Use PCIe 4.0 Performance Where Your System Supports It The PCIe 4.0 x4 interface and NVMe 2.0 protocol provide a high-bandwidth connection between the SSD and a compatible computer.

Support File Transfers with Intelligent TurboWrite Samsung measures the advertised sequential and random write performance with Intelligent TurboWrite active.

TRIM requires operating-system support. Together, these features give you useful tools for managing an everyday client-PC drive through its working life. Check the Slot and Mounting Before Installation The M.2 2280 module needs a compatible M-Key PCIe NVMe slot and suitable mounting space. An M.2 connector alone does not establish compatibility: a SATA-only connection is unsuitable. Check the computer or motherboard manual for the supported interface and module length. An installation kit is not supplied, so confirm that the host has the required fixing hardware before you begin. Plan Airflow for Sustained Work Samsung recommends proper airflow around the SSD. Adequate airflow helps the SSD operate within its specified temperature range, particularly during heavy transfers or when nearby components warm the drive.

Available features depend on the operating system, connection and software requirements. Check the current installation guidance before moving an existing system, keep a separate copy of important files and verify the replacement drive before relying on it for everyday work. Set Up Security and Understand Warranty Coverage The 990 supports AES 256-bit full-disk encryption, TCG Opal and IEEE 1667 encrypted-drive functions.

Performance uses Samsung IOmeter 1.1.0 with the SSD as a secondary drive in a fan-cooled desktop. Published writes use Intelligent TurboWrite within its supported transfer window. Firmware, host and workload affect results. Power consumption also depends on the host configuration and supported power states.
1GB means 1 billion bytes; formatted usable capacity is lower. MTBF is a statistical population rating, not a guaranteed individual lifespan. Samsung Magician internal-SSD health checks, firmware updates and data migration require supported Windows; other features vary by OS, connection and product. Country-of-purchase and manufacturer warranty terms apply.
