The most affordable way to make an older machine feel faster is by replacing the spinning hard disk drive with the Samsung SSD 870 EVO 2TB 2.5-inch SSD. The 2TB will hold your Windows install, a complete library of games, and years’ worth of photos on one drive, so you won’t have to worry about running out of space or moving anything to an external drive. Your PC can read data from it at speeds of up to 560 MB/s and write data to it at up to 530 MB/s, which is as fast as the SATA interface will allow. Samsung also provides free migration software that will help you transfer your current setup to this new SSD, and it has a five-year limited warranty.

A sizable SSD to help expand your computer’s storage capacity

The 2.5-inch size is the standard drive bay measurement for laptops and for desktop mounting brackets, so the 870 EVO drops into most machines without an adapter of any kind. It connects over SATA III at 6Gb/s, but it will also work on the older 3Gb/s and 1.5Gb/s ports, which means a desktop built ten years ago can take this drive without you adding a controller card first.

Intelligent TurboWrite reserves a section of the drive as a fast write buffer, and the buffer on the 2TB version is larger than the ones on the smaller capacities. What you notice is that a big file copy holds its speed further into the transfer instead of slowing down halfway through.
