You'll see both ordinary hard drives and swifter (but lesser-capacity) solid-state drives (SSDs) in under-$1,000 laptops. The occasional 15.6-inch-screen model might offer a small-capacity SSD boot drive alongside a secondary-storage platter hard drive, though this is more common with 17-inch laptops. Opt for this dual-drive approach if you can find it and afford it. The smaller SSD would be home to the operating system and a few favorite games, and the larger, more economical hard drive would host the rest of your games and other programs that don't need quick loading times. (It's indeed possible to split your Steam game library across drives.)
Dell Home, via its Member Purchase Program, offers its Dell 15.6" Laptop Gaming Backpack in Black/Red for $28.49 with free shipping. That's tied with our expired mention from four days ago as the lowest price we've seen for this bag. (It's the best deal we could find now by $20.) It accommodates laptops with up to 15.6" screens and features a shock-absorbent EVA molded front shield, adjustable shoulder straps, and a deployable rain cover.
