Quick Answer
A 4TB NVMe SSD is the buy for SA gamers with large libraries who are tired of uninstalling games; expect a 2TB-to-4TB jump to comfortably hold 30-40 modern AAA titles. Target a Gen 4 4TB drive around 7,000 MB/s, since Gen 5 adds cost and heat without faster game loads.
Why 4TB Makes Sense Now
Modern AAA installs routinely run 80-150GB each, so a 1TB drive holds only a handful and a 2TB drive fills faster than expected. A 4TB drive lets you keep a large rotation installed plus media and project files without constant juggling. For anyone with a big library or who records gameplay, the capacity removes a recurring annoyance.
A single large drive also keeps everything on the fastest storage, avoiding the slow secondary SATA disk that bottlenecks load times for overflow games.
Picking The Right 4TB Drive
Gen 4 is the value choice at 4TB: around 7,000 MB/s reads is more than enough for gaming, and it runs cooler and cheaper than Gen 5. A DRAM-equipped drive holds performance better under sustained writes, which matters when you install many games at once. Confirm your board has a free M.2 slot, since 4TB drives are single-sided or double-sided and most slots accept either.
FAQ
How many games fit on a 4TB SSD?
Roughly 30-40 modern AAA titles at 80-150GB each, plus media and project files. It is enough to keep a large rotation installed without uninstalling to make room.
Should a 4TB drive be Gen 4 or Gen 5?
Gen 4 for gaming. It delivers about 7,000 MB/s, which is plenty for game loads, and runs cooler and cheaper than Gen 5. Save Gen 5 for heavy file work.
Does a DRAM cache matter on a 4TB drive?
Yes for sustained writes. A DRAM-equipped drive keeps speeds consistent when you install or copy many large files at once, where DRAM-less drives slow down.
4TB drive as your default install location in Steam and the Xbox app so new games land on the fast NVMe instead of a slower secondary disk.
