Capacity and audience

This 500GB SATA internal SSD targets consumer workloads such as OS boot, application loading and everyday file storage. The 2.5 inch form factor fits standard laptop and desktop bays. V-NAND 3bit MLC memory and a Samsung MGX controller with 512MB DRAM cache handle mixed read and write traffic.

Sustained write behaviour

Sequential write reaches 520 MBps and 4KB random write hits 90,000 IOPS at queue depth 32. At low queue depth the drive still delivers 40,000 IOPS, so performance remains steady during extended copy jobs or background updates. The controller manages write amplification to keep throughput consistent over long sessions.

Thermals noise and power

Idle draw is 70mW while active use averages 3.1W with a 3.6W peak. The drive operates from 0°C to 70°C and survives storage from -40°C to 85°C. With no moving parts it produces no acoustic noise, making it suitable for quiet systems and mobile devices.
