960GB SATA III SSD for consumer systems

The Kingston A400 SA400S37/960G is a 2.5-inch internal solid-state drive built with 3D NAND and a SATA III interface. It delivers maximum sequential read speeds of 500 MBps and maximum sequential write speeds of 450 MBps. The drive is rated for an MTBF of 1,000,000 hours and draws 0.195W at idle. It suits desktops and notebooks that use a standard 7mm 2.5-inch bay.

HDD replacement upgrade for older machines

This SSD replaces a mechanical hard drive in systems that still run on SATA III, offering up to 10x faster start-up, loading and file transfers. The jump is worth it when boot times, application launches or large-file copies feel sluggish on a spinning disk. Shock and vibration resistance makes it reliable for notebooks that move frequently. Capacities of 120GB, 240GB, 480GB and 960GB cover a range of storage needs.

Practical limits of the SATA III interface

Sequential throughput tops out at the SATA III ceiling of roughly 500 MBps read and 450 MBps write, so the drive cannot exceed those figures regardless of NAND speed. Random 4KB performance reaches 400 megabits_per_second read and 500 megabits_per_second write, which is typical for the protocol. The 960GB cache allocation matches the full capacity, but the interface remains the bottleneck for sustained heavy workloads.

Questions about this item

Will the 2.5 inch 7mm form factor fit my laptop drive bay?

The drive uses a standard 2.5 inch SATA connector and a 7mm height, matching most laptop and desktop bays designed for 2.5 inch drives.

What is the correct cloning step when replacing my hard drive with this SSD?

Clone the old drive to the A400 while both are connected, then swap the physical drives and set the SSD as the primary boot device in BIOS.

How long is the drive rated to last under typical use?

The MTBF rating is 1,000,000 hours and the 3D NAND memory provides shock and vibration resistance for long-term reliability.
