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. |
|
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? |
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. |
|
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. |
|
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. |
|
What are the benefits of RAID 10? |
Increased read/write speeds, and redundancy. |
|
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. |
