A 120GB mSATA internal SSD with SATA III interface delivering up to 540MB/s sequential read and 410MB/s sequential write speeds
The Samsung 840 EVO MZ-MTE120BW is a 120GB internal SSD built for consumer devices that accept the mSATA form factor. It uses TLC memory and a Samsung MEX controller on a SATA III interface to deliver solid-state responsiveness in space-constrained notebooks or small form-factor PCs.
With no moving parts the drive runs completely silent and draws only 0.055W at idle and 0.145W during active use. It is rated to operate between 0°C and 70°C with humidity tolerance from 5% to 95%, so thermals stay manageable in tight chassis without additional cooling.
The board measures 3.8mm high, 30.0mm wide and 50.8mm deep, matching the mSATA specification for direct installation in compatible sockets. Rated at 1,500,000 hours MTBF, the drive is designed for long-term reliability in everyday consumer workloads.

Insert the MZ-MTE120BW into the mSATA slot at a slight angle, press down, and secure it with the retention screw; the step often missed is fastening that screw, which keeps the drive from lifting under vibration.
The Samsung MEX controller handles wear-leveling and TRIM automatically, so no user maintenance is required; replacement is only needed if the 1,500,000-hour MTBF is exceeded or the drive reaches its write endurance limit.
The sequential write speed caps at 410MB/s, and the TLC NAND’s slower program cycles become the bottleneck before the SATA III interface or the 0.145W active power draw does.
