From the above table, it is clear to see that an SSD out-performs an HDD in every attribute and so is the technology of choice for gaming PCs. However, there is a considerable cost difference between SSDs and HDDs. For this reason we recommend
installing your most performance sensitive data, such as Windows and games on an SSD, and bulky data such as music and videos on an HDD as these won’t benefit from the faster performance of the SSD.
There are a number of SSD size options to choose from the large 2.5in and 3.5in formats to tiny M.2 drives that connect directly to the motherboard.
Alongside the size options there are also a number of SSD interface choices too - SATA, U.2 NVMe and M.2 NVMe. SATA is the traditional PC drive interface and offers the slowest throughput, whereas the two NVMe types allow
much faster transfer speeds, especially if using PCIe 4.0.
