Intel SSD DC S3500 400GB SATA

The Intel SSD DC S3500 Series is a 400GB internal solid state drive built for data-centre workloads. It uses 20nm MLC NAND and a SATA III interface to deliver consistent read and write performance. The drive targets servers and storage arrays that need dependable endurance and full data-path protection. Power-loss protection and memory ECC help safeguard data during unexpected outages.

Upgrading from hard drives or entry-level SSDs

Replacing mechanical drives with this SSD removes rotational latency and raises sustained sequential reads to 500MBps and writes to 380MBps. Random 4KB reads reach 75,000 IOPS while writes hit 11,000 IOPS, cutting queue depth in transactional workloads. The jump is worth it when latency must drop below 65us and annualised failure rates need the 2,000,000-hour MTBF baseline. Standard endurance ratings back the transition for write-heavy applications.

400GB capacity with 450TB written endurance

The 400GB capacity comfortably handles operating-system volumes, logging partitions and caching tiers that stay within the 450TB lifetime write budget. Active power draw sits at 4.5W and idle at 0.6W, keeping thermal load low in dense enclosures. Operating temperatures from 0°C to 70°C and 1,000 G shock resistance give headroom for rack environments. Workloads that exceed the endurance ceiling or demand higher random write IOPS will need a larger or higher-tier drive.
