An SSD, or Solid-State Drive, is a type of storage device that uses integrated circuits to store data persistently. Unlike traditional Hard Disk Drives (HDDs), SSDs have no moving parts, which allows them to deliver faster data access speeds, reduced latency, increased resistance to physical shock, lower power consumption and silent operation. SSDs use flash memory to store data, with NAND flash being the most common type. SSDs are available in various form factors, including 2.5-inch, M.2, and U.2, to suit different devices and use cases. Common interfaces include SATA, PCIe, and NVMe.
Key features of SSDs include faster boot and load times, improved file transfer speeds, enhanced gaming experience, and noiseless operation. SSDs are generally more reliable and durable than HDDs due to the absence of moving parts. They are also more energy-efficient, leading to better battery life in laptops. Notable SSD manufacturers include Samsung, Western Digital, Crucial/Micron, Intel, and Kioxia. However, due to a global shortage of RAM and SSDs, driven by increased demand from AI data centers and enterprise systems, SSD prices have been rising sharply in 2026, with industry analysts projecting a 15-20% increase in overall PC pricing. This shortage is expected to continue through 2027. As of February 2026, the price of a 1TB SSD ranges from $119 to $201, depending on the brand and type.
