Samsung 840 EVO 120GB SATA SSD
The Samsung 840 EVO is a 2.5-inch internal solid state drive with a 120GB capacity and a SATA III interface. It uses TLC memory and a Samsung MEX controller to deliver sustained sequential reads up to 540MB/s and writes up to 410MB/s. Random 4KB performance reaches 94,000 IOPS read and 35,000 IOPS write. The drive measures 7.11mm in height and 69.85mm in width.
Upgrading from a mechanical hard drive
Replacing a traditional hard drive with this SSD removes the mechanical latency that slows boot times and application launches. The jump is most noticeable when moving an operating system and frequently used programs onto the drive. For users storing large media libraries, the 120GB capacity may require a secondary drive for bulk data.
Simple 2.5-inch SATA installation
Installation follows the standard 2.5-inch SATA process: connect the drive to a free SATA data port and a SATA power connector, then secure it in a drive bay or bracket. The low 0.045W idle power draw reduces strain on the power supply. Common issues include forgetting to enable AHCI mode in the BIOS or leaving the drive uninitialised in the operating system disk manager.

Ερωτήσεις για αυτό το προϊόν
Will the 7.11 mm height fit my laptop 2.5 inch bay?
The drive is 7.11 mm tall and 69.85 mm wide, matching the standard 2.5 inch SATA form factor used in most laptops and desktops.
How do I install the MZ-7TE120BW and what step is often missed?
Connect the SATA data and power cables, secure the drive with four screws, then initialise and format the 120 GB volume in your OS before use.
When will the TLC NAND on this 840 EVO need replacement?
With a 1.5 million hour MTBF and 0.045 W idle power, the drive is rated for many years of typical client workloads before wear-out.
