2.5" 120GB SATA III Enterprise SSD

The Kingston SSDNow KC300 SKC300S37A/120G is a 2.5-inch solid-state drive with a 120GB capacity and a SATA III interface. It delivers sequential read speeds up to 540MB/s and write speeds up to 510MB/s. Random read performance reaches 17,000 IOPS while random write reaches 64,000 IOPS. The drive is rated for 1,000,000 hours MTBF and includes an adapter.

Suits servers and notebooks needing SATA reliability

This drive fits systems requiring a 2.5-inch SATA III drive with low power draw of 1.4W active and 0.6W idle. Advanced Power Management extends battery life during typical sessions. DuraClass technology and RAISE error reduction protect data integrity. Builders needing capacities beyond 120GB or interfaces other than SATA III should consider different drives.

Sequential read up to 540MB/s

The maximum sequential read speed of 540MB/s defines the throughput ceiling for large file transfers and boot operations. Sequential write reaches 510MB/s. Random 4KB read and write IOPS of 17,000 and 64,000 respectively determine responsiveness for transactional workloads. Operating temperature ranges from 0°C to 70°C.

Questions about this item

Will the 7.00mm height fit my 2.5" drive bay?

Yes, the 7.00mm profile matches the standard 2.5" SATA form factor used in most laptops and servers.

What is the common mistake when connecting the SATA III interface?

Forgetting to attach both the data cable and the power connector; the drive needs both to be recognised.

When should I plan to replace this 120GB drive based on its MTBF?

The 1,000,000-hour MTBF indicates a very long service life; monitor SMART attributes for wear instead of using a fixed schedule.
