Enterprise SATA SSD

The Intel DC S3500 SSDSC2BB120G401 is a 2.5-inch enterprise solid-state drive built for servers and storage arrays that require consistent SATA 3.0 performance. Its MLC flash and 2,000,000-hour MTBF suit read-heavy workloads such as web serving, caching or boot volumes where reliability matters more than peak throughput.

MLC endurance and power profile

MLC memory provides higher write endurance than consumer-grade TLC, extending service life under sustained mixed workloads. Active power draw of 2.3W and idle draw of 0.8W keep thermal load low in dense drive bays, while 1,000 G shock resistance protects data during rack maintenance.

120GB capacity ceiling

At 120GB the drive comfortably holds an OS, hypervisor or small database index with headroom for wear levelling. Sequential writes top out at 135 MBps and random writes at 4,600 IOPS, so heavy logging or large ingest jobs will saturate the controller quickly. Buyers needing larger volumes or higher sustained write bandwidth should look beyond this capacity point.

Questions about this item

How long is the drive rated to run before it needs replacement?

The drive carries a 2,000,000 hour MTBF rating, indicating the expected operational lifespan before failure risk rises.

What limits sustained write performance on this drive?

Sequential write tops out at 135 MBps and 4 KB random write at 4,600 IOPS, so the controller and MLC flash set the ceiling.

How much power does it draw and how hot does it get when running all day?

Active power is 2.3 W, idle is 0.8 W, and the operating temperature range is 0 °C to 70 °C.
