Amazon's Prime Day has produced a standout storage deal: the TeamGroup G50 EVO 4TB NVMe SSD is now $399.99, which works out to exactly 10 cents per gigabyte. That makes it the cheapest 4TB drive we've seen, undercutting most competitors by a wide margin. The drive uses a PCIe 4.0 interface, so it should deliver solid performance for everyday use, though the source doesn't specify exact read/write speeds.

The significance here isn't just the price per gigabyte—it's what that price signals for the storage market. A 4TB drive at this cost was unthinkable a year ago, and it suggests that high-capacity SSDs are finally becoming accessible to mainstream buyers. For gamers with large libraries or creators working with big video files, this deal offers a practical way to expand storage without breaking the bank.

Keep in mind that this is a Prime Day promotion, so the discount is likely temporary and stock may run out quickly. If you're in the market for a large, fast SSD, this is a compelling option—but act fast if you want it at this price.
