Samsung 840 EVO 120GB SATA SSD

The Samsung 840 EVO MZ-7TE120BW is a 120GB internal solid state drive built for everyday computing. It uses a 2.5 inch form factor and a SATA interface to replace mechanical hard drives in laptops and desktops. The drive suits users who want faster boot times and application loading without changing platform infrastructure.

Fits standard 2.5 inch SATA bays

The drive slots into any 2.5 inch bay with a SATA III connection and requires no additional drivers or cables beyond the standard data and power leads. Its 7.11mm height matches typical laptop caddies and desktop brackets. Low idle power draw of 0.045W helps extend battery life in portable systems while freeing thermal headroom for other components.

120GB capacity for OS and core apps

The 120GB TLC volume comfortably holds an operating system, core productivity suite and a handful of frequently used programs. Sequential reads up to 540 MBps and writes up to 410 MBps keep file transfers responsive. Random performance reaches 94,000 read IOPS and 35,000 write IOPS. Heavy media libraries or large game collections will exceed the available space and require secondary storage.

Perguntas sobre este artigo

How much sequential write speed drops when the 120GB TLC drive fills up?

The 120GB TLC NAND and Samsung MEX controller deliver up to 410 MBps sequential write when free space is available; sustained writes slow once the SLC cache is exhausted.

What heat or noise should I expect from the 2.5 inch SATA SSD running all day?

Idle power is 0.045W and the drive has no moving parts, so it produces no audible noise and negligible heat within the 0°C to 60°C operating range.

Which SATA cable and power connector must my motherboard or laptop already have for this 2.5 inch drive?

A standard SATA III data cable and a 15-pin SATA power connector are required; the 7.11mm height fits most 2.5 inch bays.
