Definition:
A solid-state drive (SSD) is a data storage device that uses solid-state memory to store data persistently. Unlike traditional hard disk drives (HDDs), which use spinning disks and mechanical components, SSDs have no moving parts and store data on interconnected flash memory chips.
How SSDs Work
SSDs utilize flash memory, a type of non-volatile memory that retains data even when the device is powered off. Flash memory cells consist of floating gates that can hold one or more electrons. By applying different voltage levels to the gates, data is stored as a charge representing binary values.
Types of SSDs
Based on Interface:
| Type | Interface | Description |
|---|---|---|
| SATA SSD | Serial ATA | Uses the traditional SATA interface |
| NVMe SSD | Non-Volatile Memory Express | Direct connection to the motherboard via PCIe |
| M.2 SSD | M.2 Port | Compact and versatile form factor |
Based on Flash Memory Type:
| Type | Flash Memory | Description |
|---|---|---|
| SLC (Single-Level Cell) | Stores 1 bit per cell | High performance, but expensive |
| MLC (Multi-Level Cell) | Stores 2 bits per cell | Lower performance and durability than SLC |
| TLC (Triple-Level Cell) | Stores 3 bits per cell | Lowest performance and durability, but most cost-effective |
| QLC (Quad-Level Cell) | Stores 4 bits per cell | Even lower performance and durability than TLC |
