Why Solid State Disks?Drives are getting Bigger not Faster

• 1956 RAMAC• 1956 RAMAC– The first hard disk drive

5 MB t– 5 MB storage– 1,200 RPM

• 2008 – 1 TB storageg– 15,000 RPM

• From 1956 to 2007:From 1956 to 2007:– 12.5 times increase in RPM

200 000 times increase in capacity– 200,000 times increase in capacity

How do disks Arrays try to solve performance issues?

M i A f Di k• Massive Arrays of Disks:

• This only ensures that access time doesn’t degrade y gbelow the 5 - 10 ms Access time, and that parallel operations can be handled.

• Can Solve: IO per second problems, Bandwidth problems

• Does not solve latency problems

Solid State Disks: A New optionSolid State Disks: A New option

Dramatically lower response time• Dramatically lower response time• Extremely high IOPS and Bandwidth

N diff i f f d ti l• No difference in performance for random or sequential performance.
