What are the two types of hard drives? Which is the most common?

Hard Disk Drive (HDD) and Solid State Drive (SSD). HDDs are the most common, but SSDs are quickly catching up.

Hard Disk Drive (HDD) and Solid State Drive (SSD). HDDs are the most common, but SSDs are quickly catching up.

What is the speed cap of SSD's theoretically? Realistically?

600 MBps, 550 MBps.

HDDs usually come in two common speeds. What are they?

5,400 rpm for laptops/consoles, 7,200 rpm for desktops.

What are the names of these cables?

What are the names of these cables?

PATA (or IDE) and SATA, respectively.

Why do SSD's last longer than HDD's?

SSD's don't have any moving parts to break.

What are two reasons one might choose an HDD over an SSD?

More storage, and they don't fail suddenly like SSD's do.

What is the theoretical max speed of SATA I? SATA II? SATA III?

150 MBps (1.5 Gbps), 300 MBps (3 Gbps), 600 MBps (6 Gbps).

What happens during hard drive defragmentation?

Rearranging data to group relevant things together, resulting in a faster drive.

Why should someone not defragment an SSD?

No performance gain, you'd just be wasting reads and writes.

What is RAID 0?

Data is split up, and saved across all drives. AKA striping. Minimum of 2 drives.

Data is split up, and saved across all drives. AKA striping. Minimum of 2 drives.

What is the benefit of RAID 0?

Increased read/write speeds, however there is no redundancy.

What is RAID 1?

Data is duplicated across all drives. AKA mirroring. Minimum of 2 drives.

Data is duplicated across all drives. AKA mirroring. Minimum of 2 drives.

What is the benefit of RAID 1?

24/7 backup, however there is no performance increase.

What is RAID 5?

Data is spread across all drives but one, and all backed up on the last one. AKA Striping with Parity. Minimum of 3 drives.

What are the benefits of RAID 5?

Increased read/write speeds, and redundancy.

What is RAID 10 (1+0)?

Half the data goes to 2 drives, the other half goes to the other 2 drives. AKA Mirroring with Striping. Minimum of 4 drives.

Half the data goes to 2 drives, the other half goes to the other 2 drives. AKA Mirroring with Striping. Minimum of 4 drives.

What are the benefits of RAID 10?

Increased read/write speeds, and redundancy.

What is shown here?

What is shown here?

A hard drive hot swap bay.

What is the default OS drive letter?

C. You can change it if you really want to, though it should be left alone for simplicity's sake.

What's the part of the drive that tells the motherboard where the operating system is?

MBR or GPT.

What does MBR stand for?

Master Boot Record.

What are the characteristics of MBR?

Supports up to 2 TB and up to 4 partitions per drive. Only stores the boot info on one sector.

What does GPT stand for?

GUID (Globally Unique IDentifier) Partition Table.

What are the characteristics of GPT?

Supports up to 9.4 billion TB and up to 128 partitions per drive. Stores the boot info on multiple sectors.

What is it called to clear all data from a drive?

Formatting.

What are the two types of formatting?

Quick and full.

What is a quick format?

All data is wiped, but no additional checks are run for bad sectors.

What is a full format?

All data is wiped, and written over with random 1s and 0s to prevent recovery. Checks are also run for bad sectors, and attempts to correct them.
