Question

With so many different storage options, it would be helpful to be able to easily compare them all. In this activity, you’ll create a summary of the most commonly used storage devices. Choose at least three devices from the list below. CD DVD Blu-ray Disc Floppy Disk Internal Hard Disk External Hard Disk Flash drive (USB stick or memory card) Solid State Drive (Internal) Research the device further and take notes on the following: Method (optical, magnetic or solid state?) Capacity (how much can it store?) Speed Portability Durability and Reliability

answer shortly and correctly

Answer 1

Here's a summary of three commonly used storage devices:

### 1. **CD (Compact Disc)**
- **Method:** Optical
- **Capacity:** Approximately 700 MB
- **Speed:** Slower read/write speeds (up to 150 KB/s)
- **Portability:** Highly portable; lightweight and compact
- **Durability and Reliability:** Prone to scratches; relatively moderate reliability.

### 2. **External Hard Disk**
- **Method:** Magnetic
- **Capacity:** Ranges from 500 GB to several TB (terabytes)
- **Speed:** Generally faster than CDs; around 100-200 MB/s depending on connection type (USB, Thunderbolt)
- **Portability:** Portable, but can be bulky depending on size
- **Durability and Reliability:** Susceptible to physical damage; reliability can vary based on build quality.

### 3. **Solid State Drive (SSD)**
- **Method:** Solid State
- **Capacity:** Typically ranges from 120 GB to 8 TB or more
- **Speed:** Very fast read/write speeds (up to 5000 MB/s or higher for NVMe models)
- **Portability:** Highly portable, especially in 2.5-inch form factor
- **Durability and Reliability:** More durable than magnetic drives; no moving parts make them less prone to failure.

These summaries provide a quick comparison of the three selected storage devices based on key characteristics.
