Kingston 2.5" 256GB SATA SSD

This internal solid-state drive fits standard 2.5-inch bays and connects through a SATA Rev. 3.0 interface with backwards compatibility to SATA Rev. 2.0. It is suited for upgrading laptops or desktops that still rely on mechanical hard drives. The Phison 3110 controller delivers sequential speeds up to 550 MB/s read and 540 MB/s write.

Upgrade from a mechanical hard drive

Replacing a spinning disk with this SSD removes the seek latency that slows boot times and application launches. The jump is worth it when the system feels sluggish during everyday tasks and the platform only offers SATA connectivity. Endurance is rated at 300 TBW or 0.65 DWPD for the 256GB capacity.

Simple 2.5-inch installation

The drive slides into any 2.5-inch bay and uses the same SATA data and power cables as a hard drive. No extra drivers are required on modern operating systems. Common issues include forgetting to enable AHCI mode in the BIOS or leaving the drive uninitialised in the OS disk manager.

Questions about this item

What size drive bay does the 2.5" SKC400S37/256G fit into?

It fits any standard 2.5" internal drive bay or caddy with SATA data and power connectors.

What is the most common mistake when installing this SATA SSD?

Connecting the SATA data cable but forgetting the separate SATA power cable from the PSU, so the drive never spins up.

When should I plan to replace the SKC400S37/256G based on its endurance rating?

The 256GB model is rated for 300 TBW or 0.65 DWPD, so replacement depends on how many terabytes you write each year.
