SATASSDlevyjä

SATASSDlevyjä is the Finnish term for SATA solid-state drives, referring to storage devices that use flash memory and the Serial ATA interface. The name is formed from SATA (Serial ATA) and SSD (solid-state drive) with the Finnish plural suffix -levyjä. In common usage the term denotes consumer and enterprise SATA SSDs rather than other SSD variants.

SATA SSDs store data in NAND flash memory and use the SATA bus to communicate with a host computer. They offer faster random access and lower latency than traditional spinning hard drives, while consuming less power and producing less heat.

The SATA III interface provides theoretical throughput of up to 6 Gbit/s, equating to about 550 MB/s in real-world sequential transfers. Real-world speeds vary by controller and NAND type; older drives and low-end models may be slower. Random I/O performance is higher than HDDs but typically lower than PCIe NVMe drives.

The common 2.5-inch form factor with a 7 mm or 9.5 mm height is typical. Some drives use mSATA or M.2 form factors with a SATA interface. They require a SATA host interface and power connector and are compatible with most desktops and laptops that include SATA ports.

SATA SSDs have widely replaced HDDs for many desktops, laptops, and servers due to performance and reliability, although PCIe NVMe drives now offer higher speeds. Leading manufacturers include Samsung, Crucial, Western Digital, and Kingston.
