SSD Market Forecast

SSD : The Fastest Growing application in NAND (CAGR 54%)

[SSD Bit shipment FCST]

Server & Storage (CAGR : 88%)

PC Client (CAGR : 40%)

- Read-intensive segment is growing rapidly

. More Applications are adopting Read-intensive SSD’s

- Low endurance & High density SAS with better TCO

. $/GB of 15K/10K SAS HDD ≈ $/GB of SAS SSD (3DWPD & below)

- High performance of PCIe SSD in Skylake will

boost SSD Attachment

. 2015, 20% → 2016, 28% → 2017, 35%

- Average Capacity is growing

. 2015, 239GB → 2016, 253GB → 2017, 318GB
