Intel 540s Series 240GB M.2 SATA SSD

The Intel 540s Series SSDSCKKW240H6X1 is a 240GB internal solid-state drive built in the M.2 2280 form factor with a SATA III interface. It uses 16nm TLC NAND and includes AES 256-bit hardware encryption for data security. This drive suits laptops or compact desktops where a low-profile SATA storage upgrade is required.

Thermals noise and power draw

With no moving parts the drive runs silently and produces minimal heat in everyday workloads. Power consumption is rated at 55mW during idle and 150mW when active, helping to extend battery life in mobile systems. The low-power design keeps thermal output modest inside tight chassis.

Upgrade path and value

The drive replaces a 2.5-inch SATA hard drive or an older SATA SSD, delivering sequential reads up to 560 MBps and writes up to 480 MBps. Random performance reaches 78000 IOPS read and 85000 IOPS write for snappier application loading. The jump is worth it when moving from mechanical storage or a lower-capacity SATA SSD to gain speed, silence and 240GB of space in an M.2 slot.

Questions about this item

How do I install the Intel 540s Series M.2 2280 240GB SATA SSD and what step is commonly missed?

Insert the drive into the M.2 slot at an angle, press flat, and secure with the retention screw. The step often missed is enabling SATA mode for the M.2 slot in BIOS, otherwise the drive will not appear.

What maintenance or replacement will the Intel 540s Series 240GB TLC SATA SSD need over its lifespan?

No mechanical maintenance is required. The 16nm TLC NAND has a finite write endurance; once the reserved spare blocks are exhausted the drive becomes read-only and must be replaced.

What limit appears first on the Intel 540s Series 240GB SATA SSD during sustained heavy writes?

The SATA III interface caps sequential write throughput at 480 MBps, so the bus saturates before the controller or NAND reaches its own thermal or performance ceiling.
