Samsung 840 EVO 1TB SATA SSD

The Samsung 840 EVO MZ-7TE1T0BW is a 2.5 inch internal solid state drive with a 1TB capacity and a SATA interface. It uses MLC memory and a Samsung 3-core MEX controller to deliver 540 MB/s sequential read and 520 MB/s sequential write speeds. The drive is designed for consumer desktops and notebooks.

Suits SATA upgrades and secondary storage.

This SSD fits any system with a 2.5 inch SATA bay, making it a direct upgrade for older laptops and desktops that still use the SATA interface. Users needing higher random IOPS, lower latency or enterprise-grade endurance should consider drives built for those workloads.

1TB capacity handles OS, apps and media libraries

The 1TB volume comfortably holds an operating system, a full application suite and large photo or video collections while leaving headroom for temporary files. Sequential workloads run at the rated 540 MB/s read and 520 MB/s write limits; sustained heavy write cycles will eventually reach the MLC endurance ceiling.

  • 98,000 IOPS random read for responsive apps

Questions about this item

Does this 2.5 inch SATA III SSD need a separate power cable or adapter to work in a desktop?

The drive uses the standard SATA data and power connectors, so a desktop only needs a free SATA port on the motherboard and a SATA power lead from the power supply. No extra adapter is required for the 2.5 inch form factor.

Will this SATA III drive run at full 540 MB/s read speed on a motherboard limited to SATA 3 Gb/s?

The drive is backward compatible with SATA 3 Gb/s ports, but the 540 MB/s sequential read and 520 MB/s write speeds require a SATA 6 Gb/s connection. On the older port, throughput will be capped at the lower bus limit.

How can I confirm the 1 TB Samsung 840 EVO is delivering its rated 98,000 IOPS random read performance after installation?

Run a benchmark tool such as CrystalDiskMark or AS SSD using the 4 KB random read test. Results approaching 98,000 IOPS indicate the drive and SATA III link are operating as specified.
