1 Bringing Greater Efficiency to the Enterprise Arena Solid State Drive Samsung Semiconductor Inc. Tony CES 2011 Flash Flash CES Memory 2011 Storage Solutions

2 What is SSD? Solid State Drive is a large capacity of storage using NAND Flash Memory as its media For interface wise, SSD is using S-ATA/SAS/FC interface for compatibility to legacy industry and also considering PCIe interface for lower latency

3 Hardware : SSD vs. HDD SDRAM SSD doesn t have mechanical component Head, Head platter, platter motor Read-channel, Preamp SSD does need FTL(Flash Transition Layer) More PCB layers for better SI/PI control Media PreAmp SOC NAND NAND NAND NAND NAND NAND NAND SOC NAND Read-Channel Hard Disk Controller Spindle motor VCM COMBO SATA

5 Enterprise SSD Market Forecast Enterprise SSD Market is still Emerging Status Enterprise SSD shipment is under 10% of total SSD market but revenue is over 30% of total SSD market SSD Total Shipment SSD Total Revenue 72M 7.2M $3.5B Storage Storage Server Server $2.3B 3.9M $1.6B 0.6M 1.1M 2.1M $0.7B $1.1B Source: Gartner Q4 10

6 Flash Memory Transforming Industries What can Flash do for the Enterprise System?

7 SSD Application Server and Storage Enterprise SSD Usage on a range of fields In Cache Server Cache Hit Cache Cache Miss storage For Streaming As Storage Too many things to find I need flash.. Bigger density on same price reducing cache miss ratio Lower latency than HDD Sustained Performance for stable service High Random IOPS for more many users High IOPS & Bandwidth Low Power Consumption Better TCO in IOPS/Watt

8 SSD Application - Datacenter Major 3 benefits of SSD in datacenter Less Power SSD consumes less power due to no mechanical part SSD has high power efficiency because of high performance Datacenter reduces power consumption enhancing service Less Cooling SSD emits lower heat because of no moving part SSD operates in higher temperature band Datacenter decreases cooling cost despite of more work Less Space SSD outperforms HDD over 100 times SSD treats t more much data due to high h performance Datacenter works more without additional warehouse

9 Environmental : HDD vs. SSD High Reliability / High Roughness / No Acoustic due to simple and strong composition Environmental Spec NAND flash Controller Connector HDD vs. SSD Shock 60G vs 1500G Vibration 0.5G vs 20G Acoustics 3.1bels vs 0bels Source: Available datasheet t *G : gravity *bel : sound power
