500GB SATA III Consumer SSD

The Samsung 840 EVO MZ-7TE500BW is a 2.5-inch internal solid state drive built for consumer workloads. It connects through a SATA III interface and uses TLC memory components. The drive is rated for sustained sequential read speeds of 540MB/s and write speeds of 520MB/s.

TurboWrite Acceleration Feature

The controller employs TurboWrite technology to maintain high acceleration during everyday tasks. This approach uses a portion of the TLC array as a high-speed buffer to absorb burst writes. The Samsung 3-core MEX controller manages the process to deliver up to 98,000 random read IOPS and 90,000 random write IOPS.

Standard 2.5-Inch Installation

The drive fits any standard 2.5-inch bay with a 6.8mm height profile and draws 0.14W idle or 0.24W active. Alignment of the SATA data and power connectors is the only mechanical step required. Operating limits are 0°C to 70°C with humidity up to 95% RH.

Questions about this item

How long is the TLC memory in the 840 EVO rated to last before it needs replacing?

The drive carries an MTBF of 1,500,000 hours, which represents the manufacturer's reliability estimate for the TLC NAND and controller combined.

What speed ceiling will I hit first when writing large files continuously?

Sustained sequential write tops out at 520MBps, so that is the limit you will reach during long, large-file transfers.

How much heat and power should I expect when the SSD runs all day in a laptop?

Active power draw is 0.24W and the operating range is 0°C to 70°C, so heat output stays low even under continuous load.
