Samsung 870 Evo SATA SSD Review: Give Your Old PC A Boost


Design And Form Factor

As the name suggests, this is a SATA SSD, which means it uses a SATA interface to connect with a laptop or a computer. If you are planning to use the Samsung 870 Evo SATA SSD with a desktop, it requires a SATA cable and a power cable from the power source unit.

On most laptops, one probably just needs to disconnect the already existing hard-disk and replace it with the 870 Evo SATA SSD. Also make sure that your laptop has a SATA style storage module before buying this, as most of the modern laptops only offer an NVMe SSD slot.

Considering the Evo 870 is a SATA SSD, it will definitely be slower than something like the NVMe Gen3 or the NVMe Gen4 SSD. Do note that, a SATA SSD will be way more affordable when compared to an NVMe SSD, which makes it a good storage option for users, who are on a budget but still want to experience faster read or write speeds.

A typical internal HDD with 5200 RPM can offer a peak write speed of 170MB/s, and if we achieve anything more than this on the Samsung Evo 870 SATA SSD should make it an interesting option. Having a faster storage drive will help your computer with the boot speed, and it can also improve the software or game-loading speed.



We ran CrystalDiskMark 7.0 and noted that the Samsung Evo 870 SATA SSD offered a peak read speed of 550MB/s, and a peak write speed of 485MB/s. These numbers indicate that the Evo 870 SATA SSD is at least thrice as fast as a typical HDD and doesn’t cost much.

We tried copying a big file from the computer to the Evo 870 SATA SSD, and we noticed a real-world write speed of around 400MB/s, which is almost in-line with the benchmark results. These numbers indicate that the Samsung Evo 870 is one of the fastest SATA SSDs in the market, which can resurrect an old PC or a laptop.
