (TB) SSD contains 32 of those packages.

By adopting a new 4th generation V-NAND design, the 32TB SAS SSD can reduce system space requirements up to 40 times compared with the same type of system using two racks of hard disk drives (HDDs). The 32TB SAS SSD will come in a 2-5-inch form factor and be produced in 2017.


New ‘Z- SSD’ Breaks through Performance Limits of Current NAND Flash Memory Storage
Samsung has also developed a high performance, ultra-low latency SSD solution, the Z-SSD. Samsung’s Z-SSD shares the fundamental structure of V-NAND and has a unique circuit design and controller that can maximize performance, with four times faster latency and 1.6 times better sequential reading than the Samsung PM963 NVMe SSD.

The Z-SSD will be used in systems that deal with extremely intensive real-time analysis as well as extending high performance to all types of workloads. It is expected to be released next year.

That was certainly a whole set of interesting announcements.

Right after Seagate reveal their 60TB SSD. Depending on the price and performance the Seagate one could very well be the better buy.

2.5" vs 3.5" form factors though. But I don't know if that's of great importance in enterprise.

3.5" is fine for desktops....i mean they're still smaller than the average component that most of us buy here...gfx cards.

For the industry, I believe Samsung might well be the better choice for a good few reasons. Their lead in 3D NAND is still unparalleled.

I don't think price necessarily matters much with the aim directly squared towards the enterprise industry on both the Seagate & Samsung side, I believe Samsung could cut the price too since they not only appear to have the benefit of higher production capacity but the fact all elements of their product is sourced from within Samsung itself with no premium if they'd had to obtain parts from other sellers, as Seagate has to (unsure on what or where they're sourcing the controller they're using, the NAND is sourced from Micron whom I imagine would sell it at a premium). Samsung can cut certain corners and has an inherent familiarity with their NAND products along with all the other components being developed in-house too.

From what I can work out, Seagate would have to use Intel-Micron 32-layer 384Gbit dies to form the packages considering a comment Seagate made about the density over the competition (which was invalidated by Samsung just now). Those 32-layer 384Gbit dies use a more traditional floating gate approach versus Samsung's charge trapping layer approach. It should inherently make it more reliable with Samsung, which I think would be an important factor.

What are you talking about? Apples vs oranges.

You can't stack the seagate PCIE card in a datacenter. The 2.5 SAS drive on the other hand will fit perfectly.

The seagate card is a raid 0 meant purely for performance without any redundancy. The SAS card is perfect for servers which has several drives for redundancy and performance, and for datacenters in which you can stick 20-30 or more of those drives, getting both performance and redundancy if one fails.
If just one of the 4 internal chips in the seagate fails, the whole card is dead.

He's referring to the newly announced Seagate 60TB 3.5" SAS SSD smile.gif
