250GB SATA III TLC drive
The Samsung 840 EVO MZ-7TE250KW is a 2.5-inch internal solid-state drive with a 250GB capacity. It uses TLC memory components and a Samsung MEX controller over a SATA III interface. This drive suits users upgrading a laptop or desktop that accepts a standard 2.5-inch SATA device.
Build integration and system impact
The 7.11mm height fits most 2.5-inch drive bays and the package includes a bracket, screws, cables and a spacer for flexible mounting. A SATA data connection and a SATA power connection are required from the host system. Low idle power draw of 0.045W leaves more of the system power budget for other components.
Capacity headroom and limits
250GB provides space for an operating system, core applications and a working set of files. Sustained sequential reads of 540MB/s and writes of 520MBps, with 4KB random reads up to 97,000 IOPS and writes up to 66,000 IOPS, keep everyday workloads responsive. Heavy media libraries or large game collections will exceed the available space.

Domande su questo articolo
Will the 520MBps sequential write speed drop when the 250GB TLC drive fills up?
Sustained sequential write is rated at 520MBps; TLC NAND can slow once the SLC cache is exhausted, so performance may decrease as capacity is used
How much heat and power does the 840 EVO produce during all-day operation?
Idle power is 0.045W and the drive operates from 0°C to 60°C, so heat output is minimal and cooling requirements are low
Does the MZ-7TE250KW come with a SATA cable and bracket for a desktop install?
The package includes a bracket, screws, SATA cable, power cable, USB-to-SATA cable and drive spacer for direct desktop installation
