Kiintotiheysmuistit, known in English as Solid-State Drives (SSDs), are a type of data storage device that uses integrated circuit assemblies to store data persistently. Unlike traditional Hard Disk Drives (HDDs) which rely on spinning magnetic platters and moving read/write heads, SSDs have no moving mechanical parts. This fundamental difference contributes to their significant advantages in performance, durability, and power consumption.

The core components of an SSD are NAND flash memory chips and a controller. The NAND flash memory stores the data in electrical cells, and the controller manages data reading, writing, and error correction. Data is accessed electronically, allowing for much faster read and write speeds compared to HDDs. This speed translates to quicker boot times for operating systems, faster application loading, and improved overall system responsiveness.

SSDs are also more resistant to physical shock and vibration because of their lack of moving parts, making them ideal for laptops and portable devices. They consume less power than HDDs, leading to longer battery life in mobile computing. However, SSDs have historically had a higher cost per gigabyte compared to HDDs, although this gap has been narrowing over time. They also have a finite number of write cycles for each memory cell, a characteristic known as write endurance, though modern SSDs employ wear-leveling techniques to distribute writes evenly and extend their lifespan significantly.
