What Common Both Can Do?

Form factor: Both SSDs use the standard M.2 2280 form factor, ensuring compatibility with the vast majority of modern desktops and laptops. This makes installation straightforward without requiring adapters or special mounting hardware.
Interface type: Each drive connects via a PCIe x4 interface, allowing them to fully utilize multiple PCIe lanes for high data throughput. This shared interface standard ensures broad motherboard support across recent platforms.
NVMe support: Both models support the NVMe 2.0 specification, which improves command efficiency and latency compared to older storage protocols. This matters for faster boot times, quicker application launches, and smoother multitasking.
NAND technology: Samsung uses its own TLC V-NAND flash in both drives, balancing performance, endurance, and cost. TLC NAND provides strong sustained speeds while maintaining good write durability for everyday and professional workloads.
DRAM cache: Each SSD includes dedicated DRAM cache to store mapping tables. This improves random read and write performance and helps maintain consistent speeds under heavy workloads.
Hardware encryption: Both drives support AES 256-bit hardware encryption, enabling secure data protection without relying on software-based solutions. This is important for users handling sensitive or confidential data.
TCG Opal support: Support for TCG Opal allows both SSDs to integrate with enterprise-grade and OS-level encryption systems. This feature is useful for secure boot environments and managed systems.
IEEE 1667 support: Both models comply with IEEE 1667, enabling seamless compatibility with Microsoft eDrive and Windows BitLocker. This simplifies full-disk encryption setup for Windows users.
SMART support: Each SSD supports SMART monitoring, allowing users to track drive health, temperature, and remaining lifespan. This helps prevent unexpected data loss by identifying issues early.
TRIM support: TRIM support is present on both drives, helping the operating system inform the SSD which blocks are no longer in use. This maintains long-term performance and reduces unnecessary write amplification.
Garbage collection: Both SSDs use internal garbage collection to manage unused data blocks. This ensures consistent performance even after long periods of heavy use.
Samsung Magician support: Each drive is fully supported by Samsung Magician software for firmware updates, performance optimization, and health monitoring. This gives users centralized control and maintenance tools.
Over-provisioning support: Both SSDs allow user-defined over-provisioning to reserve extra NAND capacity. This can improve sustained performance and extend drive lifespan.
Wear-leveling: Advanced wear-leveling algorithms are used in both models to evenly distribute writes across NAND cells. This helps maximize endurance and reliability over time.
Thermal protection: Samsung’s Dynamic Thermal Guard technology is present in both drives to manage operating temperatures. This prevents thermal throttling and protects the SSD from heat-related damage.
Backward compatibility: Both SSDs are backward compatible with older PCIe generations. This allows them to function in a wide range of systems, even if full performance cannot be reached on older platforms.
Target usage: Samsung positions both drives for consumer and enthusiast use, including gaming, content creation, and high-performance computing tasks. This shared focus reflects similar expectations for reliability and premium performance.
