Capacity and form factor

The Kingston A400 is a 240GB internal solid state drive built in the 2.5-inch, 7mm form factor. It targets desktop PCs, notebooks and all-in-one systems that need a straightforward storage upgrade. The drive uses a SATA III 6Gb/s interface and a Phison S11 controller with 3D TLC NAND. It is designed for plug-and-play installation in mainstream computers.

SATA III interface

The single specification that decides fit is the SATA III 6Gb/s interface with backward compatibility to SATA 2.0 and 1.0. Sequential reads reach up to 500MB/s and writes up to 350MB/s, while 4KB random reads hit 80,000 IOPS and writes 25,000 IOPS. Endurance is rated at 80TBW and the controller includes LDPC error correction. These figures define whether the drive matches the host system’s bandwidth and workload expectations.

Build integration

The drive connects through a standard SATA 7-pin data connector and a 15-pin power connector, requiring no extra cables or adapters beyond what a typical chassis provides. Active power draw is 1.5W typical and idle draw is 0.3W typical, freeing thermal headroom in compact builds. Shock resistance of 1500G and vibration resistance of 2.17G allow reliable operation in mobile or transportable systems. The mechanical-free design adds silent operation to any configuration.

Questions sur cet article

What does the 500MB/s read figure mean when the drive is installed in a laptop?

It is the maximum sequential read speed the drive can reach over the SATA III link; real-world boot and file-load times will be lower because the interface caps sustained throughput at 6Gb/s.

How does the SATA III 6Gb/s interface limit actual transfer rates?

The 6Gb/s bus tops out around 500MB/s, so the drive's rated 500MB/s read and 350MB/s write are already at the interface ceiling.

Will the 7mm 2.5-inch form factor fit my notebook's drive bay?

Yes, the drive is a standard 2.5-inch 7mm SATA SSD and uses the usual 7-pin data plus 15-pin power connectors found in most laptops and desktops.
