10 SSD Innovative Design Small Form Factor SSD, such as msata, will fit in the Slim Note PC or Media Tablet PC SSD F/F flexibility helps designers innovate system design Thickness( (mm) 25.4 (Lenovo X300) 19.3 (Apple Mac Air) 13.3 (Sony VAIO X) 9.99 With Case: 2.5-7mmT (Dell Adamo XPS)? Without Case: msata mmT Time

11 SSD Application - Client SSD-O system in Laptop PC and Dual drive in Desktop PC Thinner/Lighter/Faster laptops SSD is needed SSD for OS + main app. program and data archive for HDD Perfo ormance / Featu ures Netbook Dual Drive 250/500GB HDD 32/64GB SSD Consumer Cost Fighters Small Capacity SSD Commercial PC - For SMB - Replacing DT Consumer My Main PC Optional SSD Business Thin & Light Enterprise-Class Specialties Consumer Thin & Light Fashion Leader SSD Only Price

12 SSD Application Server and Storage Enterprise SSD Usages In Cache server Cache Heat 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 TOC in IOPS/Watt

13 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 more much data due to high performance Datacenter works more without additional warehouse

14 Tech Trend: Sustained Performance Push for sustained performance Sustained performance means supporting stable service without fluctuation FW optimization, over-provisioning and super-cap technology keep improving end user experiences by enabling sustained performance Eco-system (OS, File system) is being optimized for SSD Before After FW optimize

15 Tech Trend: Performance Throttling Performance Throttling technology could be utilized for differing i lifetime expectations ti from various customers Static performance throttling Dynamic performance throttling Static Performance Throttling Dynamic Performance Throttling Peak Performance Target Performance for 5yrs Perform mance Static Performance Perform mance Dynamic performance in real usage Usage[Year] Usage[Year]

16 Tech Trend: High Performance NAND Step 1 : Performance improvement with toggle mode NAND NAND Interface Speed : 66Mbps 133Mbps 400Mbps Random Read (IOPS) Random Write (IOPS) 10% 20% 40% 60% 66Mbps SDR 133Mbps DDR 400Mbps DDR 66Mbps SDR 133Mbps DDR 400Mbps DDR Step 2 : Low power consumption with low power NAND IO operating voltage(v ccq ) : 3.3V 1.8V Step 3 : Enterprise MLC into SSD with extended P/E cycles

17 Tech Trend : Enterprise SSD Trend Emerging MLC SSD into Enterprise industry SLC SSD for High Performance Computing MLC SSD for Main volume business with cost effectiveness SLC/MLC SSD Positioning in Enterprise Market OLTP Storage DSS HPC Web base Streaming SLC SSD SLC SSD MLC SSD SLC SSD MLC SSD

18 Tech Trend : Infra Collision System infra has been fit to HDD so that SSD has infra collision i with current infra For instance, current RAID/HBA controller cannot show full SSD performance due to hardware limit Need close work with RAID/HBA vendors to maximize SSD performance IOP PS Q1 SSD performance with various RAID/HBA controller Q4 Q16 Queue Depth Q64 A B C D E F
