Firecuda 520 1Tb (Storage)

Firecuda 520 1Tb

All those high-end games obviously take a lot of space, and this M.2 drive is the best recommendation so far for gamers. This M.2 is specifically designed for gamers, and you can keep all your software and the most played games in this drive and get the most performance from it. This M.2 drive provides up to 5 GBs of speed. Transfer speed also matters in games, and it can change the performance of the games a little due to its high-speed delivery. This might not be a huge change, but it still matters. This drive comes with a 5 years warranty, which might be the most in its category.

High-end games need a good delivery speed to run smoothly, and we clearly don’t want our games to stutter while running on an RTX 3090. With this drive equipped with your pc, you will not be compromising performance at all. If 1 Tb is not much space for you, this drive also comes with a 2Tb version to keep all your games in one drive. We still recommend getting a 2TB SSD to keep all your games safe and so you do not delete or compromise on a game for another.

We recommend the best-looking case with the best ventilation system and even a proper cable management system. The tempered glass side panel on this case will show off all your high-end components in your rig, and the RGB will keep your aesthetic craving satisfied. NZXT cases are known for their sleek designs and their cable management system. Cable management actually makes a lot of clearance in your build, so you can easily show off your components while keeping them cool. Managing cables can affect the ventilation of your computer. Good ventilation means under control temperatures, which is our goal with this case.

The aforementioned CPU cooler fits perfectly on the top of this case while showing the CPU meter on the CPU clearly, and the RGB glow is also very prominent. Our RTX 3090 also has a lot of clearance space in this case, so the temperature on our GPU will also remain normal.
