Chap 5: Hard Drive Considerations

Capacity: How many GB/TB?

Spindle speed: 7200RPM? 10000RPM?

Cache/Buffer: How many Mbs?

Interface standard: PATA? SATA? SCSI? USB?

Chap 5: RAID Not RAID - Spanning or JBOD

RAID 0 – Striping

RAID 1 – Mirroring

RAID 5 – Striping with parity (3 Disks minimum)

RAID 10 (1+0) – Striping and Mirroring (4 Disk minimum)

RAID takes special hardware or software. Windows has RAID support in software, but it would be better to use RAID hardware.

Chap 5: Tape Backups

Can hold tons of data and are very inexpensive!

Can be very slow

6 TB for $30

Chap 6: Supporting Input/Output

BASIC PRINCIPLES:

Devices are controlled by software

Some devices need special applications

A device cannot be fast that the port it is in

Problems can be solved by updating driver

Sometimes

Install only one device at a time

Chap 6: USB connections

There's a lot of em. There will be a really cool picture here when this slide is ready. The picture will show all the different USB connectors. It's so cool. But this slide isn't ready yet. Instead, here's link to me playing the saxophone:
