Why are PCIe Gen 4 SSDs a good deal on Prime Day 2025?
With the release of newer PCIe Gen 5 drives, older but still very fast PCIe Gen 4 SSDs are seeing significant price cuts. This makes them a great value for upgrading PCs, laptops, and the PS5 during the Prime Day event.
What is the main difference between 4TB and 8TB SSD deals?
4TB SSDs are highlighted as offering a lot of space for less money per gigabyte, making them a great value. 8TB SSDs are for users who need the most storage capacity possible for large game libraries and extensive work files.
What is CMR tech in hard drives and why is it better?
CMR (Conventional Magnetic Recording) is a recording technology that is better for most uses, like in PCs and NAS setups, because it handles different tasks and workloads with consistent speed. It is generally preferred over SMR (Shingled Magnetic Recording), which is slower for rewriting data.
What are the key things to check when buying an HDD?
When buying an HDD, you should look at four main things: the recording technology (CMR is best for most uses), the spin speed (RPM) for performance, the cache size for faster access to frequently used data, and the length of the warranty, which indicates reliability.
