2. SQL Server 2008 & Solid State Drives ► Why SSD ?  Weight  Space  Power consumption  DC event horizon  Durability  Less equipment to manage  Less downtime  IOPS – SPEED !

3. SQL Server 2008 & Solid State Drives ► Myths  They don’t last long

4. SQL Server 2008 & Solid State Drives ► 20Gb backup ► ioDrive filled to 97% full before backup ► Repeatedly written into same space ► 2,000 x = over 5 years daily backups ► Slow down after 4.5 years ► BUT – no wear load balancing ► Still longer than a typical hard disk
