Kingston SSDNow KC300 240GB SATA Enterprise SSD

The Kingston SSDNow KC300 is a 2.5-inch SATA III solid-state drive with 240GB capacity, built for enterprise workloads. It delivers sequential reads up to 540MB/s and writes up to 510MB/s, with random 4KB performance of 84,000 read IOPS and 52,000 write IOPS. A 1,000,000-hour MTBF and DuraClass data integrity protection underline its durability focus.

Suits servers and storage arrays needing reliable

This drive fits 2.5-inch SATA bays in servers, workstations or notebooks where consistent enterprise-grade endurance is required. Advanced power management keeps idle draw at 0.6W and active draw at 1.4W, helping battery-powered systems. Builders who need a different physical interface, higher capacity, or non-SATA protocol should consider other options.

SATA III interface and 2.5-inch form factor decide

The drive connects exclusively through a SATA III 6Gb/s interface and uses a standard 2.5-inch, 7.00mm-high form factor. Verify that the target system provides a SATA data and power connection and can accommodate the 69.8mm by 100.1mm footprint before purchase.

Questions about this item

How fast will the 540MB/s sequential read feel when the drive is installed in a server?

The 540MB/s sequential read is the SATA III interface ceiling, so large file transfers and boot sequences will run at that limit rather than the drive's internal maximum.

What does the SATA III interface mean for real-world throughput on this KC300?

SATA III caps at 6Gbps, so the published 540MB/s read and 510MB/s write are the practical maximums you will see in any compatible system.

Will the 7mm height fit my 2.5-inch drive bay without extra brackets?

The drive measures 7.00mm high, 69.8mm wide and 100.1mm deep, matching the standard 2.5-inch form factor used in most server and laptop bays.
