2.5-inch SATA SSD for everyday builds

The Mushkin Enhanced Source MKNSSDSR250GB is a 250GB internal solid-state drive that fits standard 2.5-inch bays and connects through a SATA interface. It uses 3D TLC NAND with a Silicon Motion SM2258XT controller to deliver reliable storage for consumer desktops and laptops.

Low power draw and quiet operation

With no moving parts the drive runs silently and stays within a 0°C to 70°C operating range. Idle power consumption is 0.08W and active consumption reaches 2W, keeping heat output minimal inside compact chassis.

560 MBps sequential read speed defines upgrade

Rated at up to 560 MBps read and 515 MBps write, the drive saturates the SATA III link and provides a clear speed boost over mechanical disks for boot, application load and file transfer tasks.

Questions about this item

How do I install this 2.5" SATA III SSD in a laptop, and which step often trips people up?

Mount the 7 mm drive in the 2.5" bay, connect the SATA data and power cables, then enable AHCI in BIOS before cloning or installing the OS; skipping AHCI leaves the drive running in legacy IDE mode and cuts the 560 MBps read / 515 MBps write potential.

What maintenance or replacement will this MKNSSDSR250GB need over its life?

No mechanical parts require service; firmware is user-upgradeable for bug fixes, and the 1 500 000-hour MTBF with global wear-levelling and StaticDataRefresh means the 3D TLC NAND typically outlasts the host system.

What limit appears first when I hammer this 250 GB drive with sustained writes?

The SLC cache absorbs bursts, but once exhausted the 3D TLC native write speed drops below the 515 MBps peak, and the 2 W active power envelope can trigger thermal throttling at the 70 °C operating ceiling.
