What is an SSD?
An SSD, or solid-state drive, is a type of storage device that uses integrated circuit assemblies as memory to store data persistently. Unlike traditional hard disk drives (HDDs) that use spinning platters and a read/write head, SSDs store data electronically on flash memory chips. This fundamental difference leads to significant performance improvements.
- No Moving Parts: SSDs lack the mechanical components of HDDs, eliminating the seek time and rotational latency inherent in HDDs. This results in significantly faster access times. The absence of moving parts also makes SSDs more durable and resistant to damage from physical shock.
- Flash Memory: SSDs use flash memory, a type of non-volatile memory that retains its contents even when power is removed. This memory is organized in blocks, allowing for fast data reading and writing. Data is stored as electrical charges within the memory cells, unlike magnetic storage in HDDs.
- Interface Types: SSDs connect to the computer via various interfaces, most commonly SATA and NVMe. SATA is an older, slower interface, while NVMe is a faster, more modern interface specifically designed for SSDs. The choice of interface significantly impacts the SSD’s performance.
