Chap 5: Hard Drives

Chap 5: Magnetic HD

Chap 5: Solid State Drives

Chap 5: SSD

Chap 5: Hard Drive Interfaces 2.5'' (for laptops usually) 3.5'' PATA (older) 3.5'' SATA(newer)

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: PATA

Chap 5: SATA

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
