Solid State Drive (SSD)

Definition: A storage device that uses flash memory chips (instead of spinning disks) to store data permanently.

Technology:

No moving parts (unlike HDDs).

Uses NAND flash memory.


Speed:

Much faster than HDDs in boot time, file transfer, and application loading.

Lower latency and quicker access time.


Durability:

More resistant to shock, vibration, and physical damage since no mechanical parts.


Noise & Heat:

Completely silent and generates less heat.


Capacity:

Available from a few hundred GB to several TB, but usually smaller capacity than HDDs at the same price.


Cost:

More expensive per GB compared to HDDs.


Lifespan:

Limited number of write/erase cycles, but modern SSDs are reliable and long-lasting.


Form Factors:

2.5-inch SATA SSD (common for laptops/desktops).

M.2 SSD (small, thin module).

NVMe SSD (fastest, connected via PCIe).

Advantages:

Faster performance

Lower power consumption (good for laptops)

Durable and lightweight

Disadvantages:

Higher cost

Smaller storage compared to HDDs at the same price.
