With an explosion in data and the relentless growth in demand for information, identifying a much more efficient means of storage has become extremely important. In this session, we will cover the key drivers behind the need for faster and more efficient storage. NVMe, a standardized protocol for PCIe-based storage, is giving users the huge leap in bandwidth required for demanding applications. Samsung, who makes the fastest NVMe SSDs on the market, will cover the benefits enabled by such technology, in areas such as fraud prevention and surgical procedures.
The technology behind flash drives – NAND memory – will be spotlighted in this presentation. Memory manufacturers have improved NAND’s value by migrating from single-level-cell to multi-level-cell designs, but the most significant evolution will be a marriage of triple-level-cell and V-NAND flash manufacturing technologies. Samsung will also provide an overview of the prospects for TLC V-NAND with mobile device manufacturers, while examining the strong potential for a much wider TLC V-NAND market in data centers.

48. V-NAND Gains Back What was Lost
For planar NAND, performance was sacrificed
going to TLC
V-NAND has faster program/erase than planar
V-NAND gains back what was lost
49. V-NAND Gains Back What was Lost
For planar NAND, endurance was sacrificed
going to TLC
V-NAND gains back what was lost
Industry transitioning to 3D NAND for
mainstream client and enterprise applications
50. How Does This Translate to SSD Performance?
Synthetic benchmarks show TLC V-NAND
SSD outperforms MLC SSD
51. How Does This Translate to SSD Performance?
Synthetic benchmarks show TLC V-NAND
SSD outperforms MLC SSD
Data Center use also requires great
random performance – TLC V-NAND holds
up well
52. Performance, Density, and Power
Endurance in SSDs can be tuned via
amount of Over Provisioning (OP)
55. Use in Client
Used in mainstream commercial
and consumer notebooks
Integrated in major OEM
designs, and sold in retail and
after-market channels
56. Use in Data Center
TLC V-NAND achieves the level
of performance and reliability
required
Enables a cost point ready to
displace 15K HDDs
