500GB SATA III consumer SSD

The Samsung 840 EVO MZ-7TE500BW is a 2.5 inch internal solid state drive built for everyday consumer workloads. It offers 500GB of TLC flash memory managed by a Samsung 3-core MEX controller. The drive connects through a standard SATA III interface for broad system compatibility.

Low power draw and wide temperature range

Idle power consumption is rated at 0.14W and active use at 0.24W, keeping heat output minimal in normal operation. The drive is specified to operate from 0°C to 70°C with humidity tolerance from 5% to 95% RH. No moving parts mean silent running under any load.

6.8mm z-height fits standard 2.5 inch bays

The drive measures 6.8mm high, 69.85mm wide and 100.08mm deep, weighing 0.12 lbs, matching the typical 2.5 inch form factor for laptop or desktop installation. Standard SATA data and power connectors allow direct connection to existing cables. MTBF is rated at 1,500,000 hours for long-term reliability.

Questions about this item

How is the 2.5" SATA III drive installed, and what step is often missed?

Connect the SATA data cable to the motherboard and the SATA power connector from the PSU, then secure the drive in a 2.5" bay or bracket. The step often missed is enabling AHCI mode in the BIOS before installing the operating system.

What maintenance or replacement will the TLC NAND flash need later?

The TLC memory has a finite write endurance. Under heavy workloads the drive will eventually reach its program/erase cycle limit and require replacement. Samsung Magician software can monitor remaining life and trigger a secure erase if performance degrades.

What limit appears first during sustained writes on the 500GB model?

The TurboWrite SLC buffer fills after a few dozen gigabytes of continuous writes, after which sequential write speed drops from the peak 520 MBps toward the native TLC rate. Thermal throttling may also engage if the drive exceeds 70°C.
