1. Agenda
2. Introduction and purpose
• Hello my name is ____ and I would like to take you into a brief discussion about two different storage devices that are typically utilized on today’s computers.
• This topic is relevant to everyone here as each of you own or at least have utilized a computer. And in every functioning computer there is the data retaining device called a hard disk drive.
What is a (traditional) hard drive which is noted as a HDD?
• Hard disk drives are a storage type of device which up until recently, all computers have had a mechanical drive. This type of hard disk drive has a motor which turns magnetized platters of metal.
• The issue with today’s files is that they are getting very very large in size. Examples: Photos and Videos - say for instance a Blue ray movie, which can be 8GB. Mechanical drives are slow to move this large data.

What is a Solid State Drive or as commonly called, a SSD?
• A SSD is also a storage device but it has no moving parts at all. No motor or spinning platters
• They are very light and thin
• This drive has less than half the electrical current draw that HDD pull. How is that relevant to me you ask? It means the newest portable device’s battery can last ~80% longer (motors require more electricity). Ipads, Ipods and many other drives have form of SSD inside.

Okay – Not that that kind of Flash

Characteristics between a HDD and SDD
Compare and contrast
• Speed – HDD up to ~75MB/s sustained | SDD up to ~540MB/s sustained
• Current pricing - HDD - .07/GB | SSD - $.66/GB. A 128GB SSD is about $85 cost\drive size = .xx. This depends what size purchasing.
• Power – HDD 12 watts | SDD 2 watts

Speed Characteristics between a SDD and HDD
Compare and contrast
• A SDD really out shines a HDD with respect to access time. This is the time is takes for data to be retrieved.
