CS 125 Busses
• Bus: Connection point to add stuff
• USB–1.1 vs. 2.0
• Firewire–400 vs. 800
• SATA – “Serial ATA”. Cheaper, faster than ATA/IDE for hard drives
• PATA (aka IDE/ATA) – internal drives
CS 125 Characteristics
• Hot Swappable• Easy Setup and Use• Newer **IS** backwards
compatible with older–Firewire 800 can use Firewire 400 gizmo
with an adaptor
• Don’t forget to “eject”!–Prevent headaches and data loss
CS 125 USB

• 1.1: 12 Mbits/sec
• 2.0:480 Mbits/sec

• FW400:400 Mbits/sec
• FW800:
• 800 Mbits/sec

CS 125 SATA
• 150 MB/sec & 300 MB/sec
• eSATA = external
• Primarily used for Hard Drives
CS 125 More SATA CablesIf Motherboard has a SATA port, and use this gizmo to make them externally accessible
CS 125 Hmmm……..
• Pop HD into port like Atari game cart
• Also has card reader, USB ports
• Connects to CPU via eSATA
• Handy if have hard drives sitting around
CS 125 External Enclosures
• Box that connects to machine
• YOU add a hard drive to it
• Pay attention to the connection types
• SATA – IDE/ATA – USB – FIREWIRE
• INTERNAL vs. EXTERNAL
CS 125 Examples
• External Enclosures
• Hard Drives
• Add-on cards
CS 125 Which to get?
• Get what your computer has
• Can add additional busses w/ expansion cards–Have to know what type of slots your
