  • 1,000,000 hour MTBF signals long-term reliability

Capacity and interface

The Kingston A400 240GB drive uses a 2.5 inch SATA form factor and 3D NAND flash memory. It targets users who want faster boot and load times on systems limited to the SATA interface. The lack of a DRAM cache is offset by host memory buffer support for everyday responsiveness.

Sustained load behaviour

Sequential write speeds reach 350 MBps while reads peak at 500 MBps, and the controller maintains these rates across typical consumer workloads. Average active power stays at 0.279 W with a maximum write draw of 1.535 W, so thermal output remains low inside cramped notebook chassis. The drive operates reliably from 0 °C to 70 °C and endures 2.17 G vibration while running.

Upgrade context

It replaces any 2.5 inch mechanical hard drive up to 960 GB, delivering roughly ten times the speed for start-up, file transfers and application launches. The jump is most worthwhile when reviving an older laptop or desktop that cannot accept newer interfaces but still has a SATA bay. Shock resistance of 20 G while powered off adds durability for mobile use.

Perguntas sobre este artigo

How much power does the A400 240GB draw during all-day operation?

The drive averages 0.279W active and peaks at 1.535W during write bursts, while idle power is only 0.195W. With no moving parts it runs silently and stays within the 0°C to 70°C operating range.

What connector and bay does the SA400S37/240G need to work?

It requires a standard SATA III data cable and a SATA power connector from the host, plus a 2.5" drive bay or bracket. No extra drivers are needed for Windows, Linux or macOS.

Will this 2.5" SATA SSD work in an older laptop that still uses a mechanical hard drive?

Yes. The SATA III interface is backward compatible with SATA II and SATA I ports, so the drive will function in legacy notebooks and desktops, delivering up to 500MB/s read and 350MB/s write where the link allows.
